Tyrosine is a conditionally essential amino acid–amino acids being the building blocks of proteins. This amino acid is conditionally essential because the body can normally produce it using other essential amino acids, but it may require supplementation when a person is ill. Tyrosine is the precursor of melanin, epinephrine, and thyroid hormones.

Health considerations

Since this amino acid can be produced by modifying existing essential amino acids in the body, consumption of tyrosine is not technically required unless one is fighting an illness. Though consumption of this amino acid is still strongly suggested, so as to allow the essential amino acids to fulfill their other purposes in the body.
