The Magnesium Stearate issue


I suspect you are reading this article because you have been exposed to inaccurate circulating information which suggests that magnesium stearate is a harmful compound when used in supplements. In fact, some manufacturers appear to promote this myth as a marketing advantage to encourage sales of their products over those of their competitors.

The Facts about Magnesium Stearate

Magnesium stearate is a natural lipid (fat) component of animal foods and is also naturally present in human cells. In fact, we are eating it every day in a mixed diet. For every gram of fat naturally present in beef, there are about 15mg of stearic acid 1. A 100-gram serve of lean beef steak contains about 18 grams of total
fat2. This means that for this modest meal portion, one would consume around 270 mg of stearic acid.

One capsule of a product such as GliSODin contains 4mg of magnesium stearate. Realising how small this amount is compared to the amount one could consume in just one single food in an entire day puts the issue into a completely different perspective. So in an average day of a mixed diet including various other animal foods, one GliSODin capsule would contribute less than 1% of the total stearate consumed. In any event, since humans are physiologically animals, our own cells make stearic acid every day.
