What is D-Aspartic Acid?

D-aspartic acid is a nonessential amino acid that plays an important role in the neuroendocrine system and development of the nervous system.

While it is less bioavailable than L-aspartic acid, recent research indicates D-aspartic acid plays a role in regulating the release and synthesis of testosterone. It has become a popular dietary supplement among strength athletes like bodybuilders and weightlifters attempting to boost sports performance.

WARNING: This product is not to be used by men under 21 years old. Not to be used by women. Use of this supplement could trigger a failed drug test from various sports governing agencies.

Health Benefits of D-Aspartic Acid

In laboratory studies D-aspartic acid was shown to support luteinizing hormone (LH) production and subsequent testosterone release. LH is involved in the synthesis of testosterone.

In men, testosterone is a steroid hormone produced by the testes and adrenal glands. It supports lean muscle mass and helps generate energy.

Purity and Concentration of D-Aspartic Acid

This pharmaceutical grade amino acid contains no fillers, taste additives or anti-caking agents.

Suggested Use of D-Aspartic Acid

As a dietary supplement, take 2500 mg (rounded 1 tsp) to 3500 mg (scant 1/2 Tbsp) in one single serving, preferably with the first meal of the day, or as directed by physician. Do not take more than suggested serving or for longer than eight continuous weeks without at least four weeks off. Individual needs may vary.

For bodybuilders and performance athletes a 1/2 level teaspoon (approximately 1926 milligrams) two or three times per day (totaling about 4 grams to 6 grams per day) between meals is sufficient. You can see the full bulk density/volumetric conversion chart for D-Aspartic Acid here.
