Natures Sunshine Activated Charcoal is highly adsorbent, which means particles stick to the outside of the structure, rather than being sucked inside as with "absorbent" materials. Charcoal is often used to support the body's cleansing and detoxification mechanisms as it helps bind toxins in the digestive tract. It may also be used to support the the expulsion of intestinal gas, ingestested poisons and harmful foodborne substances.
