What is USP Activated Charcoal Powder?
USP (U. S. Pharmacopoeia) is the US certification required by Pharmaceutical companies to meet federal standards. This assures the buyer to be getting a very fine, black, odorless, and tasteless powder, free from gritty matter, with less than 4% ash residue, and acid-washed to remove virtually all of the remaining inorganic constituents. This also allows the activated charcoal to be labeled and sold as “Food Grade”.
