Dietary supplements are regulated by the US Food and Drug Administration (FDA) as food, not as drugs. However, many dietary supplements contain ingredients that have strong biological effects and that may conflict with a medicine you are taking or a medical condition you may have. Products containing hidden drugs are also sometimes falsely marketed as dietary supplements, putting consumers at even greater risk. For these reasons, it is important to consult with a health-care professional before using any dietary supplement. Read these Consumer Updates to learn more.
