Product Overview

Magnesium carbonate is an inorganic salt with the chemical formula MgCO3. It occurs naturally as several minerals, the most common being magnesite and dolomite. For commercial and industrial use, it is often produced synthetically.

It appears as a white, lightweight, porous powder that is odorless and insoluble in water. It has several hydrated forms, including the pentahydrate and the basic hydrated form commonly sold as a supplement.

Primary Applications

Dietary Supplements & Antacids: Used as a source of elemental magnesium and an effective ingredient in over-the-counter antacids to relieve heartburn and indigestion.
Sports & Fitness: Widely known as "Sports Chalk," it is used by gymnasts, weightlifters, and rock climbers to absorb sweat and improve grip.
Food Industry: Acts as an anti-caking agent (E504) in table salt and spices, and serves as a drying or color retention agent.
