Taurine is a sulfur-containing compound that belongs to the group of amino acid-like substances. Although it is often classified under amino acids, technically it is not a classic amino acid because it is not used in building proteins.

No, taurine is generally not considered essential for adults. However, under certain circumstances it can be considered "conditionally essential."

You need to get essential amino acids through food. Non-essential amino acids can usually be produced by the body itself. Taurine falls into the non-essential category, although it is often mentioned separately because of its unique structure and functions.

Yes, taurine naturally occurs in animal products such as meat, fish, eggs, and milk. Plant-based foods usually contain little to no taurine. As a result, vegetarians and vegans often consume less taurine through their diet.

The taurine in supplements is produced synthetically in laboratories, and is therefore free from animal ingredients. This makes it suitable for vegans and vegetarians.
