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.
Directions: Suggested dose is 500 to 1000 mg in the morning or afternoon. More may be necessary for depression or pain. These products are best utilized when taken on an empty stomach mixed with juice or water. Adequate cofactors (vitamins B6 and C) should also be taken if not included with the product.

L-tyrosine 920 mg.
This product contains NO sugar, yeast, wheat, gluten, corn, soy or dairy. Contains NO artificial color, sweeteners, flavors or preservatives.
Warning: 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 over stimulation if taken too close to bedtime. Individuals with the rare metabolic disorder Phenylketonuria should avoid phenylalanine.
