Regular Retail: $16.00D-phenylalanine is reported to inhibit the metabolism of opiate-like substances called enkephalins in the brain, which makes it a useful nutrient for supporting a healthy response to inflammation and discomfort.
L- phenylalanine is known for its ability to help suppress appetite and elevate mood.
L- phenylalanine can be converted to L-tyrosine (another amino acid) and subsequently to L-dopa, norepinephrine and epinephrine, neurotransmitters important to proper brain function.
Additionally, L- phenylalanine can also be converted (through a separate pathway) to phenylalanine, a substance that occurs naturally in the brain and appears to elevate mood. Warning: Individuals with PKU (phenylketnuria) or who are pregnant or nursing should not use this product.
