L-tyrosine is an amino acid precursor for synthesis of the neurotransmitters norepinephrine and dopamine.* By improving the rate of neurotransmitter synthesis, L-tyrosine stimulates the central nervous system.* It appears to function as an adaptogen by relieving physical symptoms of stress, such as mood swings.* Chronically stressed individuals may not efficiently convert phenylalanine to L-tyrosine, making supplementation with L-tyrosine desirable.*
L-tyrosine also serves as a precursor for the thyroid hormone thyroxine and melanin, the pigment responsible for skin and hair color and protection against harmful ultraviolet rays.* In addition, L-tyrosine stimulates growth hormone and is involved in adrenal and pituitary function.* L-tyrosine is also a powerful antioxidant, scavenging and neutralizing free radicals and inhibiting fat oxidation.*
