An amino acid which is a building block for several important mood-enhancing brain chemicals (neurotransmitters) such as serotonin, dopamine, and noradrenaline. Tyrosine is a precursor of thyroid hormones and it also assists in the function of the glands responsible for making and regulating hormones, including the adrenal, thyroid and pituitary glands. Tyrosine is, therefore, useful to improve thyroid function, for stress management, to increase low energy levels, for increased alertness, as an appetite suppressant, and to increase sexual desire.
