Because l-tyrosine is also a precursor to the thyroid hormone thyroxine (also known as T4) supplementation may have a positive effect on thyroid hormone levels which may contribute to an increased metabolic rate. Many supplement retailers use the fact that tyrosine is a T4 precursor to make claims about its fat burning prowess. Unfortunately, clinical data validating l-tyrosine's thyroid-and-metabolism boosting characteristics is in darn short supply.
Nonetheless, considering its effect on mood and mental acuity, it's not too surprising to find l-tyrosine included in many popular fat burners, and strength enhancement products targeted to body builders.

Function:
Aside from being a proteinogenic amino acid, tyrosine has a
special role by virtue of the phenol functionality. It occurs in
proteins that are part of signal transduction processes. It
functions as a receiver of phosphate groups that are transferred
by way
of protein kinases (so-called receptor tyrosine kinases).
Phosphorylation of the hydroxyl group changes the activity of the
target protein.
Medical use:
Tyrosine is a precursor to neurotransmitters and increases plasma
neurotransmitter levels (particularly dopamine and
norepinephrine)but has little if any effect on mood.The effect on
mood is more noticeable in humans subjected to stressful
conditions
