A supplement is a concentrated source of specific vitamins, minerals, herbs, amino acids, or other nutrients that are typically taken in addition to one's regular diet to fill nutritional gaps, support overall health, or address specific health concerns.

Supplements come in various forms, including pills, capsules, powders, and liquids, and are intended to complement a person's diet by providing essential nutrients that may be lacking, with the goal of promoting well-being, preventing deficiencies, or achieving specific health and wellness objectives. It's important to use supplements in moderation and under the guidance of a healthcare professional to ensure their safe and effective use.
