D-Aspartic Acid (DAA)

Product Name:D-Aspartic Acid (DAA) Synonyms:DAA;H-D-Asp-OH; (R)-2-Aminosuccinic acid;D-Asparate; CAS NO: 1783-96-6 Application: Pharmaceutical intermediate; raw material of peptide synthesis 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 is formed when the enzyme aspartate racemase converts L-aspartic acid into D-aspartic acid in the testes and other glands within the body. D-aspartic acid plays a vital role in the manufacturing of sperm cells and sex hormone production. Human studies have shown a significant increase in luteinizing hormone (LH), a messenger hormone that signals the testes to produce more testosterone, and a correlation to boosting testosterone levels in men when supplementing D-aspartic acid. Consuming D-aspartic acid supplement will increase the testosterone level for those who normally want it and most probably sterile men will certainly gain from this. The Luteinizing Hormone or the LH aids produce testosterone in the Leydig cells. Sperm cells are therefore created. Diseases will follow if there is low LH level in the body. Intake of the supplement will help induce more LH and the testosterone will be produced. No side effects have been reported yet if one will take Daspartic acid supplement day-to-day. Daa pure is one of the reliable supplements in the market. Taking Daa pure supplement is a dependable enhancement compared to just getting it from your normal diet and can be absorbed much faster. Several D-aspartic acid testosterone supplements are circulating in the market now, mostly to answer the needs of impotence and other testosterone deficiency problem.
