Taurine is predominantly found in the retina and heart and is also found in the brain, intestine, skeletal muscles and kidneys. It controls the concentration of intracellular calcium, protects against ischemia-reperfusion injury and possesses blood pressure-lowering properties. Taurine also plays a vital role in bile formation and fat digestion. Deficiency of taurine is associated with development of anxiety, hyperactivity, epilepsy and depression.
