Description

L-Tyrosine is a nonessential amino acid (protein building block) that the body synthesizes from the amino acid phenylalanine. Tyrosine is important for the structure of almost all proteins in the body.

L-Tyrosine, through its effect on neurotransmitters, may affect several health conditions, including Parkinson’s disease, depression, and other mood disorders. Studies suggest that tyrosine may help people with depression. Preliminary findings indicate a beneficial effect of tyrosine, along with other amino acids, in people affected by dementia, including Alzheimer’s disease. Due to its role as a precursor to norepinephrine and epinephrine (two of the body’s main stress-related hormones) tyrosine may also ease the adverse effects of environmental, psychosocial, and physical stress.

L-Tyrosine is also a direct precursor to thyroxin, a primary thyroid hormone, as well as adrenaline and nor-adrenaline. Thyroxin has been found to increase the metabolic rate and control the growth rate.

L-Tyrosine is a necessary amino acid in the production of neurotransmitters including epinephrine, norepinephrine, L-dopa and dopamine. L-Tyrosine also appears to have a mild stimulatory effect on the central nervous system. Patients with a thyroxin deficiency have symptoms including excess weight gain, cold hands and feet, and decreased basal metabolism. L-Tyrosine has been found to assist in optimizing thyroid hormone levels, and increased mood, concentration, and productivity.

L-Tyrosine should be taken as recommended by a healthcare professional.
