L-Tyrosine, Free Form Amino Acid, 100 Tablets, 500mg, L Tyrosine, From Source Natural
L-Tyrosine can be converted by neurons in the brain to dopamine and norepinephrine (noradrenaline), hormones, which are depleted by stress, overwork and certain drugs. By replenishing norepinephrine in the brain, mental energy levels are enhanced and a feeling of contentment often occurs. Because of the liver conversion necessary for L-phenylalanine to have these effects, L-tyrosine is often faster acting. In addition, the conversion step from L-tyrosine to norepinephrine may be enhanced if the cofactors (vitamins B6 and C) are included.
Some of the norepinephrine will also be converted to epinephrine (adrenaline) in the brainís adrenal medulla by use of S-adenosylmethionine (SAMe) as a methylating agent. Since both norepinephrine and epinephrine can cause smooth muscle (arterial) contraction, care with blood pressure should be taken when supplementing L-phenylalanine or L-tyrosine.
L-tyrosine is also a precursor of two thyroid hormones. D-phenylalanine is unique among amino acids because the D-form (normally not found in life) has biological activity that is different from its L-stereoisomer. D,L-phenylalanine is a 50/50 mixture of the two stereoisomers.
L TYROSINE is an essential free form amino acid, which rapidly crosses the blood-brain barrier. It is a precursor for the neurotransmitters dopamine, norepinephrine, and epinephrine, for thyroid hormones, and for enkephalins, special peptides that subdue messages of physical discomfort. Tyrosine is also a constituent of protein amino sugars (glycosaminoglycans) and amino lipids (glycolipids), special compounds that have important roles throughout the body.

About Source Naturals
Source Naturals was created in 1982 by C.E.O Ira Goldberg to support each individualís potential to enjoy optimal health. At that time, the kind of nutritional formulations he envisioned Ė for the maintenance of well-being and the enhancement of life Ė simply didnít exist. The idea of combining many nutrients, herbs and nutraceuticals in one formulation, though common today, was then a rarity. Source Naturals pioneered the concept with Wellness Formulaģ, now the industryís #1 immune support product.
