Omega-3 Supplements for Heart Disease
According to the 2007 National Health Interview Survey, which included a comprehensive survey on the use of complementary health practices by Americans, fish oil/omega-3/DHA supplements are the natural product (excluding vitamins and minerals) most commonly taken by adults, and the second most commonly taken by children.
There has been a substantial amount of research on omega-3 supplements and heart disease. Experts agree that fish rich in omega-3 fatty acids should be included in a heart-healthy diet. However, omega-3s in supplement form have not been shown to protect against heart disease.
Omega-3s are being extensively studied for other conditions, such as rheumatoid arthritis and cognitive decline. Current evidence-based information is available from NCCAM at nccam.nih.gov/health/omega3.
