Micronutrients & recovery
Supplementation with 1 g/day of marine n-3 fatty acids (containing 840 mg EPA/DHA) does not reduce the incidence of major cardiovascular events or invasive cancer in a general population at usual risk.
Taking 1 gram of fish oil daily (providing 840mg EPA/DHA) does not significantly lower your risk of heart attacks, strokes, or cancer if you are otherwise at average risk. Focus on proven lifestyle factors instead.
StrongRefutesHIGH confidence
Supplementation with n−3 fatty acids did not result in a lower incidence of major cardiovascular events or cancer than placebo.
Why this rating
Large-scale, randomized, double-blind, placebo-controlled trial (VITAL) with 25,871 participants and median follow-up of 5.3 years.
