Tyrosine, also known as 4-hydroxyphenylalanine or L-Tyrosine, is a nonessential amino acid that the body synthesizes from another amino acid called phenylalanine. It is named from the Greek tyros, which translates to mean “cheese,” because it is found in casein protein in cheese and other dairy products. Other natural food sources include fish, avacados, bananas, lima beans, almonds, peanuts, and sunflower and pumpkin seeds.

NOW® L-Tyrosine is a non-essential amino acid and plays an important role in the production of the neurotransmitters dopamine and norepinephrine, as well as a precursor for adrenaline.In addition, because L-Tyrosine is necessary for the synthesis of thyroid hormone and epinephrine (adrenaline), L-Tyrosine supports healthy glandular function and stress response.
