D-Aspartic acid (D-Aspartic acid or DAA)
D-Aspartate and its analogues D-Sodium Aspartate and N-Methyl-D-Aspartate perform the tasks of neurotransmitters and neuromodulators. They also stimulate the production of signaling and enzyme proteins in nerve cells.
In the endocrine system, D-aspartate is associated with hormonal regulation. It increases levels of luteinizing hormone, gonadotropin, and follicle-stimulating hormone. Also a stimulator for the production of enzymes, in turn stimulating increments in the production of testosterone proper.
Proven benefits in humans:
Increases production of testosterone and lutenizing hormone.
Leads to a rise in aromatase synthesis due to increased testosterone, but direct stimulation via D-aspartate has also been suggested in separate in vitro studies.
