What Are Dietary Supplements?
A plain-language introduction to dietary supplements — what they are, how they're regulated, and when they might be useful.
A working definition
A dietary supplement is a product intended to add nutrients to the diet. It can contain vitamins, minerals, herbs, amino acids, enzymes or other ingredients, and comes in forms like capsules, tablets, powders, liquids and gummies.
Supplements complement, not replace, food
A well-planned diet should remain the foundation. Supplements can help fill specific gaps — for instance, nutrients that are hard to get enough of from food alone — but they don't compensate for a poor overall diet.
“Supplements are tools, not shortcuts. They work best on top of solid sleep, food and movement habits.”
Regulation and what it means
Supplements are generally regulated differently from medicines in most markets, meaning companies bear much of the responsibility for safety and accurate labelling. This is exactly why label literacy and third-party testing matter so much when you shop.
