The main sources of taurine powder can be summarized into two aspects:

Endogenous synthesis:

Taurine is a sulfur-containing amino acid found widely in animal tissues and organs, existing mainly in free form in interstitial and intracellular fluids. In the human body, taurine can be synthesized from cysteine through the action of cysteine sulfinic acid decarboxylase. Adults generally do not require additional taurine in their diet as long as liver function is normal, allowing for endogenous synthesis.

Dietary sources:

Dietary taurine primarily comes from animal-based foods, particularly marine animals. For instance, fish and nocturnal birds such as owls, which prey on rodents, benefit from the high taurine content found in these animals. In infants, especially premature infants, whose enzymatic systems are not fully developed, they rely on dietary intake for adequate taurine supply. Breast milk contains a high concentration of taurine, particularly in colostrum.

Taurine powder is primarily sourced from endogenous synthesis and dietary intake. While adults mainly rely on endogenous synthesis, infants, especially premature infants, require dietary intake to meet their growth and developmental needs.
