2021's 10 Best D-Aspartic Acid
TOP SUPPLEMENTS

Best D-Aspartic Acid

Aspartic acid or aspartate is a non-essential amino acid which is produced naturally by the body in the testes, hypothalamus, and pituitary gland. It can also be acquired from foods rich in protein such as poultry, beef, and dairy products. As with all amino acids, minus glycine, it exists in two forms called L-aspartic acid and D-aspartic acid. The latter is found in the nervous and endocrine systems.

D-Aspartic acid is primarily marketed as a training enhancement supplement that can boost male testosterone levels. Let’s take a look at some of these potential benefits.

DAA Health Benefits

Testosterone

The process by which D-aspartic acid supposedly increases testosterone is by boosting your luteinizing hormone. Produced in the anterior of the pituitary gland, the luteinizing hormone controls the male and female reproductive system and their subsequent hormones, testosterone and progestogen. (See Reference 2)

A 2009 study found D-aspartic acid to increase testosterone in men with low testosterone by up to 15% after 6 days and 42% after 12 days of consecutive use. Levels fell to 22% three days after supplementation was stopped. In contrast, a study from 2017 found 6 grams of daily D-aspartate supplementation for 12 weeks to have zero effect on testosterone levels. They also monitored muscle gain between the control and trial groups, and they found no significant difference. All participants had a minimum of 2 years of resistance training experience. (See Reference 8)

Findings seem to be mixed on whether or not D-aspartic acid has a significant testosterone boosting effect, although the evidence does point towards a greater likelihood of effect for beginner lifters with 0 – 2 years of training and people with lower than average initial levels of testosterone. (See Reference 1)

Male Fertility

Naturally-occurring D-aspartic acid has been linked with the development of healthy sperm in humans. (See Reference 3) Furthermore, a study on infertile men found significantly lower D-aspartic acid levels in their sperm and semen when compared to fertile men. (See Reference 4)

So how does D-aspartic acid supplementation affect male sperm quality? (See Reference 5) Well, a 2012 study performed found a daily dose of 2.66 grams of D-aspartic acid to increase sperm count and their swimming ability over a 90-day period in 60 men with a low number and quality of sperm. As a result, 26 of the male’s female partners became pregnant. Research into the male fertility boosting properties of D-aspartate is promising and ongoing. (See Reference 9)

Female Reproduction

There is preliminary research that D-aspartate may also play a positive role in female reproduction. (See Reference 6) Results found a direct link between a decline in D-aspartic acid levels and decreased pregnancy success/egg quality. However, there is no scientific evidence of D-aspartate supplementation, improving these factors, and subsequently female fertility.

Cognitive

A 2010 study examined the effect of 4 milligrams of daily sodium D-aspartate for 12 to 16 days in a rats capability of finding a hidden platform in a water maze system. (See Reference 7) The treated group displayed significantly quicker results in finding the hidden platform and had 2.7 times the amount of D-aspartic acid in their hippocampus. These findings provide evidence that D-aspartic acid can strengthen cognitive functions such as the processes of memory and learning, although a similar study on humans has yet to be performed. (See Reference 1)
