Primaforce D-Aspartic Acid 100g

D-Aspartic Acid (DAA) is the newest natural testosterone booster on the market. DAA is the D-form of the amino acid aspartic acid. The body can produce DAA from the nonessential amino acid L-aspartic acid (the dietary form of aspartic acid). D-form amino acids, such as DAA, are found in higher concentrations in specific tissues in the body. For example, higher concentrations of DAA are found in the testes, pituitary gland, and hypothalamus all of which are areas involved in hormone production.

One big difference between DAA and other natural testosterone boosters is there is actually scientific data in humans showing it to effectively increase testosterone levels. A study by Topo et al. showed that supplementing with 3 grams of DAA increased circulating luteinizing hormone (LH) levels by 33% and testosterone levels by 42% in men aged 27-37 years old.* Further studies need to be done to examine DAA’s affects on estrogen and prolactin levels, but at this time there are no side effects reported with DAA use. DAA is a natural amino acid found in our food supply and produced by the body making it a great tool to naturally increase healthy males’ testosterone production.
