The Claim
Daily supplementation with 1 gram of marine omega-3 fatty acids (460 mg EPA and 380 mg DHA) for a median of 5.3 years does not significantly reduce the incidence of major cardiovascular events (myocardial infarction, stroke, or cardiovascular death) in healthy adults aged 50 and older.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking a daily omega-3 supplement for about five years doesn't seem to lower the risk of heart attacks, strokes, or heart-related death in healthy people over 50.
See the scientific wording
Daily supplementation with 1 gram of marine omega-3 fatty acids (460 mg EPA and 380 mg DHA) for a median of 5.3 years does not significantly reduce the incidence of major cardiovascular events (myocardial infarction, stroke, or cardiovascular death) in healthy adults aged 50 and older, based on a hazard ratio of 0.92 (95% CI: 0.80–1.06; p=0.24) from a large randomized trial involving 25,871 participants.
What the research says
1 studyStudy: Marine Omega-3 Fatty Acids and Prevention of Vascular Disease and Cancer
This big study gave people a daily fish oil pill for over five years and found it didn’t lower their risk of heart attacks, strokes, or dying from heart problems compared to those who took a sugar pill.
