Solaray Activated Charcoal is derived from a special high-quality grade charcoal. Charcoal is made from wood or other natural materials by heating them in an airless environment. Charcoal used for health conditions is usually “activated” to make it a very fine powder which increases its effectiveness. Activated Charcoal can chemically attach or adsorb to a variety of particles and gases which makes it ideal for removing potentially toxic substances from the digestive tract. Activated Charcoal is not absorbed into the body so it carries adsorbed substances out of the body in the feces.
