L-Tyrosine plays an important role in the central nervous system, the thyroid, and the adrenal glands.
It is an amino acid precursor for the synthesis of the brain-friendly neurotransmitters norepinephrine and dopamine.
- By improving the rate of neurotransmitter production and stimulating the central nervous system, it helps relieve the physical symptoms of stress, such as mood swings.
- Chronically stressed individuals might not efficiently convert phenylalanine to tyrosine, which makes supplementation desirable.
- Serves as a precursor for the thyroid hormone thyroxine and for melanin, the pigment that protects against harmful ultraviolet rays.
- Stimulates growth hormone, is involved in adrenal and pituitary function, and is a powerful antioxidant, neutralizing free radicals and inhibiting fat oxidation.
