Magnesium stearate is a white substance that has two equivalents of stearate and one magnesium cation. It is safe for human consumption. It is often used as a filling agent in the manufacture of supplement capsules. This substance has lubricating properties and prevents ingredients from sticking to manufacturing equipment during the compression of chemical powders into capsules or tablets. Most pharmaceutical formulations include a certain amount of lubricant to improve their flowability and prevent their adhesion to the surfaces of processing equipment.
