(L)-Tyrosine is a nonessential amino acid that is synthesized in the body from phenylalanine. As a building block for several important brain chemicals, tyrosine is required to make epinephrine, norepinephrine, serotonin, and dopamine, all of which work to regulate mood. Therefore, deficiencies in tyrosine have been associated with depression. In addition, tyrosine aids in the production of melanin (pigment responsible for hair and skin color) and in the function of organs in the body responsible for making and regulating hormones,...
