Taurine is a nutritive support component present in a variety of goods. The FDA authorized taurine supplements in 1984, and they are hypertonic injections made of cristalline amino acids. Over the counter (OTC) taurine supplements are available but they do not have the same quality as those sold by health food stores and pharmacies under various names such as Taurultame, Cytosport, Carnipure, and GlucoTech. OTC products contain either purified taurine or glucosamine plus taurine, while high-quality supplements also include chondroitin, hyaluronic acid, and vitamin C. Taurine is found in many foods including meat, fish, dairy products, eggs, beans, vegetables, and fruits. Milk contains approximately 1-2% taurine by weight. Other sources include wheat germ, brewer's yeast, and soybean oil. Taurine is one of the most abundant amino acids in human blood plasma with an average concentration of 0.4 mM. It is also found in large quantities in bile salt solutions used to wash raw meat prior to cooking. Taurine is essential for humans because we cannot make it ourselves. The main source of taurine for humans is food, especially meats. Other sources include milk products, beer, and wine.
