Magnesium is fundamental for over 300 enzymatic processes in the body, not the least of which are related to generating energy. Aspartic acid is also a vital component for the generation of energy at the cellular level. Scientists have discovered that connecting magnesium with aspartic acid results in the formation of an effective magnesium additive, which in turn provides complementary energy for support of the body, not found in other additives. Swanson Magnesium Aspartate is a great substitute for all who want to cater to the health of their muscles and nervous system.
