D Aspartic Acid (D-aspartate, DAA) is a non-essential amino acid with an acidic side chain. Excluding glycine, every amino
acid used in synthesizing proteins has a “D” and “L” form. L forms and D forms of the same amino acids are identical in every
way except for the manner in which they bend light rays.
The L form of aspartic acid is believed to be a vital constituent for DNA synthesis. The D form is used by the mid-brain to induce
the release of luteinizing hormone (abbreviated LH), human growth hormone (hGH) and follicle stimulating hormone (FSH).
