Swanson L-Tyrosine is a dietary supplement containing an amino acid - L-Tyrosine at the dose of 500 mg. The preparation primarily aims at supporting energy metabolism of the organism and optimization of the functioning of the nervous system, positively influencing concentration and memorization processes.

L-Tyrosine - belongs to the group of protein endogenous amino acids which can be synthesized by the human organism. For the synthesis of tyrosine, a proper amount of an exogenous amino acid - phenylalanine is essential. Therefore, in case of the insufficient supply of phenylalanine, the organism is prone to unbeneficial tyrosine deficiency. It is believed that diet and supplementation cover the majority of the need for this important amino acid.

L-Tyrosine takes part in the biosynthesis of the main catecholamines, functioning as stimulating neurotransmitters and hormones in the sympathetic system - adrenaline, noradrenaline and dopamine. Tyrosine constitutes a key precursor for their synthesis, undergoing the reactions of hydroxylation and decarboxylation. By conditioning optimal concentration of these neurotransmitters, tyrosine contributes to maintaining balance in the nervous system.

Adrenaline is called the “fight or flee” hormone. It conditions the regulation of the organism’s response to stress, increasing energy level, causing the state of stimulation and accelerating energy metabolism. By phosphorylating lipases, it activates them and at the same time it stimulates burning fat. It also mobilizes the processes of glycogenolysis.

Noradrenaline mobilizes the organism to act and at the same time it increases alertness. It causes the growth of concentration and the improvement of memory. It is an important neurotransmitter from the point of view of maintaining emotional stability - some atypical antidepressants are based on the mechanism of increasing the concentration of noradrenaline in the synaptic cleft.

Dopamine is a neurotransmitter conditioning emotional processes, movement processes and muscle coordination and it stimulates the reward system in the brain. A classic ailment, in which dopamine deficiency appears is Parkinson’s disease. Moreover, in the hypothalamus, dopamine plays regulatory functions for hormone secretion, i.a. prolactin and gonadotropins.

L-tyrosine is a precursor for the synthesis of thyroid hormones in the period of iodizing. Thyroid hormones (triiodothyronine, thyroxine and calcitonin) regulate metabolism and calcium-phosphorus balance of the organism, conditioning proper development of the central nervous system, mineralization of bones and influencing well-being and optimal energy level. Deficiency of thyroid hormones is the cause of hypothyroidism and Hashimoto's thyroiditis. Therefore, it is worth paying attention to the proper supply of tyrosine, especially in these ailments, as it may turn out to be helpful in restoring proper level of thyroid hormones.

To sum up, Swanson L-Tyrosine is a dietary supplement, providing the amino acid, essential for the optimal functioning of the organism. The product is especially recommended as support in the therapy of hypothyroidism or Hashimoto's thyroiditis, in the periods of increased physical and intellectual effort, for people who exercise, lead a stressful lifestyle, in energy drops and problems with memory and concentration.
