About seventy-five percent of Americans take some kind of dietary supplement. But do they work? A new study sheds light on whether supplements for the heart are worth your time and money.
Researchers reviewed data from hundreds of clinical trials involving almost one million people and found only two of the 16 popular supplements had a noticeable effect on heart outcomes.
Folic acid and omega-three fatty acids showed modest benefits. But vitamins A, B, C, E, beta carotene, iron, antioxidants, and multi-vitamins showed no benefits. And taking calcium with vitamin D increased the risk of stroke.
“We found those who were taking supplements, calcium supplements compared to non-supplement users were 22 percent more likely to have new development of calcium on heart arteries on the second cat scans- ten years apart,” Erin Michos, MD, MHS, Cardiologist at Johns Hopkins University School of Medicine, said.
