A nonessential amino acid or protein building block, tyrosine is derived from the amino acid phenylalanine.

It serves as a precursor to a range of neurotransmitters and molecules.

And it is used in

  • Protein synthesis
  • Mood support, through its role in the production of Epinephrine, norepinephrine, and dopamine
  • production
  • Helping to regulate thyroid hormone synthesis

Your body can synthesize tyrosine from the amino acid phenylalanine to meet the body's demands; however, there are conditions, such as Phenylketonuria, that demand a dietary source.


Tyrosine is used as a precursor to thyroid hormones tyroxine and triiodotyroonine, which support thyroid function.


Tyrosine is a critical building block for such neurotransmitters as epinephrine, norepinephrine, and dopamine, which help regulate mood and stimulate the metabolism and nervous system.

Dopamine supports numerous functions in your cardiovascular, endocrine, and central nervous systems, and it may be transformed into norepinephrine or epinephrine.

Reduced Tyrosine leads to decreased production of norepinephrine and dopamine, which can lead to low mood states.

Supplementing with L-Tyrosine may help promote a balanced mood.


Some scientists say the brain may not be able to produce tyrosine from phenylalanine when it is under stress.

Under such stress, epinephrine, norepinephrine, and dopamine production may also be affected.

However, supplementing with L-Tyrosine may help the body to better cope with stress.
