"Taurine is a conditionally essential free-form amino acid that is the most abundant free amino acid in many tissues and participates in a variety of metabolic processes. Taurine is found at high levels in the heart and skeletal muscle, white blood cells, the central nervous system, and is a building block for all other amino acids. Taurine works synergistically with any form of Creatine. Taurine is different than most other amino acids because it is not incorporated into proteins but it does play many roles in the body, including bile acid conjugation, detoxification, membrane stabilization, osmoregulation, and modulation of excitatory neurotransmission and intracellular calcium levels.
