Source Naturals DL-Phenylalanine, or DLPA, is a 50/50 blend of the D- and L- forms of the amino acid phenylalanine (phenylalanine is one of the few amino acids that can be utilized in its D- form). Researchers believe D-phenylalanine (DPA) inhibits the action of an enzyme that breaks down endorphins and enkephalins. These are proteins which bind to opiate receptor sites in the brain. 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.

Customer Ratings & Reviews

Rated 4.5 out of 5 by 2 reviewers.
Rated 5 out of 5 by Great to learn I was doing research and trying to find different vitamins and products that help you overall. This was one that really keeps you alert, focused, and is really important. It's great that Swanson Vitamins has a glossary where you can read about, learn and appreciate how useful certain products can be for your mind and body. Thank you Swanson for bringing an overall well-being. February 5, 2015
Rated 4 out of 5 by Helpful supplement DLPA is one of my regular supplements, wouldn't be without it. Although the pill size of this one is larger than Swanson's 500mg one, this one delivers 750mg. I think I benefit from this higher dosage. September 9, 2013
