Tyrosine is a nonessential amino acid the body makes from another amino acid called phenylalanine. It is a building block for several important brain chemicals called neurotransmitters, including epinephrine, norepinephrine, and dopamine. Neurotransmitters help nerve cells communicate and influence mood. Tyrosine also helps produce melanin, the pigment responsible for hair and skin color. It helps in the function of organs responsible for making and regulating hormones, including the adrenal, thyroid, and pituitary glands. It is involved in the structure of almost every protein in the body. Low levels have been associated with low blood pressure, low body temperature, and an underactive thyroid. Use for depression, anxiety, alcoholism, drug withdrawal, pituitary, thyroid, and adrenal hypo-function.
