L-Tyrosine has many and varied functions. It is needed to make epinephrine, norepinephrine and dopamine; all of which work to regulate mood. It aids in the production of melanin, in the regulation of the adrenal, thyroid and pituitary glands, and is involved in the synthesis of enkephalins, the body’s natural pain relievers. L-Tyrosine should not be used with MAO inhibitors. *

What is L-Tyrosine?

Tyrosine is a non-essential amino acid, but natural production may be affected by the intake of its precursor, essential amino acid, phenylalanine. The metabolism of tyrosine is a precursor for the production of catecholamines (epinephrine, norepinephrine, and dopamine), all of which help to regulate mood, focus, and cognitive function. Tyrosine is also a component of enkephalins (or endorphins), which are natural pain relievers.

Activated vitamin B-6 has been added as an aid to amino acid metabolism.

 

How does L-Tyrosine Work?

In the body, L-tyrosine is converted into the compound L-DOPA by tyrosine hydroxylase. L-DOPA is then decarboxylated into dopamine, which can be oxidized into norepinephrine and then converted to epinephrine depending on the body’s need for each of these neurotransmitters[1]. Although technically a “non-essential” amino acid, supplementation of tyrosine has been shown to increase both plasma tyrosine and brain dopamine production [2]. 

As a precursor for the production of both dopamine and norepinephrine, tyrosine supplementation may improve cognitive flexibility and counteract or reverse cognitive decline through the rescue of neurotransmitter function [3,4]. Tyrosine’s support of cognition may be most pronounced in acutely stressful situations such as extreme cold, high altitude, and sleep deprivation [3,4]. It may also help to protect against neurological decline in elderly patients with dementia. As dementia progresses, catecholamine levels decrease, and catecholamines have an antioxidant effect in the brain, which may, in fact, be neuroprotective [5].

L-tyrosine is also a component of enkephalins (or endorphins), natural pain relievers that activate pathways resulting in simultaneous dopamine release and locomotor activation [6]. The role of L-tyrosine is essential to the hypothalamo-pituitary-adrenocortical (HPA) axis, which controls adrenal glucocorticoid stress response, as well as regulation of the adrenal, thyroid, and pituitary glands [7].

 

What are the Suggested Uses for L-Tyrosine?

  • As a precursor to energizing neurotransmitters, L-tyrosine promotes a positive mood, focus, and mental clarity*
  • Plays a role in the body’s regulation of and reaction to stress as a component of endorphin production and critical to the hypothalamo-pituitary-adrenocortical (HPA) axis.
