DHEA: A Smart Modulator for Immune Overreaction and Hormonal Balance

Introduction

You may know DHEA (dehydroepiandrosterone) as an adrenal hormone that declines with age, but it’s more than a precursor to sex hormones – it plays a key role in how your immune system balances itself. In conditions where immune cells overreact – such as Mast Cell Activation Syndrome (MCAS) or other TLR4-driven inflammatory states – DHEA may serve as a modulatory brake, helping calm the storm. But DHEA also has complex metabolic pathways, and under certain circumstances, it may convert into estrogen at a higher rate, particularly in the setting of inflammation and metabolic dysfunction.

Modulating Immune Receptors: TLR4 and the Inflammatory Alarm

The immune system senses danger using “radar” receptors called toll-like receptors (TLRs). TLR4 specifically reacts to lipopolysaccharide (LPS) from bacteria and can trigger powerful inflammation.

Research indicates that:

  • DHEA helps reduce TLR4-driven inflammation, limiting release of pro-inflammatory signals.
  • By toning down this TLR4 response, DHEA can be a protective factor when immune overreaction is a significant problem.

Calming Mast Cells in MCAS and Allergic Inflammation

Mast cells – key players in allergies and MCAS – release chemicals like histamine in response to triggers. In studies, DHEA has been shown to reduce mast cell degranulation, which helps dampen allergic and inflammatory symptoms such as gut irritation, flushing, or hives.

Balancing Cortisol with 11β-HSD Pathways

Cortisol, the stress hormone, and DHEA share the same adrenal origins. The enzyme 11β-hydroxysteroid dehydrogenase (11β-HSD) helps regulate cortisol activity inside cells.

  • DHEA supports a balanced cortisol-to-DHEA ratio, which is important for avoiding immune overactivation.
  • This balance allows the immune system to stay adaptable without collapsing into exhaustion or flaring into overdrive.

The Role of Mitochondria in Cortisol and Immune Balance

Mitochondria, the energy powerhouses, are also central to cortisol production. Cholesterol conversion into pregnenolone, the first step in cortisol synthesis, takes place in adrenal mitochondria. When mitochondria falter, cortisol production falls, and the balance with DHEA is disrupted.

Thus, mitochondrial health doesn’t just impact energy levels – it shapes how DHEA and cortisol interact to regulate inflammation.

DHEA, Estrogen Conversion, and Cytokine Storms

An important consideration is that DHEA can convert into estrogen through enzymatic pathways, especially when the enzyme aromatase is upregulated. This probability increases in states of:

  • Cytokine storms and inflammation: Pro-inflammatory cytokines (IL-6, TNF-α, prostaglandins) boost aromatase activity, increasing the likelihood that DHEA is diverted toward estrogen production.
  • Adiposity and visceral fat accumulation: Fat tissue is rich in aromatase, meaning obesity and insulin resistance can drive more estrogen from DHEA.
  • Hepatic dysfunction: Conditions such as fatty liver or fibrosis impair estrogen clearance, causing build-up.

This means that in autoimmune-like states with inflammatory surges, supplementing DHEA without addressing these underlying drivers could unintentionally lead to excess estrogen, which may complicate hormone balance further.

Practical Tools to Address Conversion Risk

  • Semaglutide and visceral fat: By reducing visceral adiposity, semaglutide (a GLP-1 agonist) indirectly reduces aromatase expression in fat tissue, lowering estrogen conversion pressure.
  • Resmetirom and hepatic fibrosis: This novel thyroid hormone receptor-β agonist has shown promise in improving fatty liver disease and reducing fibrosis. By restoring healthier liver function, resmetirom may improve estrogen clearance and reduce the conditions that favour DHEA’s conversion to estrogen.
  • Proteolytic enzymes and hepatic support: Enzymes such as serrapeptase and nattokinase have been studied for their anti-fibrotic and anti-inflammatory potential. Supporting liver health helps maintain estrogen clearance.
  • Curcumin and cytokine moderation: Curcumin, from turmeric, is known to reduce NF-κB activity and inflammatory cytokine production. By blunting cytokine storms, it reduces aromatase upregulation and thus estrogen buildup.

⚠️ Important Note: Both semaglutide and resmetirom are powerful interventions with effects that extend across multiple physiological systems. They are not simple over-the-counter tools but prescription medications that must be guided by a clinician. Before considering them, it is essential to consult a qualified medical provider to evaluate risks, benefits, and whether they are appropriate for your health profile.

Special Consideration: Long-Haul COVID and Exercise Recovery

An additional area of interest is long-haul COVID, where patients often struggle with exercise intolerance and poor recovery. One factor may be an ongoing macrophage activation syndrome-like state, leading to persistent inflammation and fatigue.

Given its ability to dampen TLR4-driven cytokine surges, modulate mast cell activity, and support a balanced cortisol-DHEA ratio, DHEA could hold potential as part of a broader management strategy for this group. Yet here, too, the risk of DHEA converting into estrogen in an inflamed, adipose, or fibrotic environment underscores the importance of identifying and addressing the causative drivers of inflammation first.

Practical Points to Consider

  • Test first: Assess DHEA, cortisol, estrogen levels, and metabolic markers before supplementing.
  • Address inflammation: Reduce cytokine drivers (diet, curcumin, lifestyle).
  • Target adiposity and insulin resistance: Approaches like semaglutide or lifestyle-driven weight loss reduce aromatase burden.
  • Support the liver: Resmetirom in fibrosis, proteolytic enzymes, and nutrient-rich strategies can improve clearance of estrogens.
  • Use DHEA carefully: Too much may raise estrogen; too little may be ineffective. Age, sex, and context all matter.

Final Thoughts

DHEA is not a blunt tool – it is an immune and hormonal tuner. It calms overactive TLR4 pathways, steadies mast cells, and works in balance with cortisol. But in inflamed or metabolically stressed states, it can convert more readily into estrogen, especially when cytokine storms, visceral fat, or liver dysfunction are present.

That’s why effective use of DHEA requires a whole-system view: balance inflammation, reduce adiposity, support the liver, and profile cortisol before supplementation. With these safeguards in place and with careful consultation if medications like semaglutide or resmetirom are considered – DHEA can help restore harmony, quieting the storm without tipping the body into a new imbalance.

