L-Taurine by SciFit is a nonprotein amino acid. It is the end product of L-cysteine metabolism and the principle free intracellular amino acid found in human tissue. The most understood role of L-Taurine in humans is its involvement in the formation of Taurine bile acids conjugates in the liver, which are essential for micelle formation and fat absorption. Furthermore, L-Taurine is involved in pre/post-natal nervous and visual system development. L-Taurine also has antioxidant, membrane stabilization activities and may decrease insulin resistance.
L-Taurine is the second most abundant free amino acid in muscle tissue. Taurine may exhibit insulin like effects and play a prominent role in cell volumizing .
