Taurine powder is a sulfur-containing non-protein amino acid that is abundantly present in the human body, mainly in a free form in interstitial fluid and intracellular fluid. As an important substance in the body, taurine powder performs various physiological functions, such as maintaining osmotic pressure balance, ensuring normal visual function, regulating cellular calcium balance, acting as an antioxidant, modulating nerve transmission, and promoting lipid digestion and absorption.

The levels of taurine powder in the human body are influenced by several factors, including age, gender, and dietary habits. Some foods also contain taurine, such as seafood and animal organs, making it possible to obtain a certain amount of taurine through diet.

Despite the many important roles of taurine powder in the human body, this does not mean that people need to supplement it in large quantities. Under normal circumstances, the body can synthesize enough taurine or obtain it from food to meet physiological needs. Only in special cases, such as certain diseases or malnutrition, might additional taurine supplementation be necessary.
