What is Tyrosine?

Tyrosine is the non-essential amino acid precursor for dopamine, norepinephrine and epinephrine. Tyrosine hydroxylase converts tyrosine into the dopamine precursor L-DOPA; BH4, Vitamin D and iron are cofactors for that enzymatic activity.

Low levels:

  • Low levels of tyrosine have been associated with hypothyroidism, depression and blood pressure disorders.
  • If phenylalanine is normal or high (barring PKU), iron, vitamin C, and niacin supplementation might be indicated to help convert phenylalanine to tyrosine.

High levels:

  • Increased tyrosine may exacerbate migraine headaches and hyperthyroid conditions.
  • Elevated tyrosine levels may occur due to supplementation (phenylalanine or tyrosine), heritable enzyme defects, or liver disease.
  • High levels may indicate an inability to utilize tyrosine properly, perhaps because of low levels of enzyme co-factors such as iron, copper, iodine, B6, and vitamin C.
