L-Tyrosine

L-Tyrosine is a semi-essential amino acid, however essential under certain metabolic circumstances like phenylketonuria. It improves concentration, mood, and attention, reduces appetite and delays fatigue.

L-Tyrosine is used in rejuvenating or reenergizing formulas. Tyrosine is an amino acid that is the precursor to the neurotransmitters norepinephrine and dopamine, which regulate mood. Norepinephrine also suppresses appetite and helps to reduce body fat and, with iodine, forms active thyroid hormones. Deficiency can lead to low mood (hence to poor concentration), low blood pressure and body temperature, and restless leg syndrome. Tyrosine is involved in the metabolism of the amino acid phenylalanine, and has been used successfully for headaches, stress reduction, anxiety, and to support individuals dealing with chemical addictions. Persons taking MAO (monoamine oxidase) inhibitors for depression should not take tyrosine, because the combination may lead to sudden, dangerous rise in blood pressure.

L-Tyrosine is a direct precursor to Thyroxine, a primary thyroid hormone, as well as Adrenaline and Nor-adrenaline. Thyroxine has been found to increase metabolic rate and control growth rate. L-Tyrosine is a necessary amino acid in the production of neurotransmitters including epinephrine, norepinephrine, and dopamine. L-Tyrosine also appears to have a mild stimulatory effect on the central nervous system. Tyrosine, like phenylalanine, is a an amino acid that is the precursor to the neurotransmitters norepinephrine and dopamine, which regulate mood. Norepinephrine also suppresses appetite and helps to reduce body fat and, with iodine, forms active thyroid hormones.
