Talc is a naturally occurring mineral composed mainly of magnesium, silicon, and oxygen. In the supplement and pharmaceutical industries, it is commonly used as a glidant—a substance that helps powders flow smoothly during the manufacturing process, ensuring even filling and consistent tablet formation.

In addition to improving production efficiency, talc also acts as an anti-caking agent and helps prevent ingredients from sticking to machinery. Though it does not provide nutritional benefits, talc plays a key functional role in maintaining the quality, texture, and uniformity of tablets and capsules. When used in regulated, purified forms, talc is considered safe and effective for use in health and wellness products.
