What Are Dietary Supplements?
Dietary supplements are the category of products intended to be added to the diet as a food for the missing or insufficient amount of one or more essential nutrients not supplied by a person’s regular diet. Supplements can be taken in nearly every form, such as tablets, capsules, powder, or liquids. Where quality controls are tight, the best supplements are those that provide evidence-based assistance in health support.
