Brain Fog
Shopping & Supplement List

Root cause chain: Gut permeability → LPS crosses blood-brain barrier → neuroinflammation → neurotransmitter disruption → cognitive dysfunction

Every item is selected for its specific role in the biological chain driving this condition. This is not a generic health food list.

✓ Foods to prioritise
Blueberries daily
Anthocyanins cross the blood-brain barrier and reduce neuroinflammation directly. Most studied food for cognitive protection.
Wild salmon
DHA for brain cell membrane structure. EPA reduces neuroinflammatory cytokines. The most important food for brain health.
Eggs
Choline is required for acetylcholine synthesis — the neurotransmitter of memory and learning. One of the most deficient nutrients in the modern diet.
Dark leafy greens
Folate supports methylation — the process producing dopamine and serotonin from their precursors.
Walnuts
Highest ALA omega-3 of any nut. Polyphenols reduce neuroinflammation. Contain melatonin and serotonin precursors.
Extra virgin olive oil
Oleocanthal reduces beta-amyloid accumulation in brain tissue — the protein linked to Alzheimer's. Daily consumption is the most studied dietary intervention for brain protection.
Bone broth
Repairs gut lining — reducing the LPS that crosses the blood-brain barrier and drives the neuroinflammation behind brain fog.
Avocado
Lutein supports cognitive function. Healthy fat improves absorption of fat-soluble brain nutrients.
✕ Foods to eliminate or reduce
Sugar
Creates the glucose-crash cycle that directly starves the prefrontal cortex. Feeds gut dysbiosis that produces LPS driving neuroinflammation.
Seed oils
Omega-6 dominant — shift the brain's fatty acid composition toward inflammatory, impair neuronal membrane function.
Alcohol
Destroys hippocampal neurons, impairs glymphatic clearance, depletes B vitamins required for neurotransmitter synthesis.
Gluten (if MTHFR positive)
Gliadin triggers zonulin release, increases gut permeability, and elevates LPS — directly driving neuroinflammation.
Ultra-processed foods
Emulsifiers disrupt gut microbiome diversity and increase permeability — amplifying the gut-to-brain inflammation pathway.
Late eating
Disrupts sleep architecture and reduces glymphatic clearance — the brain's overnight waste removal system.
⚗ Supplement protocol
Omega-3 DHA focus
Structural fat of brain cell membranes. Low DHA is the most common nutritional driver of brain fog.
2g DHA daily with food
Magnesium Threonate
Only form crossing the blood-brain barrier. Increases synaptic density and reduces neuroinflammation.
200mg before sleep
Phosphatidylserine
Brain cell membrane phospholipid. Improves memory, processing speed, and executive function.
300mg daily with breakfast
Lion's Mane Mushroom
Stimulates NGF — drives neuron repair and myelin production.
500-1000mg daily with food
B Complex (methylated)
Methylcobalamin B12 and methylfolate support neurotransmitter synthesis. Essential if MTHFR positive.
B12 1000mcg + folate 400mcg daily
Bacopa Monnieri
Adaptogen that reduces neuroinflammation and improves memory consolidation. Cumulative — 8-12 weeks.
300mg daily with fat-containing meal
Acetyl-L-Carnitine
Crosses blood-brain barrier. Supports mitochondrial ATP in neurons and acetylcholine synthesis.
500mg with breakfast
