About this ingredient
Taurine is a naturally occurring sulfur-containing amino acid found in many tissues, particularly skeletal muscle, the brain, heart, and nervous system. Free-form taurine refers to taurine supplied directly as the individual amino acid rather than as part of a protein. Taurine participates in several physiological processes, including cell-volume regulation, membrane stabilization, calcium handling, and bile-acid metabolism. It is widely used in sports and nutritional supplements, with research investigating exercise performance, recovery, muscle function, and metabolic health. Human evidence for performance enhancement is promising but not yet definitive.
