There has been much controversy about magnesium stearate and its supposed ill effects on health and bioavailability. The scientific research, however, does not support the argument that it is harmful. A small amount of magnesium stearate is included in some of our capsules as a lubricant that facilitates the flow of powdered herbal extract and makes it possible to properly fill the capsule. Magnesium stearate is the magnesium salt of stearic acid, which is a saturated fatty acid that occurs abundantly in vegetable and animal oils and fats. To give you an idea of scale here, 1 tbsp of olive oil has 266 mg of stearic acid, 1 tbsp of coconut oil has 381 mg of stearic acid, and a hamburger patty has 1599 mg of stearic acid. Meanwhile, one of our capsules typically has 1-10 mg of magnesium stearate, the latter consisting of 96% stearic acid. In fact, we are phasing out magnesium stearate as a lubricant in our capsule manufacturing process. Stay tuned for magnesium stearate free caps—coming soon!
