D-Aspartic Acid (DAA)

D-Aspartic Acid (DAA) is a non-essential amino acid formed when the enzyme aspartate racemase converts an L-Aspartic Acid into DAA in the testes and glands. It is one of 20 proteinogenic amino acids, which are the building blocks of proteins.

One human study testing D-Aspartic Acid suggested that the amino acid boosted testosterone and luteinizing hormone release when taken over a 12-day period.* D-Aspartic Acid is found naturally in the testes, pituitary gland and hypothalamus, all of which are involved in hormone production.

The study found that DAA has a role in the regulation of the release and synthesis of LH and testosterone in humans.* Aspartic acid comes in two forms, L and D. The l-aminos build tissue. But when l-aspartic acid combines with enzymes in the testes, it becomes a d-aspartic acid, which supports testosterone levels in the blood and prompts production of more.*

The patients in the study took 3 grams of D-AA per day for 6 days, then for 12 days. Researchers surmised that testosterone levels increased in all individuals who the compound being researched.*
