Essential amino acid L-phenylalanine


DIUCAPS provide a therapeutic dose of essential amino acid L-Phenylalanine which acts as a biological precursor to neurotransmitters dopamine and norepinephrine (NE), and helps support normal levels of gut hormones which control appetite and satiety.

Studies have referred to L-Phenylalanine as a “potent releaser” of cholecystokinin (CCK), a hormone that can produce feelings of food satisfaction and fullness. The result is reduced desire for food and less food intake.

L-Phenylalanine can be converted in the brain and in the adrenal glands to the neurotransmitters dopamine, norepinephrine, and epinephrine (adrenaline) 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 from L-Phenylalanine to norepinephrine is enhanced by co-factors vitamins B6 and C.

L-Phenylalanine300 mg