Copper, Fasting, and the Hidden Link Between Energy and Immunity

Copper, Fasting, and the Hidden Link Between Energy and Immunity

When people think of fasting, they often imagine it as a universal path to better health: weight loss, cellular repair, and sharper thinking. Indeed, fasting has many well-documented benefits, from stimulating cellular clean-up processes (autophagy) to enhancing the activity of longevity-linked proteins called sirtuins. But like any biological process, fasting is not one-size-fits-all. The state of the body’s nutrient stores – especially copper – can radically change whether fasting helps or harms.

Copper may not be as well-known as iron or zinc, but it is just as essential. It plays a central role in how our cells make energy and how our immune system recognises threats. In situations of poor copper availability, fasting can sometimes backfire, putting extra stress on the brain and immune system. To understand why, let’s take a closer look at the science in a way that connects energy metabolism, red blood cells, immune balance, and the different forms in which copper exists in the body.

Copper’s Two Faces: Cu¹⁺ and Cu²⁺

Copper exists in two main biological forms:

  • Cu¹⁺ (cuprous copper, 28 electrons)
  • Cu²⁺ (cupric copper, 27 electrons)

This small difference in electron count has major biological consequences. Cu¹⁺ is the reduced form, most effective for driving the proton pump of cytochrome c oxidase (Complex IV) in mitochondria – the final enzyme of the energy chain. By enabling protons to be pushed across the mitochondrial membrane, Cu¹⁺ powers ATP synthase, the turbine that generates cellular energy.

Cu²⁺, in contrast, is more oxidising. It circulates mostly extracellularly, often bound to proteins like ceruloplasmin. When unbuffered, excess Cu²⁺ can drive free radical chemistry, contributing to oxidative stress. The balance between these two states – Cu¹⁺ inside cells and Cu²⁺ in circulation – is tightly controlled by the body.

When too little Cu¹⁺ is available for mitochondria, electrons back up in the energy chain, leak out, and form damaging superoxide radicals. Over time this leads to mitochondrial instability, cytochrome c loss, and accelerated cellular aging.

Fasting and Mitochondrial Stress

Fasting is often praised for boosting health. It encourages cells to burn fat, activate protective proteins (sirtuins), and clean out damaged components (autophagy). But fasting also increases the flow of electrons through the mitochondrial chain.

If Complex IV is well-supplied with Cu¹⁺, this added traffic is handled efficiently. If copper delivery is poor, however, the extra electron load produces more leaks and free radicals. In such cases, fasting could paradoxically worsen oxidative stress, especially in the brain. This is why fasting may be contraindicated in states of copper deficiency or poor intracellular copper delivery.

Copper in the Blood: Red Cells, Ratios, and Immune Clues

Copper balance isn’t just about “how much” is in the body – it’s about where it is, and in what form. Red blood cells (RBCs) carry significant amounts of copper to tissues, supporting oxygen use and mitochondrial function.

Researchers also look at mineral ratios and immune cell counts for clues:

  • Copper-to-zinc ratio: Too much zinc can suppress copper; balance between the two is often more important than the absolute value.
  • Neutrophil-to-lymphocyte ratio (NLR): Copper influences this in two very different ways:
  • Overall copper deficiency can impair neutrophil development, leading to neutropenia (low neutrophil count) and a weakened immune defence.
  • Excess extracellular Cu²⁺ with poor intracellular Cu¹⁺ availability can drive neutrophil over-activation, resulting in a heightened NLR. This can tip the body toward autoimmune-type inflammation, where neutrophils release sticky webs called neutrophil extracellular traps (NETs). While NETs help fight infection, in excess they contribute to fibrotic tissue build-up and organ damage.

In summary: too little copper weakens defence, while the wrong distribution of copper can overstimulate immunity and drive tissue damage.

Different Copper Interventions

Copper can be replenished in different forms, and the form makes a difference:

  • Chelated or bisglycinate copper: Common supplement forms, supportive for general intake, but not always optimal for intracellular delivery.
  • Cuprous nicotinic acid (Cu¹⁺-NA): A form that delivers copper in the active 28-electron (Cu¹⁺) state that mitochondria prefer, potentially improving direct uptake into cells and Complex IV function.
  • GHK-Cu: A naturally occurring tripeptide (glycyl-L-histidyl-L-lysine bound to copper). Its key functions are:
  • Binding excess extracellular Cu²⁺ to reduce oxidative stress.
  • Transporting copper into cells where it can be converted to Cu¹⁺ and support mitochondrial energy production.
  • Supporting antioxidant systems, including glutathione recycling, to defend against oxidative damage.
  • Promoting tissue repair and reducing inflammation, which has been shown in wound-healing and anti-fibrotic research.

In the context of fasting and copper imbalance, GHK-Cu may help by both cleaning up harmful extracellular copper and enhancing intracellular copper availability, protecting energy metabolism and immune balance.

Immunity and Energy: Two Sides of Copper’s Role

Copper deficiency doesn’t just starve mitochondria of energy – it also blunts the immune system’s ability to recognise and respond to threats. Enzymes that help immune cells “present” antigens (the molecular ID tags of invaders) are copper-dependent. Without copper, immune precision falters: the body may underreact with weak infection control or overreact with inappropriate inflammation.

When extracellular Cu²⁺ dominates but intracellular Cu¹⁺ is lacking, the risk shifts: neutrophils become hyperactive, NLR rises, and excessive NET formation can trigger autoimmune inflammatory responses and fibrosis.

Thus, copper sits at a crossroads: it powers the energy factories of our neurons and immune cells, and it fine-tunes the recognition systems that govern immunity.

Benefits of Fasting – When Copper Is in Balance

With balanced copper, fasting can:

  • Enhance autophagy: Clearing damaged parts of cells.
  • Activate sirtuins: Proteins linked to DNA repair, mitochondrial efficiency, and stress resilience.
  • Reset metabolism: Improve insulin sensitivity and hormone balance.

But without copper – especially Cu¹⁺ – these benefits may not appear, and fasting could add to stress.

The Flaws and Considerations

  1. Not universal: Fasting can worsen stress in copper-deficient states.
  2. Form matters: Cu¹⁺ forms (like cuprous nicotinic acid) may be more directly beneficial for mitochondria than generic salts.
  3. Immune risk: Too little copper weakens immunity, while poor copper distribution can overstimulate neutrophils and promote autoimmune-like inflammation.

Moving Toward Balance

The lesson is not to abandon fasting altogether, but to approach it wisely. Before engaging in prolonged fasting:

Assess mineral status, especially copper and zinc.

