What is magnesium malate? More precisely, it is dimagnesium malate, because it consists of a molecule of malic acid bound to two magnesium molecules. These molecules are involved in many of the body's functions and are available in specific foods as well as in nutritional supplements. The combination of these molecules into magnesium malate is a patented form with a high bioavailability, i.e. it is easily absorbed during digestion and is well assimilated by the body. This product, which does not react with the stomach acids, does not disrupt the function of the digestive system, as other forms of magnesium are prone to do.
