Commonly found in a variety of meats, dairy products and eggs, the amino acid Taurine can be obtained from the diet in minimal amounts.  Unfortunately, physical activity depletes our Taurine reserves faster than most people can produce it.  As a result, vegetarians, athletes and individuals lacking meat in their diets are at the greatest risk for deficiency, and stand to benefit the most from supplementing this life-crucial nutrient.  As a catalyst to general amino acid efficiency as well as one of the most abundant amino acids in the human body, Taurine has a number of useful health benefits.  As a key constituent of bile acids, it helps the body absorb other nutrients with greater ease while moderating healthy cellular activity.  It has also been known to exhibit antioxidant properties that may help protect macular regions of the eye.  At the end of the day NOW Taurine Pure Powder is an outstanding all-around supplement.
