Is Magnesium Stearate Harmful?

(Is Magnesium Stearate Harmful?)

Does magnesium stearate cause arthritic pain or allergies?

Magnesium stearate is a common ingredient found in supplements and medication capsules. It is a flow agent, lubricant and binder that helps ensure the consistency and quality of your product.

It is derived from stearic acid, a saturated fat. The stearic acid is extracted from vegetable sources such as coconut oil and palm oil.

The National Center for Biotechnology Information recommends consuming less than 2,500 milligrams per kilogram of body weight (mg/kg) daily, which is the equivalent to 170,000 mg for a 150-pound adult. That amount should be safe for most people.

Does magnesium stearate affect the absorption of your pills?

It may delay tablet dissolution, but it does not impact the overall bioavailability of your supplement or medicine. The stearate is added to the tablets specifically so that they break down more slowly, not so that they are absorbed more quickly.

Does magnesium stearate have a laxative effect?

If you consume too much magnesium stearate, it can have a laxative effect. This can trigger a bowel movement or diarrhea, which can be uncomfortable and unpleasant.

Does magnesium stearate suppress your immune system?

It has been reported that small amounts of magnesium stearate can suppress your immune system, but this is based on laboratory studies where large amounts of stearic acid damaged cell membranes in immune cells. This type of study does not replicate how your body actually functions when you eat normal amounts of stearic acid, and it is unlikely that the small amount of magnesium stearate in your supplements would have such an effect.
