Dietary Supplements Definition: Key Concepts and Regulatory Terms
Dietary supplements are products designed to improve health and wellness by providing nutrients that may be missing or insufficient in a person's regular diet. They are not intended to replace food or act as medicines, but rather to supplement the diet, especially when there is a nutritional imbalance or deficiency Hassan2020Mishra2020Kalidindi2024. According to the US Food and Drug Administration (FDA) and the Dietary Supplement Health and Education Act, a dietary supplement is a product (other than tobacco) intended to supplement the diet and contains one or more dietary ingredients such as vitamins, minerals, herbs or botanicals, amino acids, or other substances that increase total dietary intake .
Supplements are typically taken orally and come in various forms, including pills, capsules, tablets, powders, liquids, gummies, teas, and energy bars Hamlaoui2023Mishra2020Alsudani2025+1 MORE. They are regulated differently from medicines and are generally considered as special foods rather than drugs Hamlaoui2023Wong2016.
