Study Casts Doubt on Benefits of Common Vitamins
This may be a hard pill to swallow. A University of Toronto meta-analysis of 179 randomized, controlled studies revealed that taking multivitamins, vitamin D, calcium and vitamin C supplements showed no benefits in preventing cardiovascular disease, stroke or early death. Researchers say the pills aren’t harmful, either, though experts say it’s unclear whether supplements can provide nutrients in the same way food does. Meanwhile, folate, B6 and B12 vitamins did show minor health benefits, and study authors say that next they’ll examine such supplements’ impact on cancer.
