D-aspartic acid

D-Aspartic Acidis a naturally occurring amino acid found in the body.Aspartic acid was first discovered in 1827 by Plisson, synthesized by boiling asparagine (discovered in 1806) with a base.

D-aspartic acid is formed when the enzyme aspartate racemase converts L-aspartic acid into D-aspartic acid in the testes and other glands. This amino acid plays a key role in the manufacture of sperm cells and sex hormone.

Recent research involved giving men aged between 27 and 37 a daily dose of 3.12 grams D-aspartic acid for twelve days consecutively. Twenty other men were given a placebo. The testosterone level in the subjects that hadreceived the supplement had risen by 33 percent after the twelve days.

D-Aspartic acid is thought to rapidly increase the production of the testosterone via the pituitary gland and the testes by enhancing the cellular production of signal molecules that control the secretion of LH and testosterone.
