Product details "L-Tyrosine"

L-tyrosine is an amino acid that can be converted to dopamine, norepinephrine and epinephrine (adrenaline). These hormones are often reduced by stress, overwork and certain drugs and need to be replenished. Norepinephrine, for example, enhances mental energy levels that often induce a feeling of contentment. The conversion step from L-tyrosine to norepinephrine may be enhanced if the co-factors (vitamins B6 and C) are included.  

L-tyrosine also functions as a precursor to thyroid hormones, encephalins and melanin.

Cells in the adrenal medulla synthesise and secrete norepinephrine and epinephrine. Since both of these hormones can cause smooth muscle (arterial) contraction, care with blood pressure should be taken when supplementing with L-tyrosine.

Caution

Cancer patients should avoid taking L-phenylalanine and L-tyrosine. Certain types of cancer, such as melanoma, depend on these amino acids to fuel their growth.

Supplemental use of L-phenylalanine and L-tyrosine may raise or normalise blood pressure. Insomnia may occur from over-stimulation if taken too close to bedtime. Individuals with the rare metabolic disorder phenylketonuria should avoid phenylalanine. Those suffering from migraine headaches should also avoid L-phenylalanine and L-tyrosine, because they form tyramine, a substance that may trigger migraines.
