D-Aspartic Acid is one of the most common ingredients of a testosterone booster supplement, we have seen this in our many reviews that it is almost present in our 80% of boosters that we reviewed.

And it is important to be in testosterone boosters because D-Aspartic Acid has so health benefits and that is the reason for making this post of D-Aspartic Acid Benefits.

D-Aspartic Acid Benefits

We mention the benefits of each ingredient present in any supplement but today we are discussing D-Aspartic Acid Benefits in brief and in explain as well.

Many of our readers are still confused about the testosterone boosting foods and supplements.

We already made a post for all of our readers regarding Best testosterone foods.

Testosterone Boosting Foods List: Best foods to increase test levels.

We are covering everything related to the D-Aspartic Acid Benefits in our this post.

So, sit back and have your protein shake or coffee ready because this post is going to be quite lengthy.

What is D Aspartic Acid

D-Aspartic Acid Benefits

D Aspartic Acid is a form of Aspartic Acid and the short form of its name is DAA, this is an amino acid.

I think you all know that amino acids are important for any healthy and fit human being and D Aspartic Acid is one of them as well.

Amino acids can be produced by human beings and animals as well inside their body naturally.

But there are some amino acids that humans cannot produce inside their bodies and those types of amino acids are called essential amino acids.

And the amino acids that human can produce inside their bodies are called non-essential amino acids.

But humans can produce D Aspartic Acid inside their bodies naturally and that is the reason it comes under nonessential amino acids.

A human body can produce D Aspartic Acid in two forms D-Asp or D-Aspartic Acid and L-Asp or L-Aspartic Acid.

These two have the same chemical formula but the structure of their molecules are mirror images of one another.

L-Aspartic Acid can help the human body in the making of proteins.

But we are discussing about D-Aspartic Acid, this amino acid cannot help in the making of protein instead it helps the body in releasing other hormones. (1, 2)

D-Aspartic Acid Benefits

There are so many D-Aspartic Acid Benefits, D Aspartic Acid helps in releasing a hormone inside your brain which then helps in increasing the production of the testosterone(3).

And that is the one of the biggest reason for having D Aspartic Acid in their testosterone boosters.

But it has so many other benefits other than just increasing the testosterone production.

  • Boosts testosterone levels

D-Aspartic Acid BenefitsIn our first study, researchers give twenty men, a daily dose of D-aspartate (DADAVIT) for continuous 12 days and they didn’t give anything to the other 20 men nothing to compare the data.

And they also perform the same kind of test with rats, they give 10 rats a solution of  20 mM D-aspartate and didn’t give anything to the other 10 rats to compare the end results.

They have done this test with rats for straight twelve days.

And when this test finishes they found that both men and rats have an increase in the production of testosterone and Luteinizing Hormone. (4)

And in the second study, now this time researchers do this research with 10 obese men who are facing low testosterone levels in their body.

They provide them to take DAA or Vitamin D3/nitrate supplements two servings a day for straight twenty-eight days.

And after 28 days of research, 10% of men found no change in their testosterone levels but some other men found an increase in their test levels by 20%. (5)

  • Improve Sperm Quality

DAA or D-Asp can help in releasing many hormones, and it also helps in the development and production of sperms as well. In one study conducted with rabbits, researchers give rabbits a mixture of L-Asp and D-Asp, for straight two weeks and after the two weeks, they found an increase in their sperm count and mobility of sperms. (10)

And in another study, researchers told some men to take 2.6 grams of D-Asp for 90 days and after the gap of 90 days, they found that 60 men have increase sperm count and the mobility of sperms and these all 60 men are having a problem of low sperm count previously. (13)

  • Improve female fertility 

In a study conducted with 20 women which has an age of 22 to 40 years old and they all are facing the problem of reduced D-Asp hormone because of aging, and after the research, researchers found that the decline in the D-Asp hormone is linked with the decrease in their egg quality and reduction in successful pregnancies. (11)

  • Improves Brain memory

In one study conducted with rats, free D-Asp helps the cell communication and memory inside brains. And in another study conducted with men, they found that an enzyme DAO can help or alter the production of D-Asp hormone which then boosts the memory and thought process. (12)

There are some people who are searching for D Aspartic Acid Sperm, I think they are searching for that DAA can help in sperm mobility or something like that.

