Taurine

Taurine is a conditionally essential, sulfur-containing amino acid and the most abundant amino acid in the heart. Taurine supplementation has been shown to benefit the production of nitric oxide in the vascular endothelium, which is essential to optimal blood flow, maintaining already normal blood pressure, and overall cardiovascular function.
Taurine also acts as an antioxidant.* In the liver, taurine is combined with bile acids, which results in increased cholesterol solubility and excretion, thus helping to maintain healthy cholesterol levels already in the normal range.* Taurine's involvement in bile acid formation facilitates fat digestion, fluid regulation, detoxification of environmental toxins, regulation of cellular calcium, and regulation of nerve excitability.
