Morning
Taurine is a sulfur-containing amino acid found in high concentrations throughout the brain, heart, retina, and skeletal muscle. Unlike most amino acids, it is not incorporated into proteins but instead exists freely in tissues where it participates in numerous physiological processes. It is naturally obtained through meat and seafood consumption, though endogenous synthesis from cysteine can be insufficient under metabolic stress.