  • Ensure copper is available in the right form for mitochondria.
  • Consider support from GHK-Cu if extracellular copper overload is suspected.
  • Maintain glutathione and antioxidant systems to buffer stress.

Final Thought

Fasting is a powerful tool – but like all tools, its effects depend on the foundation beneath it. Copper, in both its forms, is central to that foundation. With balanced Cu¹⁺ and Cu²⁺, fasting enhances energy, brain health, and immunity. Without that balance, fasting risks accelerating decline through oxidative stress, immune imbalance, and fibrosis.

Is Your Jaw Pain More Than Just Stress? Exploring the Hidden Link Between Viral Reactivation and TMJ Dysfunction

Temporomandibular Joint Dysfunction – or TMJ, is a common yet often misunderstood condition. It typically shows up as jaw pain, popping sounds, facial tension, or difficulty chewing. Many people assume it’s caused purely by stress, teeth grinding, or poor posture. While these factors certainly play a role, emerging science points to a deeper, lesser-known culprit hiding in plain sight: stealth viral infections – particularly the Epstein-Barr Virus (EBV).

You may have heard of EBV as the virus behind mononucleosis, often called “the kissing disease.” What’s not as widely known is that EBV, once inside your body, never truly goes away. It hides silently in your cells, especially immune cells, waiting for an opportunity to reactivate. This reactivation doesn’t always bring on full-blown illness. Instead, it can cause vague, persistent symptoms – fatigue, brain fog, muscle aches, and, surprisingly, jaw and facial pain.

So how does a virus like EBV connect to jaw tension?

Let’s start with the immune system. When stealth viruses reactivate (often due to chronic stress, poor sleep, or a weakened immune system), they can cause low-grade inflammation throughout the body. Inflammation is your body’s natural defense mechanism, but when it becomes chronic, it starts to attack healthy tissues – including joints.

The temporomandibular joint is a small but complex hinge that connects your jawbone to your skull. Like any joint, it can become inflamed. If your body is already dealing with systemic inflammation due to a reactivated virus, the TMJ can become one of the unintended targets. That inflammation may not only cause pain but also increase nerve sensitivity, leading to jaw tightness, facial aches, and even referred pain to the ears or temples.

But there’s more. EBV can also affect the nervous system. One of the main nerves involved in jaw movement and facial sensation is the trigeminal nerve. When stealth viruses disturb this nerve – either through inflammation or direct irritation – it can mimic or worsen TMJ symptoms, sometimes leading doctors and patients down a path of dental treatments that miss the root cause.

Furthermore, the stress of chronic viral activation can create a vicious cycle. When you’re not feeling well, you’re more likely to clench your jaw, grind your teeth at night, or develop poor posture – all of which strain the TMJ further.

So, what can you do?

First, don’t panic – this doesn’t mean every case of TMJ is viral. But if you’ve struggled with chronic TMJ symptoms, fatigue, or brain fog, and traditional treatments haven’t helped, it might be worth considering an underlying immune or viral issue. Supportive therapies that reduce inflammation, strengthen the immune system, and regulate stress can sometimes provide unexpected relief—not just for your energy levels, but for your jaw too.

In short, your body speaks in whispers before it screams. That nagging jaw pain could be more than muscular tension – it might be your immune system asking for help.

Nature, NK Cells, and Stealth Viral Protection: Restoring Adrenal Health

Nature, NK Cells, and Stealth Viral Protection: Restoring Adrenal Health

Building on our previous discussion about stealth viral infections and their subtle yet profound impacts on adrenal function, this week’s edition draws inspiration from a recent TIME feature titled “The Healing Power of Nature”. This insightful article highlights how nature exposure significantly enhances natural killer (NK) cell activity, crucial for managing stealth viruses such as Epstein-Barr virus (EBV), Cytomegalovirus (CMV), and HHV-6.

Stealth viruses quietly disrupt adrenal health through chronic, low-grade inflammation. NK cells represent a frontline defence, rapidly identifying and eliminating virally-infected cells before these pathogens can embed deeply within tissues, including the adrenal cortex. Notably, research has demonstrated that even short-term exposure to natural environments, such as forests, boosts NK cell numbers and their cytotoxic capacity for extended periods, offering sustained protection against viral infiltration (1).

The enhancement of NK cells by nature exposure helps counteract the persistent immune evasion strategies employed by stealth viruses. By elevating NK cell activity while simultaneously reducing cortisol production – a hallmark of stress and inflammation – nature exposure disrupts the harmful cycle linking viral infections to adrenal fatigue and mitochondrial dysfunction. This dual action creates a beneficial hormonal and immunological environment, significantly mitigating the chronic stress exploited by these viruses (2).

Complementing nature exposure with specific nutraceutical strategies can further bolster NK cell function and provide crucial adrenal support. Active Hexose Correlated Compound (AHCC) has been clinically shown to significantly increase NK cell activity. Astragalus root enhances both NK cell function and adrenal resilience. Essential nutrients like Vitamin D3 and Zinc are foundational for optimal immune responses and NK cell efficiency. Additionally, adaptogenic herbs such as Ashwagandha and Rhodiola effectively normalize cortisol levels, thus reducing adrenal stress and supporting mitochondrial health. Furthermore, nutraceuticals like IP6 (inositol hexaphosphate) and transfer factors have demonstrated notable improvements in NK cell activity, providing additional immune-enhancing support.

In cases where stealth viral infections inhibit vitamin D receptor (VDR) function, the use of certain antihypertensive medications such as angiotensin receptor blockers (ARBs) might be beneficial. These medications have been shown to modulate immune responses by acting on VDR pathways, thereby potentially restoring vitamin D signalling impaired by viral infections (3).

Alongside nutraceutical interventions, lifestyle practices are fundamental in reinforcing immune and adrenal resilience. Regular visits to natural settings like forests or parks amplify NK cell activity and reduce adrenal stress. Mindfulness practices effectively lower cortisol-driven inflammation, limiting opportunities for viral reactivation. Moderate exercise consistently boosts NK cells and enhances mitochondrial and adrenal health. Furthermore, optimizing sleep quality supports adrenal recovery, boosts NK cell production, and facilitates mitochondrial repair.

At a cellular level, chronic stealth viral infections trigger sustained inflammation, perpetuating what has been termed the cellular “danger response.” This pathological metabolic state severely impairs mitochondrial efficiency and adrenal function. However, regular nature exposure therapeutically interrupts this process by simultaneously reducing cortisol, enhancing NK cell surveillance, and improving mitochondrial energy production, effectively addressing the underlying pathophysiological mechanisms (2).

