d-aspartic acid details
d-aspartic acid (daa) is an amino acid that is naturally found in high quantities in the reproductive organs, hypothalamus and pituitary. through a same dependent, methyl-transferase reaction called nmda sythethetase, d-aspartic acid is converted into n-methyl-d-aspartate, which is a potent stimulator of the n-methyl-d-aspartate receptor pathway. d-aspartate is found in the hypothalamus, pituitary and testis in extremely high quantities during periods of heightened physical and sexual maturation.
d-aspartic acid function
d-aspartic acid is one of two forms of the amino acid aspartic acid. unlike its naturally occurring counterpart, no food offers pure d-aspartic acid, but rather a blend of both forms (d- and l-). d-aspartic acid is able to increase testosterone levels in healthy men according to a recent study, and seems to do so by both neurological and testicular methods which are synergistic. it also has other notable hormonal effects, as a metabolic by-product of d-aspartic acid is a regulator of growth hormone secretion and is intimately involved in melatonin secretion rates.
