It's a synthetic product made from citric acid and magnesium hydroxide and filtrated and heated after chemical reaction; it has a good solution in the water and good flowing with finer particle size.
Magnesium citrate is used medicinally as a saline laxative and to completely empty the bowel prior to a major surgery or colonoscopy. It is available without a prescription, both as a generic and under various brand names. It is also used in the pill form as a magnesium dietary supplement. It contains 11.23% magnesium by weight. Compared to trimagnesium citrate, it is much more water-soluble, less alkaline, and contains less magnesium.
As a food additive, magnesium citrate is used to regulate acidity.
