Dietary supplements contain ingredients like vitamins, minerals, herbs and other botanicals. They come in various forms such as tablets, capsules, and powders. A dietary supplement is defined as a product intended to supplement the diet that contains one or more dietary ingredients. Supplements can provide benefits like obtaining vital substances, reducing disease risk, and not replacing complete meals. However, risks include supplements interacting harmfully with other supplements, medications, or being overused. Supplement labels must include information like product name, quantity, and manufacturer but are not required to be approved by the FDA for safety and effectiveness.
