L-phenylalanine is an essential amino acid which can be converted to L-tyrosine by a complex biochemical process which takes place in the liver. 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, some forms of depression are alleviated, 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 brain’s 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 a precursor of two thyroid hormones.
Dosage
and use: Adequate cofactors (vitamins B6 and C) should also be taken if not included with the product. Caution: Cancer patients should avoid taking L-phenylalanine and L-tyrosine. Certain cancers, such as melanoma, depend on these amino acids to fuel their growth. Supplemental use of L-phenylalanine and L-tyrosine may raise or normalize blood pressure. Insomnia may occur from overstimulation if taken too close to bedtime. Warning: These products are not intended to diagnose, treat, cure or prevent any disease. Please consult with a healthcare professional before starting any diet or exercise program. Some of these products are not recommended for individuals under the age of 18.
