D-Aspartic Acid (DAA) is an amino acid used in the biosynthesis of protein. Because DAA is commonly found in mammals, it is considered a nonessential amino acid. However, many men supplement DAA due to its positive effects on sexual health and athletic performance. D-Aspartic Acid has been linked to the process of producing Luteinizing Hormone (LH), which plays a role in synthesis of testosterone. DAA may also help boost energy, promote sexual health, help libido, and support the brain.** These statements have not been evaluated by the Food and Drug Administration.
