Source Naturals L-Phenylalanine, an essential amino acid, is a precursor of the amino acid tyrosine and a whole series of neurotransmitters and hormones. Source Naturals L-Phenylalanine is first converted to tyrosine, which becomes L-dopa, which converts to norepinephrine, a key neurotransmitter and an adrenal hormone. Source Naturals L-Phenylalanine is also a direct precursor of PEA (Phenylethylamine), another important neurotransmitter. Cognition / Nerves The human brain is the most complex structure known to man; much of how it functions and enables us to think, feel, contemplate abstract concepts, plan our future, and control many bodily processes is yet to be discovered. The function of the brain and nervous system is based on the unique structure of nerve cells (also called neurons), which take in and send out messages in the form of electrical impulses running through the phospholipids and minerals of the cell membranes. Although it is only two percent of our body weight, the brain consumes 20 percent of our energy. Neurotransmitters, brain chemicals that pass messages from one neuron to another, must be produced in adequate quantities to support mood, intelligence, concentration, assertiveness and calmness. This creates a tremendous need for nutritional fuel and energy. Brain functioning can be significantly improved by the right quantity and quality of nutrients. Suggested Use 1 to 2 tablets daily.
