D-ASPARTIC ACID: The Backbone Of Bodybuilding Supplements

d-aspartic acid

D-aspartic acid hope you is a potent amino acid regulator that assist in testosterone synthesis.

It also acts as a stimulatory neurotransmitter that aids male fertility.

Males that supplement D-aspartic acid generally experience temporary increases in testosterone levels.

D-aspartic acid is one half of the amino acid aspartic acid, the second half is known as L-aspartate.

D-aspartic acid is a proven testosterone booster, ideally suited to infertile men, as well as athletes, who will use it as a “testosterone booster”.

Increased testosterone levels tend to last for a round a week and a half in healthy men, after which testosterone levels return to their normal point.

D-aspartic acid primarily works in the central area of the brain, inducing it to release hormones such as the luteinizing hormone, the growth hormone, and the follicle stimulating hormone.

In some cases, D-aspartic acid has demonstrated its ability to build up the testicles while it helps to alleviate a “rate limiting step” of testosterone synthesis, which subsequently leads to a minor testosterone increase by itself.

A lot more research is needed into D-aspartic acid, because existing studies have attempted to assess its role within the body under normal conditions, and not in the framework of a supplementation study.

The Best Way To Take D-Aspartic Acid

The recommended dosage for D-aspartic acid is 2,000-3,000mg, and it should be taken daily.

Four studies have used various supplementation protocols, for example, one study used 3000 mg over the course of 12 days, followed by one week where it was not used.

Another study did not so much cycle D-aspartic acid supplementation, but instead used 2,000 mg of D-aspartic acid continuously and no harm was caused.

To be sure, further study is needed to determine whether D-aspartic acid should be used as part of a cycle.

Scientific Studies

We have obtained a summarized version of different clinical studies that were carried out on D-aspartic acid. Here are the findings…

Testosterone Enhancement: According to three studies, there appeared to be dramatic increases in testosterone in the majority of subjects to the tune of 30-60%.

Lean Muscle Increase:  As a result of one study, no significant changes occurred in the muscle mass in healthy trained men.

Fat Loss: As a result of one study, fat mass did not appear to be altered with D-aspartic acid supplementation coupled with exercise.

Power Enhancement: As a result of one study, healthy trained men did not experience any increases in power output when supplemented with D-aspartic acid, coupled with the resistance training.

Weight: As a result of one study, there were no significant changes in body weight when healthy males were supplemented with D-aspartic acid, coupled with resistance training.

Fertility:  As a result from two studies, limited evidence exists that D-aspartic acid can be the cause of increased activity in men, where one study noted that a group increased from no conceptions to 26.6% who were subsequently able to conceive.

Sperm Quality: As a result of one study, it appeared that D-aspartic acid was shown to be effective in increasing sperm quality.  

Sperm Count: As a result of one study, notable improvements in sperm count in infertile men varied between 50-100%.

Seminal Motility:  As a result of one study, seminal motility ceased between 50-100% in infertile men.

Luteinizing Hormone: As a result of one study, increases in LH concentrations were noted to be between 30-60% in infertile men. This directly correlated with the testosterone increases observed in this study.

Conclusion

tribulus terrestris

As you can probably see for from these clinical results, D-aspartic acid is an extremely effective testosterone booster in itself, although the effects may be only temporary.

An important thing to note is, despite the temporary nature of the testosterone boost, the long-term benefits such as increased muscle mass, increased bone density as well as a much improved sexual and fertility function will still be enjoyed long after any cessation of D-aspartic acid supplementation.

Finally, although no increases in muscle mass or strength gains were reported, testosterone by its very nature works to increase these two elements over time.
