Taurine is a naturally occurring amino acid found in various tissues throughout the body, particularly in the brain, heart, and muscles. It plays a crucial role in several biological processes, including bile salt formation, osmoregulation, and the modulation of calcium levels in cells. Unlike other amino acids, taurine is not used to build proteins but is essential for maintaining overall health. Taurine is commonly found in animal-based foods, such as meat and fish, and is also available as a dietary supplement. It is often included in energy drinks due to its potential benefits for exercise performance and recovery. While the body can produce taurine from other amino acids, supplementation may be beneficial for certain individuals, particularly those with specific dietary restrictions.
