What is Magnesium Stearate?

Magnesium stearate is a compound made from magnesium and stearic acid, a fatty acid found naturally in animal and plant fats. It is typically produced by reacting sodium stearate with magnesium sulfate, resulting in a fine, white powder.

This ingredient is commonly used as a 'flow agent' in the manufacturing of capsules and tablets, helping to prevent ingredients from sticking to the machinery. Its role is crucial for ensuring the uniformity and quality of the final product. There is minimal evidence of negative health impacts when consumed in typical amounts, but some individuals may raise concerns about potential irritation or allergies.

When seen on a label, it usually indicates that the product is a supplement or medicinal tablet, where ease of manufacturing is prioritized.
