You Help Make it Possible
As a crucial part of our mission, a portion of each purchase you make goes toward this fundraising effort. This is such a high priority that in some years our donations outpaced our profits. Thank you for helping support our efforts.
DL-Phenylalanine, or DLPA, is a 50/50 mixture of the D- and L- forms of the amino acid phenylalanine (phenylalanine is one of the few aminos that can be utilized in its D- form).

Researchers believe that D-phenylalanine (DPA) inhibits the action of an enzyme that breaks down endorphins and enkephalins. These are proteins that bind to opioid receptor sites in the brain, thereby influencing the perception of minor discomfort that is associated with normal physiological processes.

By obstructing the action of this enzyme, DPA may extend the life of endorphins and enkephalins and their positive influence on comfort levels. L-Phenylalanine is the precursor to two neurotransmitters that help support an alert state.*
