L-Tyrosine is classified as a conditionally essential amino acid. Under most circumstances the body can synthesize sufficient L-tyrosine, principally from L-phenylalanine, to meet its physiological demands. However, there are conditions where the body requires a dietary source of the amino acid for its physiological demands.  In addition to being involved in protein synthesis, L-tyrosine is a precursor for the synthesis of the catecholamines epinephrine, norepinephrine and dopamine, the thyroid hormones thyroxine and triiodothyronine, and the pigment melanin.  Our L-tyrosine is flavoured with fructose to improve patient compliance and is catalyzed with the T J Clark phytogenic mineral catalyst for superior bioavailability.

Pharmacology and Research of Active Ingredients:
  • L-Tyrosine exhibits effective antidepressant activity.  The mechanism of L-tyrosine’s antidepressant activity may be accounted for by the precursor role of L-tyrosine in the synthesis of the neurotransmitters norepinephrine and dopamine. Elevated brain norepinephrine and dopamine levels are thought to be associated with antidepressant effects.  L-Tyrosine is a component of enkephalin, and has been shown to regulate blood pressure and stimulate prolactin secretion.
  • Through the production of the catecholamines, particularly adrenalin, L-tyrosine is thought to play a role in increasing the activity of brown fat cells, thus increasing fat utilisation.  Tyrosine supplementation can reduce the fatigue and cognitive decline experienced during prolonged stress.
  • Phytogenic Mineral Catalyst – Our Polyfloramin™extracts contain up to 72 trace elements for enhanced bioavailability, assimilation and synergy of the active ingredients contained in our Tyrosine formula.
