Neuroinflammation
1. Root Cause Overview
Neuroinflammation is the activation of the brain's innate immune system — primarily microglia and astrocytes — in response to injury, infection, toxins, metabolic dysfunction, or peripheral inflammatory signals. While acute neuroinflammation is protective, chronic neuroinflammation drives neurodegeneration, mood disorders, cognitive decline, and conditions including Alzheimer's disease, Parkinson's disease, depression, anxiety, and autism spectrum disorder. Key drivers include gut dysbiosis (gut-brain axis), blood-brain barrier disruption, chronic systemic inflammation, toxin burden, and metabolic dysfunction.
2. Common Signs & Symptoms
- Brain fog, cognitive slowing, poor concentration
- Memory impairment (short-term > long-term)
- Depression and/or anxiety
- Fatigue disproportionate to activity
- Headaches (often diffuse, pressure-type)
- Sensory sensitivities (light, sound, smell)
- Sleep disturbances (difficulty initiating or maintaining sleep)
- Mood lability, irritability
- Peripheral neuropathy symptoms
- Elevated inflammatory markers on standard or functional labs
3. Labs to Consider
hs-CRP, ESR, fasting glucose/insulin, B12/MMA, vitamin D, thyroid panel, iron/ferritin; neurologic referral for red-flag symptoms.
Choose the lab option based on what you want to assess within this root cause.

4. Clinical Priorities
Evaluate for multiple potential contributors to neuroinflammation, such as gut dysfunction, metabolic imbalance, thyroid issues, vitamin D insufficiency, neurotoxic exposures, chronic infection, sleep disruption, and unresolved psychological stress. Use the clinical picture and testing to prioritise which drivers appear most relevant, while supporting sleep and glymphatic clearance as part of the overall strategy.
Where to Start: Top 2 Supplements
DHA is the primary structural fatty acid of neuronal membranes and the most evidence-backed anti-neuroinflammatory nutrient. Reduces microglial activation, resolves neuroinflammation via specialised pro-resolving mediators (SPMs), and improves cognitive function. Start here for any neuroinflammatory condition.
The most studied botanical for neuroinflammation. Crosses the blood-brain barrier (high-bioavailability forms), inhibits NF-κB in microglia, upregulates BDNF, and has demonstrated cognitive benefit in RCTs. Synergistic with omega-3 for combined resolution of neuroinflammation.
5. Diet Strategy
Adopt a brain-protective dietary pattern: Mediterranean or MIND diet. Emphasise fatty fish (DHA/EPA), blueberries (anthocyanins), leafy greens (folate, vitamin K), nuts (vitamin E, polyphenols), olive oil (oleocanthal — natural COX inhibitor), and turmeric. Eliminate ultra-processed foods, refined sugars, trans fats, and alcohol. Consider a low-glycaemic diet to reduce neuroinflammatory insulin spikes. Ensure adequate choline (eggs, liver) for acetylcholine synthesis.
6. Lifestyle Strategy
Regular aerobic exercise is the most potent anti-neuroinflammatory intervention — increases BDNF, reduces microglial activation, and improves glymphatic clearance. Prioritise 7–9 hours of quality sleep (glymphatic system clears neuroinflammatory waste during deep sleep). Mindfulness meditation reduces neuroinflammatory markers. Minimise screen time and electromagnetic exposure. Social connection and cognitive engagement are neuroprotective.
7. Supplement Strategy
Full supplement list below. See Section 4 (Clinical Priorities) for the recommended Top 2 starting supplements. Add additional supplements based on lab results and clinical response at 4–6 week reassessment.
| Supplement | Dosage | Indication | Evidence | Key Results | Example |
|---|---|---|---|---|---|
| Omega-3 Fatty Acids (DHA-dominant) [1] Fish burp; anticoagulant interaction at high doses | 2–4 g/day (DHA:EPA ratio ≥2:1 for brain) | Neuroinflammation resolution; microglial modulation; DHA structural component of neuronal membranes | RCT and meta-analysis | Reduced neuroinflammatory markers; improved cognitive function and mood; reduced microglial activation | Nordic Naturals Ultimate Omega |
| Curcumin (BCM-95 or CurcuWIN® — high bioavailability) [2] Mild GI upset; avoid in gallstone disease | 500–1,000 mg/day | NF-κB inhibition; microglial modulation; BDNF upregulation; amyloid inhibition | RCT and mechanistic studies | Reduced neuroinflammatory markers; improved memory and attention in older adults; BDNF upregulation | Nutricology CurcuWIN 500 |
| Lion's Mane Mushroom (Hericium erinaceus) [3] Generally well tolerated; rare GI upset; caution in mushroom allergy | 500–3,000 mg/day standardised extract | Nerve growth factor (NGF) stimulation; neuroregeneration; cognitive support | RCT (double-blind, placebo-controlled) | Significantly improved cognitive function scores in mild cognitive impairment; increased NGF expression | Host Defense Lion's Mane |
| Phosphatidylserine [4] Generally well tolerated; mild GI upset; anticoagulant interaction at high doses | 300–400 mg/day | Neuronal membrane integrity; cortisol modulation; cognitive function | RCT | Improved memory, learning, and cognitive function in older adults with memory complaints; reduced cortisol response | Jarrow Formulas PS100 |
| Magnesium L-Threonate [5] Loose stools at high doses; generally well tolerated | 1,500–2,000 mg/day (providing ~144 mg elemental Mg) | Brain-penetrant magnesium form; synaptic plasticity; NMDA receptor modulation; anxiety and sleep | RCT | Improved cognitive function and memory in older adults; increased brain magnesium levels; reduced anxiety | Life Extension Neuro-Mag |
8. Safety Notes
Neurological red flags (sudden cognitive decline, focal neurological deficits, seizures, severe headache) require immediate medical referral. Do not use supplements as a substitute for neurological evaluation. High-dose omega-3 requires monitoring in patients on anticoagulants. Lion's Mane is contraindicated in mushroom allergy. Always address the upstream drivers (gut health, metabolic dysfunction, toxin burden) concurrently with neuroinflammation support.
