What is Magnesium Stearate?

Magnesium stearate is a white, powdery substance that acts as a flow agent in the production of pharmaceuticals and supplements, helping to prevent ingredients from sticking to equipment. It is the magnesium salt of stearic acid, a fatty acid that can be sourced from both plant and animal fats. While it is widely used in tablet formulations, the origin of the stearic acid can be a concern for those following a vegan diet unless it is specified as vegetable-based.

Why People Avoid Magnesium Stearate

People, especially those following vegan diets, may avoid magnesium stearate due to its potential derivation from animal fats.
