Omega 3 Supplements Not An Effective Treatment For Major Depressive Disorder

A British review of data from 26 randomized clinical trials involving 1,458 participants found little evidence that omega-3 fatty acid supplements effectively treated major depressive disorder. Omega 3s, thought to be essential for good health, are naturally found in fatty fish and some nuts and seeds. People treated with omega 3 fatty acids reported lower symptom scores than people with a placebo pill, the effect was small. And important limitations undermined researcher confidence in the results. The researchers acknowledged that most of the studies were small and of low quality.
