Asparagine is an endogenous amino acid, synthesized directly in the human body, and also in foods containing high amounts of plant and animal protein. It is also available as nutrients, supplements and mineral preparations (e.g. Magnesium or zinc aspartate [ZMA]). It participates directly or with support of synthetics in physiological processes: energy conversion, synthesis of purines and urea. Its derivative (asparagine) with phenylalanine (exogenous amino acid) is a part of aspartame [E-951]. There is more and more positive feedback from athletes about the usefulness of its equivalent d-aspartic acid to increase the of testosterone potential.
