Evidence Rating Table

CategoryCognitive EvidenceUse Case
Omega-3Mixed for cognition; stronger for dietary adequacy and cardiovascular contextUseful if fish intake is low or EPA/DHA target is not met.
CreatineMixed but promising for memory/stress/older adultsMore defensible than random nootropic blends.
Vitamin D3Correct deficiency; not independently cognitive in SYNERGICUse for deficiency/status, not as a brain booster.

Scientific References

  1. FINGER multidomain lifestyle RCT. A 2-year multidomain intervention combining diet, exercise, cognitive training and vascular-risk monitoring helped maintain or improve cognitive performance in at-risk older adults. Study link: 25771249
  2. SYNERGIC Study in mild cognitive impairment. Aerobic-resistance exercise improved cognition versus control, cognitive training added benefit, while vitamin D did not show an independent cognitive effect in this trial. Study link: 37471089
  3. Creatine and cognition systematic review. Creatine has plausible brain-energy mechanisms, but cognitive benefits are mixed and may be more relevant under stress, sleep deprivation, aging or low dietary creatine intake. Study link: 39070254
  4. Creatine memory meta-analysis. A meta-analysis of randomized trials reported a possible memory benefit, with stronger practical interest in older adults; dosing and responder profiles remain uncertain. Study link: DOI: 10.1093/nutrit/nuac064
  5. Long-chain omega-3 and cognitive decline meta-analysis. Omega-3 supplementation evidence for preventing cognitive decline in non-demented adults is mixed; dietary fish intake and cardiovascular context may matter more than generic brain claims. Study link: DOI: 10.1093/nutrit/nuz073
