Many of the people we see in clinic present with complex autoimmune pictures, fatigue and multi‑system symptoms – and, beneath the surface, a long history of trauma or chronic stress. Understanding how this shapes the HPA axis, mitochondria and immune signalling can help us choose more precise, trauma‑informed interventions rather than just “add more supplements”.
How Trauma Rewires the HPA Axis and Autonomic Nervous System
Trauma – particularly in childhood – chronically activates the HPA axis, creating sympathetic dominance. Over time, this persistent over‑signalling can reprogram both the nervous system and the mitochondria. The resulting stress may trigger a cell danger response, in which mitochondria produce less energy and shift into survival mode.
The HPA axis is the body's core stress‑response system. It links the hypothalamus and pituitary in the brain with the adrenal glands on the kidneys to control cortisol output. When stress is perceived, brain signals trigger cortisol release to help you cope, after which feedback loops are meant to turn the system off again. With chronic stress or unresolved trauma, this self‑regulation falters, leading to anxiety, fatigue, poor sleep, and difficulty calming down.
The Cell Danger Response and Mitochondrial Re‑Programming
The cell danger response represents the cellular side of the same story. Under ongoing threat, mitochondria shift from an energy‑producing “thrive and repair” mode to a protective “defence” mode. This cellular state can mirror and reinforce an overactive HPA axis, leaving both the nervous system and the cells stuck in protection rather than safety and regulation.
Together, these patterns suggest that healing from trauma means slowly showing both the nervous system and the body's cells that life is safe again. By sending the body repeated “safety signals” – through gentle body‑based practices, simple breathing exercises, ways of calming the vagus nerve, and good nutrition – the main stress system (the HPA axis) can gradually come out of constant emergency mode. When this happens, our cells can shift back into a higher‑energy, repair‑focused state, and it often becomes easier to rest, feel steady, and connect with others.
Nervous System Regulation, Somatic Work and Neural Therapy
Supportive modalities include nervous system regulation, somatic work, breathing exercises, meditation, humming, cold exposure, vagal stimulation, neural therapy, and nutritional support. Most of the methods above are fairly self‑explanatory, but neural therapy is more specialised.
Neural therapy is a medical technique where a practitioner injects very small amounts of local anaesthetic (such as procaine) into specific points like scars, nerves, or autonomic ganglia. The aim is to “reset” dysfunctional nerve signalling in the autonomic nervous system, which can help reduce chronic pain and calm long‑standing stress patterns in the body. This is done only by trained clinicians.
Nutritional Support for Trauma‑Related Autoimmune Patterns
B‑Complex and Thiamine (B1) for Vagus Nerve Signalling
B‑complex and thiamine (B1) are key for vagus nerve signalling and energy. I use Objective Nutrients B Complex plus their high‑dose B1 (Benfotiamine and/or TTFD), and I also like Life Extension Benfotiamine and Vitality Pro Benfotiamine.
Choline, Acetylcholine Support and Vagal Tone
Because acetylcholine is the main neurotransmitter of the vagus nerve, I often recommend BodyBio Phospholipid Complex, Vitality Pro Alpha GPC and Jarrow Formulas CDP‑Choline. These can be helpful where vagal tone, membrane integrity and autonomic balance are part of the therapeutic focus.
Magnesium for Nerve Relaxation and ATP
Magnesium is essential for nerve transmission and parasympathetic “calm”; magnesium glycinate is my go‑to form, and we stock several high‑quality brands in this form. Magnesium is also the main mineral directly required for ATP because ATP works in the body as Mg‑ATP. Other important minerals that support ATP production and energy metabolism include iron, copper, zinc, manganese, chromium, selenium, and iodine.
Essential Fatty Acids and Membrane Integrity
Essential fatty acids and membranes are central for neuronal membrane structure and vagal anti‑inflammatory signalling. I like omega‑3‑rich fish or krill oil, or “parent essential oil” blends from brands such as BodyBio and Yes.
