What is Magnesium Carbonate?

Magnesium carbonate is a white, powdery mineral compound that occurs naturally in the environment and is often synthetically produced for industrial and consumer uses. It is typically made by a process called precipitation, where magnesium salts are combined with carbon sources.

This compound is used as an antacid to relieve heartburn and indigestion, in athletic products for better grip, and as a drying agent in various foods and pharmaceuticals. The health evidence indicates that magnesium carbonate is generally considered safe when used in typical amounts found in food and cosmetics.

When you see magnesium carbonate on a label, it’s usually there to stabilize a product or improve texture. It's not known for having any significant health risks except for mild digestive upset if consumed in large amounts.

Commonly found in: antacids, chalk for sports, supplements, pharmaceuticals, cosmetics
