You will never find magnesium stearate in our products. Magnesium stearate is a white water-insoluble powder made of magnesium and the saturated fat, stearic acid. It is a common additive in processed foods, drugs, and dietary supplements. Magnesium stearate powder is very fine and slippery. Consequently, it serves as a good lubricant or “flow agent” in the manufacturing of dietary supplements and pharmaceuticals by helping the active ingredients “flow” through the machinery more easily during production. Although magnesium is part of the compound, magnesium stearate itself has minimal nutritional value.
