A dietary supplement is a product intended to add nutritional value to your
diet. Supplements can contain vitamins, minerals, herbs, amino acids, enzymes,
probiotics, or other substances. They come in many forms — pills, capsules,
tablets, powders, liquids, and gummies — and are designed to supplement (not
replace) a balanced diet. While they are not medicines, quality supplements backed by scientific
research can play a meaningful role in supporting overall health, filling nutritional gaps, and
optimizing specific body functions.
In the U.S., supplements are regulated by the FDA under the Dietary Supplement Health and
Education Act (DSHEA) of 1994. Always consult a healthcare professional before starting any
new supplement.
