L-Taurine is a non-essential amino acid found in high concentrations in the white blood cells, skeletal muscles, the central nervous system and the heart muscles. The addition of vitamin B6 is required for nutrient synthesis from other nutrients, and for maximum absorption and effectiveness in the body. Taurine is essential for bile production in the liver, which is needed for fat digestion and metabolism. Taurine also helps to maintain cholesterol levels, blood pressure and a healthy cardiovascular system.
