Phenylalanine
(found in Viva Vitamins PMA)
Phenylalanine is an essential amino acid. The body cannot manufacture it, so it must be obtained from food or supplement. It is a precursor to the neurotransmitter norepinephrine and the hormone CCK (cholecystokinin). CCK is the chemical message sent to the brain telling it you are full after eating. Norepinephrine is similar in that it also tends to reduce hunger; but
being an excitatory neurotransmitter it also helps to create positive feelings and a sense of mental energy or alertness. It is also needed by the thyroid gland and blood vessels. A form of phenylalanine, called the DL form, is a potent stimulator of endorphins, naturally produced chemicals in the body that stop the sensation of pain, and create a sense of well being. This form of phenylalanine has been used to allay chronic pain. Click Here to Read the Rest of this Article.
