What it is
Magnesium silicate is a mineral compound made of magnesium, silicon, and oxygen. It is found naturally in minerals like talc and enstatite. It is often produced industrially by reacting magnesium salts with silicates.
Why it's used
Magnesium silicate is used as an anti-caking agent to prevent powdered food ingredients from clumping together. It helps maintain a free-flowing texture in products like powdered sugar, salt, and spice blends. It is commonly found in candy, baked goods, and powdered drink mixes.
Health notes
Magnesium silicate is generally recognized as safe (GRAS) by the FDA for use as an anti-caking agent. It is poorly absorbed by the body, meaning it passes through the digestive system largely undigested. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated magnesium silicate and established specifications for its use.
Allergen info
Magnesium silicate is not derived from any of the 9 FDA major allergens. It does not contain gluten.
