Does D-Aspartic Acid Increase Testosterone?

D-Aspartic Acid as a Testosterone Booster – Will It Boost Your Testosterone?

The central role played by testosterone in both libido and bodybuilding is the reason for the rising popularity of testosterone boosters.

The adverse effects of synthetic boosters have led to the focus on the natural supplements that stimulate the increase in the production of the natural testosterone and its resultant benefits.

The active ingredient to most of these testosterone boosters like Testogen is D-Aspartic acid that is responsible for their efficiency and rising popularity.

But how exactly does D-Aspartic acid function?

D-Aspartic Acid

What is D-Aspartic Acid?

Before delving into how it works, there is a need to understand what D-Aspartic acid is. Aspartic acid is one of the 23 natural amino acids which function as building blocks for all the proteins besides neurotransmitters and hormones.

There are two forms of aspartic acid which are the more abundant L-Aspartic acid (LAA) and D-Aspartic acid (DAA).

They are the same in chemical composition and the only difference is that their molecular structure is a mirror image of each other and thus they are called isomers.

LAA is used in building proteins and is found in your body and in nature. D-Aspartic Acid, on the other hand, is used in the making and release of hormones which include testosterone.

How D-Aspartic Acid Works

Now that you understand what exactly it is, here is how it works. It acts by stimulating the brain to increase the secretion of testosterone from the testes.

It is made possible by stimulating the part called the hypothalamus that releases a hormone called Luteinizing Hormone Releasing Hormone (LHRH). This hormone stimulates the pituitary to release Luteinizing hormone (LH).

The luteinizing hormone acts on the testicles to release testosterone. Therefore an increase in D-Aspartic acid in the body through supplementation will sequentially result in an increase in the physiologic levels of testosterone.

How D-Aspartic Acid Works

Effect of DAA on Body Building

As an athlete, when you take in testosterone boosters like Testogen, what actually happens is that the D-Aspartic acid results in increased testosterone levels that:

* Speed up your recovery time after resistance training as muscle recovery is quicker
* Muscle growth is enhanced as there is up to 50% growth in lean muscle mass within a month of use.
* There is increased work capability as muscle strength is increased
* Increased metabolic rate where carbs and fats are burned faster producing more energy in the body(1).
* A more masculine appearance of the body as testosterone acts on all systems
Effects of DAA on Sexual Health.

It has now been well established that testosterone boosters will get your sex life back regardless of the age. Research has shown that the effects on your sexual health include the following;

* Increased sperm count and their motility that cures infertility in most men.
* More sexual appetite and libido in general.
* Better performance in bed due to more energy and the durability and power of erections.

How Long it Takes for Results to Show Up

Supplementation is not a magic pill where you pop one and the change is noticeable.

As it is a natural process of enhancement, the shortest time it may take for D-Aspartic acid testosterone boosters to show results according to scientific research is 10 days.

You may, however, need to use it for 3 to 4 weeks for best results and even better when it takes longer.

After the stoppage of supplementation, the levels will be retained at a higher level of about 20% for some time and so the results are long-lasting.

Safety and Side Effects

Research has been conducted to establish the safety and adverse effects of DAA. The findings show that it is safe to use DAA as it is naturally present even in the body.

Avoid taking too high doses as they will result in decreasing levels of testosterone as it functions through the negative feedback mechanism.

Some side effects may include headaches or irritability which are minor and have only occurred in a few users. If they occur, be sure to see your physician.


Testosterone is a golden hormone for men and supplementing it with boosters that contain D-Aspartic Acid has impressive benefits in bodybuilding and fertility.

Through acting naturally DAA is able to give results within 10 days without causing major adverse effects.