To practically integrate these insights, a comprehensive protocol addressing stealth viral impacts should include routine nature exposure – such as weekly forest bathing or visits to parks – to boost NK cells and adrenal health. Nutraceuticals like AHCC, Astragalus, Vitamin D3, Zinc, adaptogenic herbs, IP6, and transfer factors are vital supplements. Lifestyle practices including mindfulness meditation, regular moderate exercise, optimized sleep patterns, and controlled cold exposure further support resilience. Lastly, nutritional support with B vitamins and magnesium is recommended to strengthen mitochondrial and adrenal vitality.

In conclusion, integrating nature exposure, targeted nutraceuticals, supportive lifestyle interventions, and potentially antihypertensive medications offers a robust and unified approach to managing stealth viral infections and restoring adrenal health. By enhancing NK cell activity, reducing cortisol-driven inflammation, and supporting mitochondrial function, we effectively protect adrenal integrity and transform chronic stress into sustained health and vitality.

Until our next edition,

Justin.

Stealth Viral Infections, Autoimmunity, and the Hidden Impact on Adrenal Health

Stealth Viral Infections, Autoimmunity, and the Hidden Impact on Adrenal Health

In the world of modern medicine, symptoms like chronic fatigue, low blood pressure, brain fog, and digestive issues are often approached in isolation. However, a growing body of research – and a deeper understanding promoted by leaders like Professor Robert Naviaux, Dr. Dietrich Klinghardt, and Dr. Paul Cheney – suggests that underlying stealth viral infections may be quietly driving these diverse expressions of disease. Among the most affected systems? The adrenal glands, immune signalling, and gut integrity.

The Role of Stealth Viruses in Autoimmune-Like Presentations

Stealth viruses are not your typical infections. These include chronic, low-grade or latent viruses such as cytomegalovirus (CMV), Epstein-Barr virus (EBV), and human herpesvirus-6 (HHV-6). They often escape routine detection and don’t always cause acute symptoms. Instead, they subtly disrupt cellular function and trigger abnormal immune responses that resemble autoimmune conditions.

One of the most significant connections being explored is between CMV and the adrenal glands. In healthy individuals, the adrenal glands produce critical hormones like cortisol and aldosterone, which regulate everything from blood pressure to inflammation. But CMV has been shown to infect adrenal tissue directly in some individuals, especially those who are immunocompromised.

CMV and 21-Hydroxylase Antibody Mimicry (Theoretical Risk)

What makes CMV particularly insidious is its potential to theoretically mimic adrenal autoimmunity. Some researchers propose that CMV antibodies may cross-react with 21-hydroxylase – a key enzyme used by the adrenal glands to produce cortisol and aldosterone. This molecular mimicry could, in theory, lead to immune confusion, where the body starts attacking adrenal tissue as if it were viral in nature. While this mechanism is not yet confirmed by direct human studies, it offers a compelling explanation for why some individuals present with adrenal symptoms without classic autoimmune markers. This process may resemble the autoimmune pathway of Addison’s disease, even if classical tests do not reflect full adrenal failure.

When Tests Are Misleading: The ACTH-Cortisol Paradox

Most clinicians screen for adrenal insufficiency using blood levels of cortisol and ACTH (adrenocorticotropic hormone). However, in the presence of viral-induced immune activation, these markers can be misleading. Cytokines – chemical messengers released during chronic inflammation – can artificially elevate or suppress cortisol and ACTH without reflecting true adrenal gland function.

This means that someone may appear “normal” on a standard cortisol test, yet still suffer from classic symptoms of adrenal insufficiency due to viral interference or immune mimicry. This false-negative scenario is more common than many realize, especially in chronic fatigue states, fibromyalgia, and autoimmune overlap syndromes.

Symptoms That Often Go Unrecognized

Many of the symptoms associated with Addison’s disease or adrenal suppression are subtle but pervasive. These include:

Physiological Symptoms:

            •           Low blood pressure or dizziness when standing up

            •           Salt cravings

            •           Chronic fatigue unrelieved by rest

            •           Nausea or poor appetite

            •           Muscle weakness

            •           Darkening of the skin (hyperpigmentation)

Emotional & Cognitive Symptoms:

            •           Brain fog

            •           Low stress tolerance

            •           Anxiety or inner restlessness

            •           Depressive episodes

            •           Emotional detachment or apathy

These symptoms can easily be dismissed or attributed to “burnout” or stress, especially when lab markers are borderline or within so-called normal ranges.

The Gut-Adrenal-Immune Axis

Chronic viral infections don’t just impact the adrenal glands – they also affect gut health. Inflammatory cytokines produced during immune responses to stealth viruses can disrupt gut barrier integrity, leading to a leaky gut and increased susceptibility to gastrointestinal conditions.

This is why we often see overlapping diagnoses such as:

            •           IBD (Inflammatory Bowel Disease)

            •           Crohn’s Disease

            •           Ulcerative Colitis

            •           IBS (Irritable Bowel Syndrome)

Research has shown that stress hormones like cortisol normally play a protective role in gut barrier function. When cortisol is dysregulated due to immune mimicry or stealth viral interference, gut permeability increases. This sets up a vicious cycle where immune triggers in the gut further disrupt endocrine function – and vice versa.

A Precision Medicine Perspective

In conclusion, stealth viral infections such as CMV can have profound, far-reaching effects on the body – triggering autoimmune-like symptoms, confusing hormone signalling, and eroding gut health. Yet, because conventional testing often fails to detect these dynamics early on, many people are left misdiagnosed or untreated.

Precision medicine asks us to step back and look at the entire terrain. It is not enough to chase a single pathogen or treat an isolated lab result. We must understand the interplay between immune activation, hormonal feedback, gut health, and environmental exposures.

As Professor Naviaux notes in his Cell Danger Response theory, healing cannot happen when the body is stuck in a threat-based metabolic state. Dr. Klinghardt emphasizes terrain over germ, and Dr. Cheney reminds us that biological complexity requires multidimensional solutions.

Through this lens, restoring adrenal vitality isn’t just about giving hydrocortisone or boosting cortisol. It’s about addressing underlying stealth infections, calming immune chaos, repairing the gut lining, and gently guiding the body out of a defensive posture.

True recovery lies not in reductionism, but in integration. And it begins by asking the right questions – not just “What’s the diagnosis?” but rather, “What story is the body trying to tell?”

