Taurine

• Taurine is a non-protein, non-essential amino acid which functions as a calmer of the central nervous system due to its inhibitory action.
• Taurine is the second most abundant amino acid in muscle tissue, with glutamine being the first.
• But it's not actually part of the muscle tissue. Rather, it's primarily in the amino acid pool within each muscle cell and is, in fact, not even a component of protein but remains free in our bodies.
• It does, however, act as the building block of other amino acids.
• Many experts consider taurine conditionally essential because intense exercise as well as other types of stress deplete the nutrient.