GABAergic and Calming Amino Acids
GABAergic / calming amino acids (e.g. L‑theanine, taurine, glycine) may help shift the system towards parasympathetic dominance and reduce stress reactivity. I use Life Extension, Vital Nutrients, Orthoplex and Quicksilver.
Antioxidants and Polyphenols
Antioxidants and polyphenols – such as vitamin C, vitamin E, curcumin, and resveratrol – play a key role in reducing oxidative stress around nerves and supporting healthy neural signalling. I use Livon Labs and Quicksilver for vitamin C; Life Extension, Researched Nutritionals, and Designs for Health for vitamin E; Apex, Integrative Therapeutics, and Designs for Health for curcumin; and formulations from Apex, Moss, and Vital Nutrients for resveratrol.
Additional Mitochondrial Support
CoQ10 (ubiquinol) serves as a key electron carrier in the mitochondrial electron transport chain and acts as a strong antioxidant, helping protect mitochondrial membranes and DNA from oxidative damage. I recommend ubiquinol CoQ10 from Life Extension, Pharma Nord, and Researched Nutritionals.
Niacin and NAD⁺ Precursors (NR, NMN)
Niacin (vitamin B3), as well as NR (nicotinamide riboside) and NMN (nicotinamide mononucleotide), all contribute to building and maintaining NAD⁺ pools, which are essential for mitochondrial energy production, redox reactions, DNA repair, and sirtuin activity. For NAD⁺ support, I recommend Quicksilver products; for NR, NAD Cell Excel by New Roots Herbal; for NMN, Purevitalis; and for niacin, Seeking Health.
PQQ and Combination Formulas
PQQ supports mitochondrial biogenesis (the formation of new mitochondria) and has redox‑modulating and antioxidant effects, which can enhance mitochondrial efficiency and resilience. I recommend PQQ from Designs for Health and Seeking Health.
Microbiome–Vagus–Inflammation Axis in Trauma and Autoimmunity
Mitochondrial ATP nutrient combinations can be extremely useful in clinic. I recommend comprehensive mitochondrial formulations such as BC‑ATP by Cellcore Biosciences and ATP 360 by Researched Nutritionals. These combination products typically include multiple mitochondrial cofactors (e.g., B vitamins, CoQ10, carnitine, antioxidants, phospholipids) to support ATP production at several steps, stabilize mitochondrial membranes, and reduce oxidative stress in a more integrated way than single agents.
Targeted Probiotic and Postbiotic Interventions
The microbiome–vagus–inflammation link is highly relevant in trauma‑associated autoimmune pictures. Certain Lactobacillus and Bifidobacterium strains (e.g. L. rhamnosus GG, B. longum 1714) can modulate vagal nerve activity and lower cortisol.
I like Essential‑Biotic L. Rhamnosus GG by Allergy Research Group and ZenBiome Cope by Microbiome Labs, which has B. Longum 1714. I also like MegaSporeBiotic by Microbiome Labs.
Polyphenol‑Rich Prebiotics
Polyphenol‑rich prebiotics are an important piece in reducing gut‑driven inflammation that maintains HPA activation.
I like MegaPre by Microbiome Labs.
Gentle Cellular and Environmental Modulation
Sunlight and Circadian Entrainment
Sunlight and circadian entrainment are underrated tools in trauma‑informed, autoimmune‑focused care. Morning light and regular sleep‑wake timing stabilise the HPA rhythm.
Movement Therapies
Movement therapies – yoga, qigong, or slow walking – can re‑synchronise autonomic patterns with respiration. For many clients this also provides a safe container for interoception and somatic processing.
Grounding and Infrared Exposure
Grounding and infrared exposure can be used as gentle cellular and environmental modulation. Light physical contact with natural surfaces or mild heat therapy may reduce sympathetic overdrive.
Bringing It Together in Practice
For the nutritional therapist, this framework allows us to view autoimmune disease through a trauma‑informed, systems‑biology lens. We can address HPA dysregulation, mitochondrial function, vagal tone, microbiome balance and environmental inputs, while respecting each client’s trauma history and pacing.
