Hard Rhino D-Aspartic Acid (unflavored) is a pure form powder with no excipients or fillers, available in multiple sizes.
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 (N-methyl-D-aspartate). D-Aspartic Acid shows promise in increasing nitric oxide levels. Continuous supplementation of D-Aspartic Acid may only provide temporary increases in test levels for healthy men. Cycling of D-Aspartic Acid is recommended and the most effective means of use.†
