It is a bioavailable soluble complex of calcium and aspartic acid with a mineral content of 13%. Calcium Aspartate is a bioavailability soluble complex of Calcium I-Aspartate acid. A food fortified with minerals, makes sense if the nutrient is metabilizable. It is not only calcium, but also particularly the anion fraction (Aspartate) of the ingested calcium source, which determines the bioavailability. The anion should be capable of physiological metabolism & be innocuous to the body. Both calcium I-Aspartate acids are naturally available in human body. These requirements are met by aspartate. Used extensively in calcium fortification of food, sports drinks & beverages. It is also used in pharmaceutical as calcium replenishes.
