Nature’s Way Activated Charcoal (from Indian Hardwood) is one of the finest natural adsorbent agents known. Each particle contains many small chambers and cavities that bind-up unwanted material or gas. Activated Charcoal is commonly used to adsorb digestive gas. It also protects the body from overdosing on harmful toxic substances. Due to its large surface area, activated charcoal has high adsorption properties, meaning that it keeps certain substances from being absorbed in the body’s gastro-intestinal tract.
