Supports thyroid and adrenal function and promotes a positive mental state*
L-Tyrosine promotes the body's production of neurotransmitters (brain chemicals) and thyroid hormones, and supports healthy stress management.* It also helps maintain healthy adrenal function.*
L-tyrosine is a conditionally essential amino acid because under normal conditions the body synthesizes sufficient quantities of it from phenylalanine. For individuals who have phenylketonuria, however, a severe deficiency in the enzyme phenylalanine hydroxylase prevents the conversion of phenylalanine to tyrosine, making tyrosine an essential amino acid for this population. Tyrosine is incorporated into proteins and is a precursor for the synthesis of thyroxin, melanin, and the neurotransmitters dopamine and norepinephrine. Food sources of tyrosine include fish, soy products, poultry, eggs, dairy products, lima beans, almonds, peanuts, sesame seeds, pumpkin seeds, wheat germ, oats, avocados, and bananas.
Although tyrosine has numerous mechanisms of action, perhaps its most clinically significant one is its role as a precursor to norepinephrine and dopamine synthesis. By improving the rate of neurotransmitter synthesis, tyrosine stimulates the central nervous system, which improves mood.* Tyrosine also serves as a precursor for melanin, the pigment responsible for skin and hair color that provides protection against harmful ultraviolet rays, and for the thyroid hormone thyroxine.* Tyrosine is involved in adrenal and pituitary function, and it also appears to function as an adaptogen by relieving physical symptoms of stress.* Because of its phenolic structure, tyrosine is a powerful antioxidant, scavenging and neutralizing numerous free radicals and inhibiting lipid peroxidation.*
