It's important to know exactly what is in a dietary supplement capsule before you pop it in your mouth. When magnesium and stearic acid are bound together, the compound is known as magnesium stearate, an anti-caking agent that helps keep the ingredients in tablets and capsules from sticking to processing equipment. This results in consistent amounts of active ingredients in each tablet or capsule.
