D-aspartic acid - a protein amino acid important for men

What is DAA, or D-aspartic acid? According to publicly available scientific knowledge (Roshanzamir et al., 2017) in the human body, D-aspartic acid has been detected in both fetal and adult brains, as well as in the cerebrospinal fluid of adults. The localization of this amino acid in the nervous system suggests that it plays a role in neurotransmission and neurosecretory functions. D-aspartic acid is also found in endocrine systems, particularly those related to the reproductive system, such as the adrenal glands, pineal gland, pituitary gland, and testes. DAA plays an important role in the biosynthesis and/or secretion of hormones in the endocrine glands, including the regulation of testosterone production. As reported by the authors of the 2017 publication, D-aspartic acid contributes to the production of more testosterone in the testes, and based on the available research, it was found that DAA regulates the release and synthesis of testosterone through many ways of the hypothalamic-pituitary-gonadal axis.

DAA and muscle mass and strength

Due to its role in the regulation of testosterone levels, D-aspartic acid has become a popular ingredient in dietary supplements intended for people who want to build muscle mass and strength. Melville et al., in a 2015 paper appearing in the Journal of the International Society of Sports Nutrition, suggested a link between basal total testosterone levels and training benefits. A decrease in overall testosterone levels may reduce the likelihood of interaction with androgen receptors in muscles and nerves, which would reduce the rate of testosterone-initiated muscle protein synthesis, which over time may translate into reduced training gains.

Forms of aspartic acid - remember the differences

Aspartic acid occurs in two forms, as L-aspartic acid and D-aspartic acid, which perform various functions in the human body. L-aspartic acid becomes part of proteins synthesized in the body, e.g. is involved in the synthesis of four essential amino acids in humans: methionine, threonine, isoleucine and lysine. D-aspartic acid is not used for protein synthesis. It is normally found in the pituitary gland and testes and is involved in the regulation, release and synthesis of testosterone and luteinizing hormone.

DAA in capsules

If you want to supplement your daily supplementation with DAA, reach for D-aspartic acid in a convenient form of capsules. Our proposal is 1500 mg of DAA in a daily portion.