Why We Crave Gluten: A Hidden Dialogue Between the Brain, Mitochondria, and the Immune System

Most people think of gluten cravings as simply a love for bread, pasta, or pastries. But behind this common desire may lie a far more complex conversation happening between the brain, the immune system, and our cells’ energy factories — the mitochondria. Emerging evidence suggests that gluten-rich foods might temporarily calm certain kinds of cellular “noise” in the nervous system, especially when energy metabolism or neurotransmitter balance is disrupted. This idea may also shed light on why gluten sensitivity, brain fog, and even aspects of neurodivergence — such as autism spectrum traits — often intersect in fascinating and sometimes confusing ways.

⸻

A Hypothesis: Gluten as a Short-Term Calming Signal

To understand the craving for gluten, it helps to first look at how the body regulates energy and stress at the cellular level. When cells are under pressure — from inflammation, oxidative stress, or poor mitochondrial efficiency — they tend to release a molecule called ATP into the space outside the cell. While ATP normally fuels the body from within, when released outside it acts as a danger signal, stimulating nearby immune and nerve cells and causing an inflammatory response. This phenomenon is known as purinergic signaling.

If the release of ATP becomes excessive, the system can enter a hyper-excitable state — nerves fire too readily, the immune system stays on alert, and sensations of anxiety, pain, or muscular tension may increase. The body naturally tries to balance this by converting ATP into adenosine, a calming molecule that suppresses inflammation and relaxes neural activity.

Here’s where gluten enters the picture. Gluten-derived peptides interact with an enzyme called DPP-4 (dipeptidyl-peptidase-4), which normally anchors another enzyme called adenosine deaminase (ADA). ADA’s job is to break down adenosine. When gluten interferes with DPP-4, ADA can’t do its job as efficiently — and adenosine levels rise.

That increase in adenosine may momentarily dampen the inflammatory and neural hyper-excitability caused by ATP release. In other words, gluten may provide a temporary biochemical “quieting” effect for some individuals whose nervous systems are overstimulated. The craving for gluten might therefore reflect not just habit, but a subconscious attempt to restore calm in an overactive cellular environment.

⸻

The Mitochondrial Connection: Dehydrogenase Activity and Energy Flow

But why would some people experience this hyper-excitability in the first place? One clue lies in the mitochondria — tiny power plants inside our cells that depend on a group of enzymes called dehydrogenases. These enzymes (such as PDH, α-ketoglutarate dehydrogenase, and succinate dehydrogenase) feed electrons into the electron transport chain (ETC) to make ATP.

When dehydrogenase function falters — whether due to nutrient deficiencies, oxidative stress, or inherited metabolic tendencies — the cell’s ability to produce clean energy drops. This leads to a buildup of partially oxidized metabolites like succinate, which can further drive inflammation through immune receptors such as SUCNR1. The body experiences this as a kind of internal “static”: energy demand increases while efficiency falls, triggering stress responses in both neurons and immune cells.

Under these conditions, the nervous system may release more ATP into the extracellular space, heightening purinergic signaling and inflammation. Gluten-induced adenosine accumulation might blunt this reaction — a biochemical coping mechanism for mitochondrial stress. This may help explain why gluten cravings can be especially strong in people who feel fatigued, anxious, or mentally overstimulated.

⸻

Serotonin, Dopamine, and Neurodivergence

Serotonin and dopamine — two key neurotransmitters — also play an intricate role in this balance. When mitochondrial efficiency declines, serotonin production in the gut and brain can drop, while dopamine pathways may become overactive.
• Serotonin generally acts as a paracrine calming molecule, modulating sensory and motor excitability and softening muscle tension through receptors found in peripheral tissues and sensory endings such as Pacinian and Ruffini corpuscles.
• Dopamine, on the other hand, amplifies neural firing and reward drive, enhancing sensitivity and sometimes increasing restlessness or impulsivity.

In neurodivergent states such as autism, this imbalance — reduced serotonin tone with heightened dopamine activity — is often documented. The body may seek ways to self-regulate, and consuming gluten could momentarily restore balance through its effects on adenosine signaling.

This doesn’t mean gluten is beneficial in the long term. Chronic activation of this pathway may calm inflammation but can also impair executive function, focus, and cognitive flexibility, all of which rely on finely tuned dopaminergic control. Thus, gluten cravings might represent a biochemical trade-off: relief from cellular overstimulation at the expense of mental clarity and long-term metabolic health.

⸻

Supporting the Transition Away from Gluten

For individuals who feel better reducing or eliminating gluten but struggle with cravings or withdrawal fatigue, addressing the underlying metabolic imbalance is essential. Supporting the dehydrogenase network helps restore efficient mitochondrial function, reducing the need for adenosine-based “chemical sedation.”

Key nutritional cofactors that aid this process include:
• Riboflavin (Vitamin B₂): Converts to FAD, a cofactor for succinate dehydrogenase and other flavoproteins in the ETC.
• Thiamine (Vitamin B₁): Crucial for pyruvate and α-ketoglutarate dehydrogenase activity.
• Niacin (Vitamin B₃): Replenishes NAD⁺, supporting redox balance and ATP synthesis.
• Lipoic acid: Recycles cofactors and reduces oxidative stress within dehydrogenase complexes.
• Magnesium and manganese: Support ATP stabilization and enzyme activity.
• Lithium (in trace nutritional form): Stabilizes mood and enhances mitochondrial resilience and neurogenesis.

Together, these nutrients can revitalize the cell’s energy network, reducing excess ATP release and calming purinergic overactivation naturally. When combined with adequate hydration, sunlight exposure, and gentle physical activity — which improve mitochondrial oxygen use — the body gradually regains balance without needing gluten’s biochemical “shortcut.”

⸻

In Summary

The craving for gluten may not just be psychological or cultural; it could represent the body’s instinctive attempt to modulate cellular stress. Gluten temporarily raises adenosine levels by interfering with enzymes that clear it, calming inflammation and neural excitability. Yet this soothing comes at the cost of executive function and long-term energy efficiency.

By improving mitochondrial dehydrogenase function and restoring serotonin–dopamine balance through proper nutrition, lifestyle support, and mindful dietary change, it becomes possible to quiet the body’s internal noise naturally — no gluten required. What begins as a craving can thus become a clue: a message from the mitochondria asking not for more wheat, but for more energy harmony.

