Dietary supplements are enormously popular in the United States. A new federal survey found that a majority of Americans are taking them, with many consuming multiple kinds on a regular basis. And yet, supplements are shrouded in misconceptions. Supplements have less oversight than pharmaceutical drugs and are regulated differently. While people may take them to be healthier, we often don’t think about possible side effects or interactions. We also assume we know what we’re getting. Today, host Martine Powers talks with the Post’s Well+Being columnist, Anahad O’Connor, about how to be smarter about the supplements we take to improve our health. Today’s show was produced by Elana Gordon. It was edited by Lucy Perkins and mixed by Sean Carter. Subscribe to The Washington Post here.
