1. Life Extension D-L-Phenyalanine 500 mg, 100 Vegetarian Capsules
Feature
Enhanced mental energy levelsEnhances Mood
Description
L-phenylalanine is an essential amino acid that can be converted to L-tyrosine in the liver. L-tyrosine can be converted in the brain and in the adrenal glands to dopamine, norepinephrine, and epinephrine (adrenaline) hormones that are depleted by stress, overwork and certain drugs. By replenishing norepinephrine in the brain, mental energy levels are enhanced and a feeling of contentment often occurs. The conversion step from L-tyrosine to norepinephrine may be enhanced if the co-factors (vitamins B6 and C) are included.2. NOW L-Phenylalanine 500 mg,120 Veg Capsules

Description
Phenylalanine is an amino acid ranked among the essential amino acids needed to sustain life and critical body functions. It assists in the steady function of the central nervous system. L-Phenylalanine possesses many health benefits, among them, the ability to manage pain, and to control mood swings. On top of that it also heightens overall awareness and it helps regulate appetite. It can be used as a component in the synthesis of many different proteins that are naturally produced in the body. These pain relieving effects that L-Phenylalanine possesses are believed to be connected to the fact that it also helps to produce endorphins in the brain, natural opiates that the body produces on its own.7.
