Taurine

Taurine is a sulfur-containing amino acid found abundantly throughout the body, particularly in the brain, heart, retina, and skeletal muscle. Unlike most amino acids, it is not incorporated into proteins but instead functions as a free amino acid involved in a wide range of physiological processes. Research suggests taurine plays important roles in bile salt formation, cell membrane stabilization, calcium signaling, and osmoregulation, which supports its connection to hydration and nerve function. Studies indicate it may help support healthy blood pressure levels, cardiovascular function, and retinal health, while emerging research in animal models has explored its potential involvement in aging-related decline. Taurine is produced naturally in the body and is also obtained through dietary sources such as meat, fish, and dairy, with L-taurine being the most widely studied supplemental form.
