Magnesium stearate is a white, powdery substance that is composed of magnesium ions and stearic acid. It is a common ingredient in the manufacturing of various products, including pharmaceuticals, cosmetics, and food additives.
In pharmaceuticals, magnesium stearate is used as a lubricant to prevent ingredients from sticking to the machinery during the manufacturing process, and to improve the flow properties of powders. In cosmetics, it is used as a thickener, emulsifier, and skin protectant. In food additives, it is used as an anticaking agent, emulsifier, and release agent.
Magnesium stearate is generally considered safe for use in the amounts typically used in products. However, some people are concerned about the potential health effects of magnesium stearate, as it can potentially interfere with the absorption of certain nutrients. While the scientific evidence supporting these concerns is limited, it is still recommended to limit consumption of magnesium stearate as much as possible. In any case, it’s important to speak with a doctor or a healthcare professional before using products containing magnesium stearate, especially if you have any pre-existing health conditions.
