Additional Information

D-Aspartic Acid is one of the enantiomers of the amino acid known as Aspartate, where the common dietary enantiomer is L-Aspartate. L-Aspartate is a non-essential amino acid and can be incorporated into protein structures, although D-Aspartate is not commonly associated with protein structures. D-Aspartate has been found to be a constituent of human cartilage, enamel, and can be accumulated in the brain as well as being a constituent of red blood cell membranes.

D-Aspartic Acid (DAA) is suggested to be a regulator of testosterone synthesis and may act on a stimulatory receptor (NMDA). D-Aspartic Acid shows promise in increasing nitric oxide levels.
