Does D-Aspartic Acid Boost Testosterone?

D aspartic acid and testosterone levelsMany men face low testosterone levels, usually after the age of 30. The reduced level of the male hormone leads to a variety of issues including lower sex drive and lower sperm count. There are products on the market that purport to increase testosterone levels, but not all have scientific evidence behind them. D-aspartic acid is one supplement that shows promise in elevating natural testosterone levels in men.

What is D-Aspartic Acid?

Aspartic acid is an amino acid produced by the body. It is one of the 20 amino acids that are the building blocks of the various proteins used to create tissues throughout the body. There are a few forms of aspartic acid in the body. The l-form of the amino acids all builds tissue. The d-form of amino acids is a signaling molecule. In certain tissues of the body that produce hormones such as the pituitary gland, the hypothalamus, and the testes, the amino acid l-aspartic acid is converted and becomesĀ  d-aspartic acid.

How Does D-Aspartic Acid Increase testosterone levels?

As a signaling molecule, d aspartic acid triggers the release of the gonadotropin-releasing hormone (also known as GnRH) and informs the pituitary gland that testosterone levels in the blood are decreasing. The GnRH also monitors the testosterone levels created from the testes, the luteinizing hormone (LH) and the growth hormone (GH) of the endocrine system that includes the pituitary gland and the hypothalamus. All of these hormones and tissues work together to create and release testosterone. D-aspartic acid increases the production of testosterone and its release by first signaling the body to release the gonadotropin and luteinizing hormones. Both the testes and the pituitary gland can trap the d aspartic acid that is circulating in the body and this helps to increase testosterone levels as well.

Scientific Studies That Prove That D-Aspartic Acid Increases Testosterone Levels

A research study reported in the Journal Reproductive Biology and Endocrinology shows that d aspartic acid supplements do increase testosterone levels in both humans and rats. Although the sampling of human volunteers was small — only 23 men between 27 and 37w ere in the study- the findings show that in 12 days testosterone levels increase by 42 percent. The most important thing is the dose. Taking 3 grams a day is sufficient. Another study shows that taking 6 grams of d aspartic acid a day actually decreases testosterone levels.

My Experience Using D-Aspartic Acid

I do use a product that contains DAA myself, I dose at 2.6mg per day. I use a product called Prime Male which includes DAA alongside other effective natural ingredients such as Magnesium, Zinc and Vitamin D. I generally do advise stacking d aspartic acid with other test boosters, especially Vitamin D, and Magnesium as you will see much more impact from this.


D-aspartic definitely is effective in boosting testosterone levels. However, you must take a daily dose of not more than 3 grams to reap the benefits of this amino acid.
