What is D-Aspartic Acid (DAA)?

D-Aspartic acid is basically a type of amino acid that is formed naturally within the body, primary within the testes, as well as the hypothalamus and the pituitary gland. D-Aspartic acid is actually pretty rare, and although produced naturally within the body, the amounts produced are generally considered to be too small to be able to provide any real benefits. On top of helping to increase natural testosterone levels, D-Aspartic acid also plays a vital role in a person’s nervous system as well as their reproductive system in the process.

How does it work?

Located primarily in the testes and in the brain, this amino acid is responsible for triggering the release of a whole host of various hormones which play crucial roles in the human body. For example, anybody looking to increase their muscle mass can benefit from supplementing with this amino acid, due to the fact that it helps to regulate the production of growth hormone, as well as testosterone in the process. Because of this, you can then benefit from all of the positives associated with increasing your testosterone levels and growth hormone levels.

What are the main benefits of D-Aspartic Acid (DAA) supplements?

Just a few of the primary benefits associated with D-Aspartic acid include the following:

Increased muscle mass

Testosterone and growth hormone are both hormones that play vital roles in the growth and repair of muscle tissue, and generally speaking, the more of these hormones you have in your system, the more muscle you will be able to build. Due to the fact that this amino acid helps increase the synthesis of both of these hormones, as well as many others, many bodybuilders and people looking to increase their lean muscle mass, will actually include it in their supplement stacks.

Improved athletic performance

Another benefit associated with increased testosterone levels is the fact that it allows you to perform more efficiently from an athletic standpoint, therefore making it ideal for people involved in sports and rigorous physical activity.

Enhanced libido

Let’s face it, a healthy sex life can make for a happy relationship and if you’ve been finding your sex drive and your libido lagging lately, you may wish to think about supplementing with this amino acid. Not only that, but it could help improve your fertility as well, making it ideal for people looking to have children and start a family.

Other benefits include:

  • Enhanced libido
  • Increased strength levels
  • Regoluation of hormones
  • Increased levels of testosterone and growth hormone
  • Improved fertility
  • Increased muscle mass
  • Enhanced endurance
  • Improved mental focus
  • And more...

How and when should it be consumed?

Many experts recommend cycling this supplement, with people being recommended to take one week off after using the supplement for 14 consecutive days. The supplement should be consumed once per day, with a typical serving size being just 3g. Simply add 3g to your preferred liquid and enjoy. For optimal results, consume around one hour before training.

D-Aspartic Acid VS L-Aspartic Acid

D-Aspartic Acid and L-Aspartic Acid are both very similar and are often confused with each other, but despite this, there are still a number of differences between the two. L-Aspartic Acid for example, assists with protein synthesis and assists with the elimination of ammonia and waste products in the urea cycle. It also assists with the production of glucose energy, as opposed to D-Aspartic Acid, which plays a vital part in the production and regulation of key hormones.

What can it be stacked with?

D-Aspartic acid is actually often stacked with L-Aspartic acid, as combining the two together will provide you with all of the elements required for a significant increase in muscle mass, as well as athletic performance in the process. On top of that, it is also stacked with creatine monohydrate, BCAAs, L-Glutamine, whey protein, and casein protein, especially when individuals are looking to increase their muscle mass.
