As men age, testosterone production falls — this is the unfortunate truth about this powerful hormone that is responsible for muscle growth, fat loss, and many other positive attributes. During puberty and into the 20s, testosterone production ratchets up sharply, and then it drops off slowly forever, naturally.
There is hope, however, in the form of D-Aspartic Acid (DAA). It is an amino acid that, research shows, can increase natural testosterone production by up to 40 percent in men mainly by increasing levels of luteinizing hormone (LH) from the pituitary gland. The result is a mimicking of the same body state experienced by men in their 20s — a natural elevation of testosterone based on the same processes the pituitary goes through. In 2007, an Italian study addressed DAA and its role in the male body, showing the pro-testosterone hormones the body will create with DAA supplementation:
In the pituitary gland, it stimulates the secretion of the following hormones: prolactin (PRL), luteinizing hormone (LH), and growth hormone (GH) In the testes, it is present in Leydig cells and is involved in testosterone and progesterone release.
Among the benefits of increased natural testosterone are enhanced libido, elevated mood, and, of course, strength, muscle growth and fat loss. Supporters of DAA research note the results of a particular study featuring a test group that ingested it:
…Researchers gave a couple of dozen men aged between 27 and 37 a daily dose of 3.12 grams of for twelve days consecutively. Twenty other men were given a placebo. The testosterone level in the subjects that received the supplement had risen by 33% after the twelve days.
Now, there are a few DAA-based products in the supplement world, but be warned — there are side effects in many of them. The body’s No. 1 goal, in any process, is to achieve balance, and this goes for hormonal levels too. This means that for every huge spike in testosterone, there is a reaction by the body that is undesirable: Aromatization, the conversion of androgens (in this case, testosterone) into estrogens. Obviously, this is not what you want if you’re trying to add muscle and lose fat!
FORZAONE’S 1-XD is a powerful DAA product that also addresses the issue of aromatase by including an anti-estrogen blend to combat any estrogen conversion. DAA alone will be subject to aromatization, meaning that to get the full effect of it in a supplement, you would have to also find an estrogen inhibitor to counteract your body’s natural inclination to balance off your new, elevated testosterone levels. However, this inhibitor is already included in 1-XD, making it a clear choice for men who want to improve muscle size and strength while regaining their youthfulness.
