They say: Omega-3 fish oil supplements may lower heart attack risk

Taking omega-3 fish oil supplements every day may reduce the risk of heart attack and other cardiovascular events, including death. However, it may not protect against stroke.

These were the findings of an updated meta-analysis that pooled data from 13 trials involving more than 125,000 participants.

Previously pooled analyses have yielded mixed results on whether daily omega-3 fish oil supplements can reduce heart risks.

However, the new study included data from three large scale recently completed trials, which increased the number of participants by 64%.

The inclusion of the new data had a “substantial influence on the available evidence,” note the authors in a recent Journal of the American Heart Association paper about the study.

“This meta-analysis,” says first study author Yang Hu, Ph.D., of the Department of Nutrition at Harvard T.H. Chan School of Public Health in Boston, MA, “provides the most up-to-date evidence regarding the effects of omega-3 supplementation on risk of multiple [cardiovascular disease] outcomes.”

An 8% reduction in risk of heart attack and other cardiovascular events may seem modest to individuals.
