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
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.
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.
Promising but Limited Evidence
Lion's mane may stimulate nerve growth factor (NGF) production. Animal studies are promising for memory and cognitive function. Human studies are limited but encouraging.
Phosphatidylserine is a phospholipid important for cell membranes. Some studies show modest benefits for memory in older adults. Evidence is mixed.
Traditional herb with studies showing modest memory benefits. Takes several weeks to work. May cause digestive upset in some people.
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.
