D-Aspartic acid,China price supplier

 D-Aspartic Acid ist the d-form of the amino acid aspartic acid. The l-form of all proteinogenic amino acids build tissues, the d-form is not a building block but a signaling molecule. In specific tissues of the body (testes, pituitary gland, and hypothalamus, all responsible for hormone production), the non-essential amino acid l-aspartic acid (l-form) is converted by a d-aspartate racemase and becomes the d-form, a racemate isomer of the l-form. The d-aspartic acid supplements contain thus the form of the aspartic acid responsible for increasing testosterone levels.
