L-Phenylalanine is an essential amino acid that converts to Tyrosine, helping to elevate catecholamine neurotransmitters. It has been used in the treatment of depression, and may be helpful with those with Parkinson's Disease 8,12 and Multiple Sclerosis. It also helps in appetite suppression. * D-Phenylalanine increases endorphin production and is recommended for chronic pain endurance.

WHAT IS L-PHENYLALANINE?
L-Phenylalanine is an essential amino acid; therefore, it cannot be synthesized from other amino acids and must be obtained in the diet from food sources or through supplementation. The primary sources of foods that contain Phenylalanine are meats and milk products, although smaller amounts are found in oats and wheat germ. It can cross the blood brain barrier, thus effecting brain chemistry. As the precursor to Tyrosine, it is necessary in the function of catecholamine neurotransmitters epinephrine, norepinephrine, dopamine and Tyramine, as well as the manufacturing of thyroxine and tri-iodothyronine in the thyroid gland. Vitamins and minerals are necessary for proper metabolism, and B6, B3, vitamin C, copper and iron are required. Because of its effects on neurotransmitters, supplementation can help alter mood and it has been used as an anti-depressive. It can effect alertness and may be useful in neurological problems such as Parkinson's disease and MS. Phenylalanine is also involved in melanin production, and those who can not convert Phenylalanine to Tyrosine due to a heredity problem have a metabolic defect called phenylketonuria (PKU).

Each capsule contains:

500mg Pure Phenylalanine U.S.P.

DIRECTIONS: Take 1- 2 capsules twice daily on an empty stomach, with a full glass of water or fruit juice. B-6 and Vitamin C and other vitamins and minerals are necessary for proper metabolism; therefore it is necessary to also take a daily vitamin-mineral supplement and B complex, and B-Complete and Montiff Vita-Minz Plus are recommended.

CAUTION: L-Phenylalanine can raise blood pressure in some individuals; therefore, it should not be taken for those with Hypertension or anxiety. It should also not be taken by those with preexisting melanomas, pregnant or lactating women, those with phenylketonuria (PKU) or individuals who are taking MAO inhibitor drugs.