Mitochondria, Purinergic Signalling, and the Modern Immune Storm: Understanding the Cell Danger Response

Most people think of the immune system as white blood cells fighting infections. But underneath this familiar picture is an even older guardian: the mitochondria. Known as the “powerhouses” of the cell, mitochondria are also decision-makers that help the body sense when something is safe and when it’s under threat. They do this not just by making energy but also by sending out stress signals that can either protect us – or, if stuck in overdrive, contribute to illness.

The Cell Danger Response

Dr. Robert K. Naviaux has described a universal stress program called the Cell Danger Response (CDR). When a cell senses injury, infection, or chemical exposure, it shifts from its usual “growth and repair” mode into “defence” mode. Instead of producing energy efficiently, mitochondria begin sending out danger signals to alert neighbouring cells and the immune system.

In the short term, this protective response helps the body focus on survival. But if the CDR stays switched on, cells remain trapped in defence mode. This stalled recovery can contribute to fatigue, chronic inflammation, and long-lasting illness.

Purinergic Signalling – The Cell’s Alarm System

One of the main ways stressed cells communicate is by releasing ATP, the same molecule usually used for energy inside cells. When ATP is released outside the cell, it acts like a red flare, telling the immune system that something is wrong.

ATP binds to specialized receptors on immune cells (called P2X and P2Y receptors) and sparks cascades that control inflammation, cell death, and tissue repair. For example:

  • Caspase-1 activation drives inflammatory proteins like IL-1β.
  • Caspase-3 and -9 help regulate programmed cell death.

When ATP release is balanced, these processes guide healthy immune surveillance. But if too much ATP is released – often through stress channels like pannexin-1 pores – the result can be an overamplified alarm, causing excessive or misdirected immune activity.

Environmental Pressures on Mitochondria

Modern exposures add fuel to this imbalance. Petrochemicals, pesticides, and industrial pollutants can act as electrophiles – molecules that interfere with the cell’s redox (electron-balancing) systems by binding to sensitive proteins. This disrupts how mitochondria regulate detoxification and defence.

Other environmental factors, like electromagnetic fields (EMF), are not electrophiles, but some experimental studies suggest they may contribute to oxidative stress. The science here is mixed and still under review, but it highlights how modern environments can tip the balance against cellular stability.

T-Helper Cells and Immune Balance

When mitochondria remain in defence mode, the effects ripple outward to higher layers of immunity. CD4⁺ T-helper cells – which coordinate the immune response – depend on mitochondrial signals to decide whether to activate Th1 (antiviral/antibacterial), Th2 (allergy/antibody), Th17 (tissue inflammation), or Treg (regulatory) programs.

Mitochondrial dysfunction doesn’t create one predictable outcome, but it can bias the balance. The result is a skewed immune tone: sometimes under-reacting to infections, other times over-reacting with inflammation.

Autoinflammatory vs. Autoimmune

It’s important to distinguish between two often-confused processes:

  • Autoimmune disease: when the adaptive immune system, especially antibodies, mistakenly targets the body’s own tissues.
  • Autoinflammatory disease: when the innate immune system overreacts to stress or danger signals, without antibodies being directly involved.

Persistent mitochondrial stress and distorted purinergic signalling more often fuel autoinflammatory cascades. These reactions can, in turn, confuse the adaptive immune system, leading to less precise antibody responses. This overlap is one reason why chronic inflammation is sometimes mistaken for autoimmunity.

Antigen Presentation and Pathogen Strategies

When purinergic signalling is disturbed, antigen-presenting cells (like dendritic cells) may struggle to accurately present microbial fragments to T-cells. This weakens immune “memory” and precision. Opportunistic pathogens exploit this weakness. Many microbes even release proteins that block complement activity, disabling one of the innate immune system’s key weapons.

The result is a vicious cycle: weakened recognition, chronic low-level infections, and ongoing inflammation.

Pulling It Together

Seen as a whole, mitochondria are not just energy factories – they are guardians of immune balance.

  • When healthy, they regulate ATP release, keep purinergic signalling in check, and support precise immune responses.
  • When stressed by environmental toxins, nutrient deficiencies, or infections, mitochondria may overshoot, sending distorted alarms that keep the immune system stuck in high-alert mode.
  • This “stuck” cell danger response explains why chronic inflammation, fatigue, or immune misfires often persist long after the original trigger is gone.


Why This Matters Today

For the everyday person, the key is not memorizing receptor names but grasping the bigger lesson:

  • Chronic inflammation is not always about an overactive immune system “attacking itself.”
  • Often, it reflects cells trapped in survival mode due to stress signals that never reset.
  • Modern pollutants, chemicals, and perhaps even electronic exposures add strain to this already sensitive balance.

Supporting mitochondrial health – through good nutrition, lowering environmental burdens, improving detoxification, and managing stress – can help restore the cell’s ability to switch back into growth and repair.

Conclusion

Mitochondria act as ancient guardians of our immune system. They help decide when to fight, when to rest, and when to repair. Understanding the cell danger response and purinergic signalling gives us new insight into many chronic illnesses. Rather than focusing only on the immune system as the problem, we can see how restoring mitochondrial balance may help the body move out of survival mode and back into harmony.

Melatonin: The Overlooked Molecule That Calms, Repairs & Rejuvenates Problematic Skin

If you’ve spent time and money on skincare and still feel frustrated with the results, it may be time to try a product that contains a molecule proven to repair and illuminate your skin.

Lumevie features what some call a miracle ingredient Melatonin.

Most know melatonin as a sleep hormone. But its role in skin health is deeper, especially for those with inflammation (e.g. eczema), sensitivity (e.g. rosacea), or early aging.

Your skin naturally produces melatonin as part of its repair system. But stressors like UV, pollution, poor sleep, and inflammation can overwhelm its defenses. That’s where topical melatonin helps.

At Lumevie, we use melatonin in its most bioavailable form, designed to work at night when skin repair peaks. Our formula also includes copper peptides, resveratrol, and methylene blue. Together, these support skin while melatonin leads the healing. Lumevie helps calm inflammation, protect cells, and boost regeneration at the cellular level.

Lumevie means “light” and “life” exactly what I needed in my own healing, and what I hope to offer you on your skin journey.

What Melatonin Does for Skin

1. Topical melatonin reduces inflammation safely without long-term steroid or immunosuppressant risks.
 Lumevie targets conditions like psoriasis, rosacea, and eczema by lowering inflammatory messengers (cytokines), helping to calm visible redness and irritation while supporting the skin’s natural immune response.

