Tyrosine is a dietary supplement containing a high dose of L-tyrosine and taurine. The product is intended for people who are exposed to increased strain, both mental and physical. Tyrosine is a precursor of important neurotransmitters such as dopamine and norepinephrine, compounds of elementary importance for the proper functioning of the whole system. Dopamine belongs to catecholamines, takes part in emotional processes as well as in muscle coordination and hormone synthesis. Norepinephrine secreted in response to stress stimuli, affects the circulatory system and energy processes (increases glycogenolysis, lipolysis). Tyrosine is also a precursor of melanin - pigment (dye), found in the dermis and epidermis. Tyrosine stimulates, increases alertness and concentration, counteracts physical and mental fatigue, supports brain function and increases resistance to stress. In addition, it is used to reduce body fat.
