Our food-grade Activated Charcoal is produced from coconuts which have been highly purified with steam to remove any contaminants for use as a food-grade active ingredient. Our Activated Charcoal Powder is a finely reduced powder (5-10 microns), which presents a huge surface area for the absorption of unwanted substances. When taken orally or used on teeth or skin it works like a sponge to soak up contaminants.
