A member asked:

What is the difference between tyrosine and synthroid (thyroxine)?

A doctor has provided 1 answer

Synthroid (thyroxine): Tyrosine is an amino acid. Synthroid is thyroxine, a hormone based on the amino acid tyrosine but extensively modified. They are two different things--synthroid treats hypothyroidism, tyrosine does not.
