Omega-3 pills don’t boost memory in new brain-health study

A randomized, double-blind trial found that high-dose omega-3 algae supplements did not improve memory or cognition in adults at risk for dementia, even though blood and cerebrospinal fluid showed higher omega-3 levels. The researchers say benefits come from overall healthy lifestyle choices—exercise, sleep, and a Mediterranean-style diet with fatty fish—rather than supplements alone.
