Best Supplements for Brain Health

Supporting cognitive function now and protecting it later

Brain health supplements fall into two categories: those that support daily cognitive function and those focused on long-term brain health. The best approach addresses both.

Strong Evidence

Effective Dose1-2g combined EPA/DHA daily, with at least 500mg DHA
Time to Effect4-8 weeks for noticeable effects

DHA is a structural component of brain tissue. Low levels are linked to cognitive decline. Studies show benefits for memory and processing speed, especially in those with low fish intake.

Best for:Long-term brain healthThose who don't eat fishMemory support
Creatine7.5/10
Effective Dose3-5g daily
Time to Effect2-4 weeks

Your brain uses creatine for energy. Supplementation may improve short-term memory and reasoning, especially under stress or sleep deprivation. Vegetarians often see bigger benefits.

Beyond Supplements

  • Sleep is the most important factor for cognitive function
  • Exercise increases brain-derived neurotrophic factor (BDNF)
  • Social connection and mental stimulation matter for long-term brain health
  • Managing cardiovascular risk factors protects brain health

Note: These supplements support brain health but cannot treat or prevent neurological conditions. Cognitive concerns should be evaluated by a healthcare provider.