2. Melatonin boosts ceramide production and improves the function of the skin’s tight junctions.
 Lumevie restores a damaged skin barrier the root of dryness and reactivity. As skin begins to retain moisture more effectively, it becomes noticeably more stable, resilient, and radiant over time.

3. Melatonin works inside mitochondria, where oxidative damage hits hardest.
 It supports DNA repair, protects collagen, and maintains cellular energy reaching deeper than surface antioxidants like vitamin C. This is crucial for skin affected by accelerated aging, pigmentation, or chronic stress.

Lumevie uses melatonin to neutralize cellular stress where it starts deep inside skin cells resulting in healthier, more energized skin that glows from within.

4. Melatonin aligns with your circadian rhythm.
 At night, when skin heals, it boosts collagen, hydration, and recovery. Especially for those with poor sleep or high stress, it helps restore natural healing rhythms.

Lumevie is designed to work in harmony with your skin’s nighttime repair cycle, helping to restore balance and enhance overnight regeneration while you sleep. Lumevie doesn’t stop at melatonin. It also includes GHK-Cu peptides, resveratrol, and methylene blue each with powerful repair benefits. These ingredients were part of my healing and now they’re part of yours. In the upcoming articles, I’ll share how each one supports real transformation.

Poor Cortisol: Effect on Depression and Metabolic Resistance

What if the reason you’re feeling foggy, tired, puffy, or struggling with your weight isn’t about your motivation – but about how your body is trying to survive?

We’re often told that stress is bad for us, but rarely are we shown how our biology adapts to stress – and how that adaptation, if stuck, can quietly sabotage our energy, weight, and even thinking.

Let’s talk about something that’s affecting more people than we realize: hidden infections and toxins that interfere with how the body processes stress hormones. These infections don’t cause fevers or obvious illness. Instead, they linger silently and throw off important systems – especially the ones that control metabolism and energy.

One of the key systems involved is how your body manages a hormone called cortisol, often known as the “stress hormone.” In healthy doses, cortisol helps us wake up in the morning, keep blood sugar balanced, fuel our brain, and regulate hunger. But problems begin when the body starts converting too much of it into its inactive form, cortisone.

This shift happens through a mechanism driven by enzymes – particularly one called 11-beta hydroxysteroid dehydrogenase type 2, or 11β-HSD2 for short. When this enzyme becomes too active – often due to stealth infections, mold exposure, or heavy metal toxins – your body starts breaking down cortisol too quickly. That means you end up with too little of the active form (free cortisol), and too much cortisone, which your body can’t use to respond to stress or regulate metabolism.

Why does this matter?

When cortisol levels are low, your brain struggles to stay clear, focused, and emotionally balanced. You may feel foggy, unmotivated, or even emotionally numb – not because you’re lazy or weak, but because your brain isn’t getting enough of the fuel it needs.

This hormonal imbalance also impacts two key appetite-regulating hormones: ghrelin and leptin. Ghrelin tells your brain that you’re hungry. Leptin tells your brain that you’re full. In a well-balanced system, cortisol helps regulate ghrelin and keep hunger patterns in sync. But if cortisol is too low – or converted into cortisone too quickly – ghrelin signaling can get out of control, making you feel hungry even when you’ve eaten. At the same time, excess cortisol (especially when chronic) can reduce leptin levels or make your brain resistant to its signals, meaning you don’t feel full even after a meal.

This creates a powerful hormonal storm that leads to cravings, overeating, and fat storage – especially around the middle. The body thinks it’s in survival mode and holds onto energy in the form of fat. This isn’t a willpower issue. It’s a biochemical misfire that starts deep within your stress and immune systems.

The immune system plays another key role here. When infections or toxins linger, the immune system can shift into what’s called a Th2 dominant state. In simple terms, this means your body becomes more reactive, releasing more histamine (the same chemical involved in allergies). High histamine can inflame and damage tiny blood vessels – especially those that deliver oxygen and hormones like thyroid to your cells. Over time, this can create fibrosis, or scar-like tissue, that blocks your cells from receiving the signals they need to create energy.

So even if your thyroid levels are technically “normal” on a blood test, the hormone may not be reaching the places it needs to go – like your mitochondria, the tiny power plants in your cells. The result? You feel tired, foggy, cold, and stuck.

This situation – where biology and belief collide – is more than just a health issue. It’s also deeply philosophical. Psychologist Carl Jung described the shadow as the hidden part of ourselves that we avoid or deny. In many ways, our symptoms are the body’s shadow. We try to suppress or ignore them, but they hold essential truths about what’s really going on.

Sociologist Robert Merton also described how people respond when society’s goals become out of reach. Some retreat. Some rebel. Others conform. But a few choose to innovate. That’s what we’re doing here: rethinking the way we approach chronic health conditions. We can’t solve modern health issues using outdated ideas like “eat less, move more.” That thinking belongs to a world before we understood mitochondria, hormones, and immune balance.

At Autonomic Coaching, we take a different approach. We look deeper. We ask why the body is behaving the way it is, and what it’s trying to protect you from. We investigate infections, hormone conversions, nutrient delivery, and cellular communication. And we design strategies that begin not with surface-level diets, but with restoring energy production at the cellular level.

To support your healing journey, we’re offering two free tools to get you started:

1️⃣ Adrenal Restorative Measures Guide – a step-by-step approach to rebuilding your stress and energy system.

Download

2️⃣ What to Do in Hypothyroid States – a simple, accessible document that helps you understand how to support your thyroid, even if labs are “normal.”

    Download

    We encourage you to download them and begin a new chapter of your wellness journey. This isn’t just about getting your energy back – it’s about restoring your ability to respond to life with clarity, vitality, and trust in your body’s wisdom.

    As Leo Tolstoy once said, “Everyone thinks of changing the world, but no one thinks of changing himself.” And as Henry David Thoreau reminded us, “Things do not change; we change.”

    Healing begins when we see our symptoms not as obstacles – but as messages. When we listen, we transform. When we transform, we not only change ourselves – we help shift the health of the world around us.

    The Impact of COVID-19 on Iron Metabolism and Anxiety: A Biochemical Perspective on Catecholamine Metabolism and Neuroinflammation

    Introduction

    The COVID-19 pandemic has had profound effects on both physical and mental health, disrupting key biochemical processes. Among these disruptions, iron metabolism plays a central role in several enzymatic pathways crucial to maintaining biological functions. One often overlooked aspect is the impact of iron deficiency on catecholamine metabolism—small phenolic compounds such as dopamine, norepinephrine, and epinephrine. This article explores how COVID-19-induced reductions in iron levels can lead to the dysregulation of catecholamine metabolism, increased formation of free radicals, and neuroinflammation, all of which contribute to anxiety.

