Time for enlightenment, guys! Read on to know more about the amino acid, D-Aspartic Acid.

What Is D-Aspartic Acid (DAA)?

Amino acids are the building blocks of our body. They perform a number of important functions such and help in the formation of protein and hormones in the body.

Amongst the two forms of amino acids, the D-Aspartic Acid plays an important role in the lives of men who want to boost their testosterone. DAA is not used for protein formation, but for the secretion of hormones in the body.

DAA has the superb capacity of signaling the brain to release testosterone. Hence, this amino acid has becomes a popular ingredient in most of the testosterone boosting supplements in the world. Want to know the science behind it? Read further.

Relation With Testosterone

D-Aspartic Acid Testosterone

According to the research studies (the details can be checked below), DAA does not actually boost up your testosterone but it stimulates the organs to release the same in your body. Let us explain in detail.

DAA signals the pituitary gland present in your brain to send more LH. LH is transported to the Leydig cells contained in the testicles to release the collected form of testosterone in the body.

Thus, there is a temporary stimulation and release of testosterone in the body. The body benefits out of this free testosterone. Hence, a long-term solution of DAA supplementation will not be a proper advice. It should be consumed by men who want a sudden boost in their testosterone so that they can benefit in the short term itself.

Research Study

Plenty of studies have been conducted with regard to the testosterone levels but one can find mixed results.

Study [1] - In this study, healthy men in the age group of 27-37 consumed DAA supplements and found that majority of them had experienced increase in testosterone levels. When they stopped the supplement consumption, then their levels were still higher at 22 percent.

Study [2] - This study had obese men as subjects. They were given DAA for 28 days. This group experienced a mixed outcome but those with low testosterone definitely had higher levels than before the study.

Study [3] - In this study, DAA was consumed by the subjects for a longer duration, more than a month. There was a 30-60 percent shoot up in the testosterone.

Study [4] - This study was specifically targeted on the people who did weight training. But surprisingly, there was no significant increase in testosterone even though 6gms of DAA was administered to them on a daily basis.

Study [5] - In this long-term study of around 3 months, no testosterone increase was observed.

Thus, we can infer from the following studies that DAA causes an increase in testosterone only amongst inactive men or those who have low testosterone levels. This cannot be guaranteed for men who weight train in the gym. Similarly, the results can be observed only for a short term consumption of the supplements. In the long run, the effects of the DAA supplements cannot be seen.

Key Points

1. One of the two forms of the amino acids is the unique one, D-Aspartic Acid.

2. DAA has its own specific set of benefits and is different from those of other type of amino acid.

3. In case of infertile men, DAA can be definitely used as a testosterone booster. Athletes can use this same ingredient for a temporary period to shoot up their testosterone levels. This is because the increased testosterone levels will remain for at least 10 days in healthy men and after that, it will again drop down gradually. Hence, all the bodybuilders and athletes out there, go for a short-term and quick solution.

4. DAA informs the brain and stimulates it to release certain hormones known as luteinizing hormones, follicle-stimulating and growth hormone.

5. It also stimulates the testicles and assist in the testosterone synthesis by blocking out the unnecessary elements. This leads to a gradual increase in the testosterone levels.


D-Aspartic Acid can be consumed in its standard dosage of about 2000-3000 mg.

It can be consumed on a daily basis.

Whether you should take breaks in between, stack it with other supplements, or it should be cycled or not, all these things depend entirely upon the doctor’s opinion. Do not consume supplements without any analysis or prior consultation of the doctor. This doesn’t apply only to the DAA, but this instruction is with regard to any supplement available in the market and you have decided to add in your schedule.

Recommended dosage is also mentioned on the packet of the DAA supplements and one ought to comply with it. But if you want to add something to it, or take a break, or if you have any doubts, you can consult your doctor accordingly.

Side Effects

In order to determine the safety of D-Aspartic Acid, a team of researchers conducted a study in which 2.6 Gms of this ingredient was taken for a period of 90 days. It was inferred that no safety issues are found in this ingredient and that it can be consumed safely without any doubts in mind at least for a period of 90 days.

On the other hand, another study found that 2 subjects out of 10 subjects experienced symptoms such as headache and nervousness after consuming this ingredient. But the same side effects were experienced by the subjects of the placebo group. Hence, it can be said that it can case mild side effects such as headache for some persons but it is safe for the rest of us.

Other studies in which DAA was consumed by the subjects did not witness any form of side effects.

We need to research more to determine its safety to state it firmly. But the above studies are also sufficient enough to avail the advantages of this unique supplement.
