You have got questions about the product

  • Precursor for the synthesis of key hormones and neurotransmitters
  • Supports the functioning of the nervous system and shows a neuroprotective effect
  • Excellent support for physically and mentally active people
  • Promotes the proper course of metabolic processes

MZ Tyrosine is a dietary supplement containing L-tyrosine in convenient capsules. The preparation enhances the functioning of the nervous and endocrine systems and supports the appropriate metabolic rate. L-tyrosine is also great as an addition to the diet of athletes due to its indirect stimulating, slimming and pro-cognitive effects.

L-tyrosine is one of the twenty protein amino acids found in nature. For humans, it is an endogenous amino acid – synthesized by the body from phenylalanine. Nevertheless, L-tyrosine supplementation is often recommended because of its positive effect on cognitive functions, metabolic processes, and hormone synthesis, especially in people at risk of deficiency of this important amino acid.

Precursor for hormones and neurotransmitters
L-tyrosine is a substrate for the synthesis of thyroid hormones (T3 and T4) and catecholamines (adrenaline, dopamine, noradrenaline). Its normal level in the body is, therefore, crucial to maintain the proper concentration of these hormones. T3 and T4 are responsible, among others, for the proper occurrence of all metabolic processes, which is especially important for active people who want to work on their body sculpture. Thyroid hormones are also important in terms of calcium and phosphate metabolism as well as well-being and motivation to act.

The above-mentioned catecholamines are neurotransmitters that are crucial for the proper functioning of the nervous system. They also provide stimulation, intensify the acquisition of energy from adipose tissue, and regulate important parameters for life, such as blood pressure, heart rate or glucose concentration.

Support for athletes and blue-collar workers
L-tyrosine exerts neuroprotective properties and – through the neurotransmitters synthesized from it – positively affects normal cognitive functions such as memorizing, learning, concentration and analytical processes. Furthermore, it also has a positive effect on mood and energy levels and may reduce the occurrence of depression.

Catecholamines formed from L-tyrosine are particularly important for athletes during periods of increased activity. They prepare the body for physical effort and allow greater focus. L-tyrosine itself may contribute to the improvement of muscle contractility as well as their strength and endurance.

To sum up, MZ Tyrosine is an excellent source of an amino acid that supports hormonal balance and the proper functioning of the nervous system. This preparation is recommended mainly for people who want to keep their metabolism strong and those who perform intensive physical or mental work.

Tyrosine - endogenous amino acid (synthesized within the body), one of the 22 protein amino acids building. It occurs naturally in animal food products (eggs, dairy, meat). If the deficiency, it can be synthesized by hydroxylation of phenylalanine, capable of being converted to tyrosine in the liver. It is a precursor of neurotransmitters: dopamine (the group of catecholamines, participating in the processes occurring in the nervous system, causing muscle coordination and participates in the synthesis of many hormones) and noradrenaline (counteracting stress, stimulating the heart and circulatory system, and increasing glycogenolysis and lipolysis participating in the processes of energy transformations). Tyrosine is a precursor of thyroid hormones responsible for the rate of change in metabolic processes and pigment (melanin). In the supplementation, preparations containing tyrosine are used in programs reducing body fat (weight loss), improve mood and are stimulants.
Dosage: Customarily 500-2000 mg per day.
