What is D-Aspartic Acid (DAA)?

D-Aspartic Acid (DAA) is a non-essential amino acid involved in hormone-related signaling. It is commonly used as a supplement for testosterone and male fertility support.

Does D-Aspartic Acid increase testosterone?

DAA may raise testosterone temporarily in some men, especially those with lower baseline levels. Results are mixed, and effects are often small or not seen in trained athletes.

Can D-Aspartic Acid help male fertility?

Some research suggests DAA may improve sperm parameters such as count and motility in subfertile men. It is not a substitute for medical evaluation of infertility.

What is a typical D-Aspartic Acid dosage?

Common supplemental doses are 2,000–3,000 mg per day. Follow product directions and consider cycling or limiting duration if advised by a clinician.

Who should avoid D-Aspartic Acid?

People who are pregnant or breastfeeding, under 18, or have hormone-sensitive conditions should avoid DAA unless a clinician advises otherwise. If you use hormone-related medications or have endocrine disorders, consult a healthcare professional first.
