Tyrosine
Tyrosine was first isolated from casein in 1849 and is abundant in insulin as well as the enzyme papain and can be synthesized from the amino acid phenylalanine in the body.
What it is
Tyrosine is a precursor of the neurotransmitters epinephrine, norepinephrine and dopamine, all of them extremely important in the brain and transmits nerve impulses and prevents depression. Dopamine is also vital to mental function and seems to play a role in sex drive.
What it does
Tyrosine is important to overall metabolism; is a precursor of adrenaline, nor epinephrine, and dopamine, which regulate mood and stimulates metabolism and the nervous system.
Tyrosine acts as a mood elevator, suppresses the appetite and helps reduce body fat. It aids in the production of melanin (the pigment responsible for hair and skin color) and in the functions of the adrenal, thyroid, and pituitary glands. It has been used to help chronic fatigue, narcolepsy, anxiety, depression, low sex drive, allergies and headaches.
