Researchers have revealed that common pills, like vitamin C capsules, have not been proven to provide health benefits while some could even increase the risk of death. Instead, they suggest people are better off getting their nutrients from eating a healthy diet of fruits and vegetables.
Published in the Journal of the American College of Cardiology, researchers from St Michael’s Hospital and the University of Toronto reviewed the most common supplements taken by the general population including A, B1, B2, B3 (niacin), B6, B9 (folic acid), C, D and E. Also studied were the minerals beta-carotene, calcium, iron, zinc, magnesium, and selenium.
It found that while multivitamins, vitamin D, calcium and vitamin C showed no harm, they also showed no benefit in the prevention of cardiovascular disease, heart attacks, strokes or premature death. They also discovered that some, including niacin and antioxidants, showed signs they could actually be harmful as they showed a very small increased risk of death from any cause.
One of the supplements, folic acid, was found to have some positive effects though and was proven to help reduce the risk of heart disease or stroke. “We were surprised to find so few positive effects of the most common supplements that people consume,” said.
