🧠Your brain runs on omega-3s. A systematic review of 9 clinical trials (1,319 participants) confirms what researchers have long suspected:
✅ Better learning & memory
✅ Improved cognitive wellbeing
✅ Increased blood flow to the brain
The key players?
DHA, EPA, and ALA — the omega-3 fatty acids found in fish, walnuts, flaxseeds, and more. DHA alone is the dominant fat in the human brain.
Older adults, those living alone, and people with low omega-3 diets may benefit most from supplementation — but the researchers' top recommendation? Get it through food first.
