D-Aspartic Acid

DAA or D-Aspartic Acid is a new revolutionary compound based on an amino acid which can be found within the human body. It has received a lot of attention in body building circles, with claims that it can raise testosterone levels. Research has found this to be true but how much of the evidence comes from studies  done on humans?

First of all testosterone directly effects your protein synthesis levels. It is essential to ensure your natural testosterone levels are high so that your ability to repair damaged muscle fibers as well as add lean muscle mass to your frame is at it’s highest. Additionally, healthy testosterone levels enable your body to assimilate fat more easily as an energy source which in turn aids fat loss. High testosterone levels are very important for any serious male athlete, it allows for higher levels of strength and energy, meaning that you can add more muscle as well as burn more body fat. Essentially testosterone is an absolutely critical hormone for any male athlete..

In a recent article Charles Poliquin quoted research on humans that points to the fact after that 12 days dosing with D-Aspartic Acid, Testosterone was significantly higher and stayed higher for three days after stopping the supplementation. This was thought to be due to evidence that when supplementation is suspended, D-Asp levels are maintained for at least three days in the testes, continuing to trigger T production. He also points to a study conducted on rats at the same time, indicated that D-Asp regulates the synthesis of LH from the pituitary and T from the testes. This hormone response is mediated in the pituitary by cGMP and in the testis by cAMP.

Poliquin claims support further support  for D-Asp is seen with a recent study that gave a supplement of pycnogenol (60 mg/d), l-arginine (690 mg/d), and aspartic acid (552 mg/d) to Japanese patients with erectile dysfunction. Taking the supplement for eight weeks improved sexual function and increased testosterone slightly. The aspartic acid supplement was small, which may be one of the reasons there was only a small T increase.

In another particular study, researchers provided a group of males (aged 27-37) a daily dose of 3.12 grams of D Aspartic acid for twelve consecutive days. The growth compound level in the subjects that received the supplement had risen by 33% after the twelve days. The results of this study have massive implications for those looking to improve their athletic potential and also to improve their body shape with lean tissue.

In short this new supplement may have a very positive effect on your natural level of testosterone.

How to Take D-Aspartic Acid

Supplementation of D-Aspartic has been used in the range of 2,000-3,000mg daily. While the first study using 3,000mg used a cycling protocol (12 days on followed by a week without supplementation) the later study using 2,000mg daily noted that continual supplementation over 90 days was without harm. Evidence suggests splitting daily dose into 2 servings increases the benefits.
