Properties
Tyrosine is a nonessential amino acid. The compound is a precursor of catecholamines, which are mediators produced by the adrenal medulla and also by the brain. Thus, the amino acid promotes the production of norepinephrine, adrenaline, dopamine, as well as thyroid hormones.
The main properties of tyrosine are:
- participation in the synthesis of catecholamines by the adrenal glands;
- regulation of blood pressure;
- burning fat in the subcutaneous tissue;
- activation of the production of somatotropin by the pituitary gland - growth hormone with an anabolic effect;
- maintaining the functioning of the thyroid gland;
- protecting nerve cells from damage and improving blood supply to brain structures, increasing concentration, memory and alertness;
- acceleration of the transmission of nerve signals through synapses from one neuron to another;
- participation in the neutralization of the alcohol metabolite - acetaldehyde.
Indications
Tyrosine is prescribed for therapy and prevention:
- anxiety disorder, insomnia, depression;
- Alzheimer's and Parkinson's disease as a component of comprehensive treatment;
- phenylketonuria, in which endogenous synthesis of tyrosine is impossible;
- hypotension;
- vitiligo, while the simultaneous administration of tyrosine and phenylalanine is prescribed;
- insufficiency of adrenal function;
- diseases of the thyroid gland;
- decrease in cognitive functions of the brain.
