Magnesium Stearate
What is Magnesium Stearate?
Magnesium Stearate is a fine white powder made from magnesium and stearic acid, which is a saturated fatty acid. It's commonly used in the pharmaceutical and supplement industries as a flow agent, preventing ingredients from sticking to manufacturing equipment.
In products, it's primarily used to ensure consistent texture and distribution of ingredients. There is some debate over its health effects, but current research generally finds it safe at typical consumption levels. Some concerns arise with high exposure, but these scenarios are uncommon in daily product use.
When you see Magnesium Stearate on a label, it's often in very small amounts. Its presence is mainly about the ease of manufacturing and quality consistency, rather than a primary functional ingredient in the consumer product.
Commonly found in: Supplements, Medications, Candy, Makeup, Synbiotics
Magnesium Stearate is considered Generally Recognized As Safe (GRAS) by the FDA.
Most studies find Magnesium Stearate safe, although very high doses could pose minor risks, which are unlikely in normal use.
While the stearic acid can be derived from animal or plant sources, vegan-friendly certifications depend on sourcing.
