Activated charcoal is charcoal that has been treated with heat to increase its adsorptive properties. It has millions of tiny pores that bind, trap and remove toxins. It can adsorb thousands of times its own weight. Just a gram of activated charcoal can have an effective surface area in excess of 500m2. That’s why just a tiny bit of our ultra fine medicinal grade activated charcoal can go a long way. Our activated coconut shell charcoal is completely eco-friendly too!
