Brain Nutrition Evidence Library
This page gathers research-informed information about nutrients and supplements that may support brain health, the gut-brain axis, nervous system function, and memory. Our goal is to provide clear evidence-based summaries for educational use.
Supplements are optional tools that sit alongside core foundations like restorative sleep, movement, therapy, relationships, and medical care. They are intended to complement, not replace, these essential pillars of well-being.
Each row in our library identifies a specific ingredient and what it may support, accompanied by a research DOI and example product types. You will also find an iHerb link to view professional-grade options.

Omega-3 DHA/EPA
May provide modest cognitive support, especially when dietary intake is low.
Ingredient
Potential Benefit
Research DOI
Example Brands
Bacopa monnieri
May support memory and learning in some adults; results may vary.
Creatine monohydrate
May support memory, attention and processing speed, especially under stress or during ageing.
B6, B12, Folate
May help people with raised homocysteine or mild cognitive impairment; benefits are not universal.
Lion’s Mane
Early research; small studies show emerging evidence with mixed findings.
Gut-Brain Axis & Microbiome Resilience
Research increasingly highlights the bidirectional communication between the enteric nervous system and the brain. Supporting microbial balance is a key pillar in managing cognitive fatigue and emotional regulation.
Ingredient
Probiotics / psychobiotics
May support mood and stress via the gut-brain axis; effects vary per person.

Nervous System & Resilience
The following elements are studied for their role in autonomic regulation and stress buffering. Evidence is emerging and response variability is common.
Ingredient
Potential Benefit
Research DOI
Example Brands
GABA support formulas
sometimes used for calming support; evidence and quality vary (cautious wording advised)
Magnesium glycinate / citrate
may support sleep and nervous system regulation; evidence is promising but variable
Ashwagandha
may help with stress and cortisol regulation in some adults
Saffron extract
emerging evidence for mood and wellbeing
Advanced Cognitive Enrichment
Optimizing memory requires a multifaceted approach where clinical interventions, sleep hygiene, and specialized nutrients intersect. This section explores unique botanical and compound-based additions that specifically target mental clarity.
Ingredient
Potential Benefit
Research DOI
Example Brands
Phosphatidyl.
Phospholipid essential for cell membrane integrity; may improve retrieval and cognitive fluidity in older adults.
Cordyceps
Known to improve learning and memory, potentially helping to alleviate cognitive decline
Alpha-GPC Formula
A potent choline source that crosses the blood-brain barrier; studied for its role in acetylcholine synthesis and recall.
Huperzine A (Club Moss)
Acts as an acetylcholinesterase inhibitor; early research indicates it may slow memory decline in specific groups.
L-Theanine
When paired with caffeine, it may refine attention and word recognition by modulating alpha brain wave activity.
