D-Aspartic Acid (DAA) Increases Testosterone


D Aspartic Acid (DAA) Increases Testosterone   supplements    testosterone booster supplements d aspartic acid D-aspartic acid (DAA), an amino acid, has been shown to increase testosterone and luteinizing hormone (LH, a testosterone-controlling hormone) in men and rats. A study from the University of Naples in Italy found that testosterone increased by about 40 percent in men given approximately 3 grams of D-aspartic acid (DAA) for 12 days, compared to a placebo (fake D-aspartic acid). LH increased by 25 percent. In rats, the supplement increased testosterone by 51 percent and LH by 34 percent.

Many dietary supplements have been promoted to boost testosterone, but don’t have any human scientific studies to back them up. So that’s great news.

What’s so significant about this study is that DAA boosted testosterone in healthy young men (ages 26-37) at the peak of testosterone production, not elderly men or men suffering from low testosterone. DAA is the real deal, and has great potential as a safe and effective testosterone booster and dietary supplement. (Reproductive Biology and Endocrinology, 7: 120, 2009)
