Amino acids are the building blocks of protein and serve various functions in the body during childhood development and throughout adulthood. D-Aspartic Acid plays a role in metabolic support.* According to one study, D-AA supplementation may also support increased testosterone levels.*
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 D-AA has a role in the regulation of the release and synthesis of LH and testosterone in humans.*
