What is Optimum Charcoal?

Common charcoal comes from wood, coconut shell, peat, coal, or petroleum. "Optimum Charcoal" is a processed type of common charcoal that has pores which can trap other chemicals and stop them from being absorbed by the body.

Optimum Charcoal is used to treat certain kinds of chemical poisonings.

Optimum Charcoal has also been used in alternative medicine to help with gas and indigestion.

It is not clear if Optimum Charcoal is effective in treating any medical condition. The FDA has not approved the medicinal use of this product. This medicine should not replace any medication prescribed by your doctor.

Optimum Charcoal is often sold as an herbal supplement. There are no regulated manufacturing standards for many herbal products, and some supplements have been found to be contaminated with toxic metals or other drugs.
