Is Threonine Vegan?

Threonine is one of the essential amino acids required for protein synthesis in the human body. Unlike non-essential amino acids, threonine cannot be synthesized by the body and must be obtained through diet. It is involved in various bodily functions, including immune response, and is a precursor for other amino acids like glycine and serine. Threonine is present in high-protein foods such as meats, dairy, eggs, as well as plant-based sources like legumes, nuts, and seeds.
