D-Aspartic Acid is an amino acid present in neuroendocrine tissues of humans, playing a role in the synthesis of both LH and testosterone. LH, of course, is secreted in a pulsatile fashion, thereby signaling the release of testosterone from the testes. D-aspartic acid is synthesized when aspartate racemase converts L-aspartic acid into D-aspartic acid. This conversion occurs in the testes as well as other tissues throughout the human body. Supplementation with 3 grams (3,000mgs) per day, orally, resulted in a 33% testosterone elevation in studies conducted.
Suggested Directions: Consume 2-5g of Transcend Supplements D-Aspartic Acid prior to exercise.
