Threonine is an essential amino acid. This means the body cannot make it at all, or not in sufficient amounts for good health and it needs to be eaten as part of the diet every day.

Threonine, just like all the other amino acids, is one of the building blocks of all proteins in the body, which not only include muscles, but also all the other proteins required for normal function of the body.