So, here is the answer DAA can help you in improving the sperm quality. We provided the links for all the D-Aspartic Acid Benefits as well, you can read them.

Researches

In many studies, it is found that D Aspartic Acid can help in increasing the testosterone production but in many studies, it is found that it doesn’t help in increasing the test production.

In our first study, researchers give twenty men, a daily dose of D-aspartate (DADAVIT) for continuous 12 days and they didn’t give anything to the other 20 men nothing to compare the data.

And they also perform the same kind of test with rats, they give 10 rats a solution of  20 mM D-aspartate and didn’t give anything to the other 10 rats to compare the end results.

They have done this test with rats for straight twelve days.

And when this test finishes they found that both men and rats have an increase in the production of testosterone and Luteinizing Hormone. (4)

And in the second study, now this time researchers do this research with 10 obese men who are facing low testosterone levels in their body.

They provide them to take DAA or Vitamin D3/nitrate supplements two servings a day for straight twenty-eight days.

And after 28 days of research, 10% of men found no change in their testosterone levels but some other men found an increase in their test levels by 20%. (5)

And in the third study, researchers told 30 men to take D-aspartate for 90 days and after the 90-day interval, they found that an increase in their testosterone levels by 30–60%.(6)

These are the studies which prove that D Aspartic can help in testosterone production and Luteinizing Hormone.

But there are some other studies which prove that this is not true, that D-Aspartic Acid cannot help in test production.

In one study that there is no increase in their testosterone production, in young adult people who do weight training and take D-Aspartic Acid for straight 28 days. (7)

And in one another study 24 men, they took high doses of D-Aspartic Acid, around 6 grams per day for straight two weeks and they are doing weight training as well, and they found a decrease in their test levels. (8)

But what are the other D-Aspartic Acid Benefits? Here are some of the short list of D-Aspartic Acid Benefits.

D Aspartic Acid Bodybuilding

D-Aspartic Acid Benefits

In bodybuilding D Aspartic Acid helps a lot, but as you saw in above studies that D Aspartic Acid only help those people who have low testosterone levels and doesn’t work with people who do weight training.

But there are some people who are searching for D Aspartic Acid Bodybuilding, and we are here for removing all the confusions for our readers and other fitness geeks.

DAA basically works inside the central brain and help in releasing hormones like a follicle-stimulating hormone, growth hormone, and luteinizing hormone.

In some studies, it is also proven that DAA can help the body in increasing the muscle and strength of the person because of the increase in testosterone levels.

In one study researchers found that taking DAA and doing weight training together for twenty-eight days can help in increasing the muscle mass and strength.

And the increase in 1.3-kg or 2.9-pound in lean mass and this happened with the placebo group as well, they also found an increase in muscle mass of 1.4 kg or 3 pounds.

Both the groups do the same training and take similar kind of diet as well. (7)

And this happened with another study and this study is conducted for three months and they found similar kind of results as well.

Two men do the same exercise and took the same kind of diet but one take DAA additional and they have gain same kind of muscle mass. (9)

These two studies proved that as well that taking DAA with training cannot help you that much, whether you take or not it doesn’t influence.

The only thing is that there is no studies or researchers done with some other kind of training.

  • Headaches
  • Irritation
  • Nervousness
  • Loss in Testosterone Production (8)

This is proven with studies as well.

In the first study (6) conducted by researchers and they told 30 men to take D-aspartate for 90 days, and after the interval of 90 days, researchers perform a blood test to know the changes occurred in their body.

But they found nothing adverse happened in their bodies.

But in another study, researchers told 10 men to take DAA for 28 days and after 28 days one man from the placebo group told that it found some issues with taking DAA, and the issues are like as Headaches, Irritation, and Nervousness.  

D-Aspartic Acid Benefits

In one of the study that we mention (8), taking DAA with weight training decreases the testosterone levels of the subjects.

But there is no proven study that mentions the D-Aspartic Acid Side Effects, so we can say that you will face no side effects of taking DAA if you take the recommended dosage of the supplement.

Because anything that you take above its recommended dosage harm you and your body as well.
