L-Tyrosine Free Form

500 mg, 100 tablets

L-Tyrosine is a non-essential amino acid and plays an important role in the production of the neurotransmitters dopamine and norepinephrine as well as a precursor for adrenaline.

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.99-107

Cells in the adrenal medulla synthesize and secrete norepinephrine and epinephrine. 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, L-phenylalanine is a 50/50 mixture of its two stereoisomers.
