Magnesium chelate means to combine. When a mineral binds with certain molecules, it is easier to get absorbed into our body. Our digestive system quickly absorbs proteins or amino acids. It is the reason that most chelated supplements use amino acids as carriers for these minerals (such as magnesium). They improve a mineral’s bioavailability.
Bioavailability is the percentage of minerals that is absorbed in the intestines and transported to the bloodstream. The protein binders improve the minerals’ bioavailability by preventing the mineral from getting trapped by other components during digestion. Therefore, combining magnesium with an amino acid enhances the mineral’s absorption by our cells, resulting in its effectiveness.
