L-Tyrosine

For anxiety L-Tyrosine is considered a "conditionally essential" amino acid, due to the fact that there are circumstances where the body cannot produce enough of it to meet physiological needs. Tyrosine is important for the production of catecholamines, including epinephrine, norepinephrine, and dopamine. Since tyrosine is involved in the production of the stress hormones epinephrine and norepinephrine, during times of stress, the body may not be able to produce enough tyrosine from phenylalanine to meet dietary needs. It is also involved in the function of organs responsible for producing and regulating hormones, including the adrenal, thyroid, and pituitary glands. Furthermore, it is involved in the structure of nearly every protein in the body.
