What is Magnesium Carbonate?

Magnesium is an essential nutrient found in many foods. Magnesium Carbonate (not to be confused with Magnesium Citrate) is an inorganic salt that is white in appearance with the chemical symbol MgCO3.

Magnesium Carbonate is insoluble and does not dissolve in water. Because of its insolubility, Magnesium Carbonate is often used in table salts to prevent clumping.

Also, often referred to as "chalk," Magnesium Carbonate is commonly used by athletes as a drying agent to aid with grip in sports like rock climbing, gymnastics, baseball, and weight lifting. 


Magnesium supplementation may help maintain overall health & wellness. Magnesium is used in more than 300 different reactions in the body and may help maintain healthy heart function. Magnesium Carbonate is an alkaline and may help in reducing stomach acid. It may aid in digestion, support oral & bone health, fortify the immune system, and aid healthy sleep. Magnesium Carbonate is also commonly used in skin products to help promote healthy skin.

    I recommend this product

    First time buyer with bulk supplement

    All went well with purchase and delivery


    Good quality, but not as easy to use as mag citrate

    The product is good quality. But I ordered magnesium carbonate in error, intending to order magnesium citrate, and the citrate is easier to drink and digest.

    Performance Enhancer

    I'm an aging athlete (70) and Magnesium is essential in conjunction with Calcium (2 parts Magnesium to one part Calcium). I still lift weights for 4hrs every other day and do lumberjack work on the days in between using non-powered hand tools (ax, saw, shovel, and rake) and pull the debris around manually in a hand-pulled cart. If it wasn't for Super Foods and supplements I couldn't do it.


    Calming and good for stimulating bowel movements!

    Great quality powder. It doesn’t have a taste which I really like. It helps me relax and get ready for bed. It’s also been helping me with constipation! It’s good for stimulating bowel movements without causing any discomfort. All around great supplement.