    The Link Between COVID-19 and Iron Levels

    COVID-19 is associated with increased inflammation, leading to the dysregulation of iron homeostasis. This is primarily driven by the overproduction of inflammatory cytokines such as interleukin-6 (IL-6), which induce the release of hepcidin, a hormone that sequesters iron in immune cells, thus reducing its bioavailability for other physiological processes (Ganz and Nemeth, 2012). As iron is crucial for numerous biochemical pathways, including neurotransmitter metabolism and detoxification processes, this deficiency disrupts the normal functioning of key enzymes, contributing to both physical and mental health issues.

    Iron’s Role in Catecholamine Metabolism

    Catecholamines like dopamine, norepinephrine, and epinephrine are essential for stress response, mood regulation, and overall neurological health. The metabolism of these catecholamines involves several iron-dependent enzymes, including monoamine oxidase (MAO) and catechol-O-methyltransferase (COMT), which are responsible for breaking down and detoxifying catecholamines (Zanger and Schwab, 2019). When iron levels are low, these enzymes function less efficiently, leading to the accumulation of unmetabolized catecholamines, which intensifies the body’s stress response and may exacerbate symptoms of anxiety.

    Additionally, catecholamines are prone to auto-oxidation in conditions of low iron availability. This process generates reactive oxygen species (ROS), including semiquinones and quinones, which can form **superoxide radicals and hydrogen peroxide (Xu et al., 2020). The build-up of these free radicals can damage neuronal tissues and contribute to neuroinflammation, a key factor in the development of anxiety and other neuropsychiatric disorders.

    Iron’s Role in Preventing Catecholamine-Induced Free Radical Formation

    In a healthy system, iron plays a crucial role in the neutralization of ROS generated during catecholamine metabolism (Wang et al., 2020). When iron is deficient, the body’s ability to scavenge these free radicals is impaired, leading to oxidative stress. The accumulation of catecholamine-derived ROS can damage brain cells and activate immune cells in the brain, such as microglia, which further exacerbates neuroinflammation (Xu et al., 2020).

    This cascade of oxidative stress and inflammation is strongly associated with anxiety, as chronic neuroinflammation can disrupt neurotransmitter systems, particularly those related to GABA and glutamate. This leads to increased excitatory signals in the brain, contributing to heightened anxiety and other mental health challenges (Patterson and Holahan, 2012). In the context of COVID-19, where iron deficiency and inflammation are common, these mechanisms may underlie the high prevalence of anxiety in both acute and long COVID-19 patients.

    Neuroinflammation and Anxiety

    The link between neuroinflammation and anxiety is well-established, particularly in chronic inflammatory conditions (Patterson and Holahan, 2012). Elevated levels of ROS, combined with impaired catecholamine metabolism, can trigger a pro-inflammatory response in the brain. This activation of microglia and the release of cytokines like IL-1β and TNF-α further aggravates the neuroinflammatory state (Xu et al., 2020). In turn, increased blood-brain barrier permeability allows more peripheral inflammatory mediators to infiltrate the brain, perpetuating a vicious cycle of inflammation and anxiety.

    Thymosin Alpha 1 and Cytokine Storm Mitigation

    One potential therapeutic approach to managing COVID-19-induced inflammation is the use of thymosin alpha 1. This synthetic peptide has been shown to modulate immune responses, reducing the severity of cytokine storms by promoting immune homeostasis and enhancing T-cell function (Zhao et al., 2021). By downregulating pro-inflammatory cytokines like IL-6, thymosin alpha 1 may help prevent further iron depletion and reduce oxidative stress caused by impaired catecholamine metabolism.

    By mitigating the cytokine storm, thymosin alpha 1 may preserve iron homeostasis and prevent the escalation of neuroinflammation and anxiety. In this way, thymosin alpha 1 offers a promising intervention for the mental health issues associated with COVID-19.

    Maraviroc and Modulation of CCL Complexes

    Another potential therapeutic strategy involves the repurposing of maraviroc, a CCR5 antagonist. Maraviroc modulates **CCL (chemokine ligand) complexes, such as CCL2 and CCL5, which are hyperstimulated during severe infections like COVID-19 (Patterson et al., 2020). These chemokines recruit immune cells to inflamed tissues, including the brain, and contribute to neuroinflammation.

    Blocking the interaction between CCR5 and CCL chemokines with maraviroc has been shown to reduce inflammation in the brain and protect the gut-brain axis, a crucial pathway for maintaining neurological health (Patterson et al., 2020). This is particularly important for regulating the **kynurenine pathway, which is activated during inflammation and produces neurotoxic metabolites like quinolinic acid, known to exacerbate anxiety and depression (Parrott et al., 2021).

    By reducing CCL-mediated inflammation, maraviroc may help restore balance to these pathways, reducing oxidative stress and mitigating anxiety in COVID-19 patients.

    Broader Health Implications

    The combined effects of impaired catecholamine metabolism, excessive free radical production, and neuroinflammation may significantly contribute to the development of anxiety in COVID-19 patients. Reduced iron levels lead to the accumulation of catecholamines and an increase in ROS, which amplifies neuroinflammatory responses. Therapeutic interventions such as thymosin alpha 1 and maraviroc offer promising avenues for addressing these underlying biochemical disruptions by reducing inflammation and preserving iron homeostasis.

    Given the well-documented connections between oxidative stress, neuroinflammation, and anxiety, careful management of iron levels and inflammation in COVID-19 patients is essential. Addressing these underlying processes can help mitigate both the physical and mental health challenges posed by the virus.

    Conclusion

    Iron plays a critical role in catecholamine metabolism, and its deficiency in COVID-19 patients can lead to the dysregulation of catecholamine pathways, increased free radical production, and neuroinflammation. These disruptions are strongly linked to the development of anxiety. Therapeutic strategies that address both iron homeostasis and inflammation, such as thymosin alpha 1 and maraviroc, offer promising avenues for reducing neuroinflammation and improving mental health outcomes in COVID-19 patients. Future research should explore these treatments in larger clinical trials to validate their efficacy in mitigating neuroinflammation-related anxiety.
