    Product Overview


    • Dietary Supplement
    • DL-Phenylalanine
    • Supports an Alert State

    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 amino acids 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 discomfort. 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.

    Suggested Use

    1 to 3 tablets daily.

    Other Ingredients

    Dibasic calcium phosphate, stearic acid, sorbitol, magnesium stearate, colloidal silicon dioxide and modified cellulose gum.

    I have an depression and often I dont have any surplus or energy, but these pills helps me to get surplus to do stuff and they help me to get through my day. They have help me very much to get through my bad days and depression. I have it so much better after i started to take them but I only take them if I dont have any surplus or if I have a very bad day.

    Thanks for your feedback!

    Good energy and mood booster

    Posted by iHerb Customer on Mar 09, 2017 | Verified Purchase

    I found that 750 mg of DLPA gave a mild mood and energy lift, although with a bit of irritability. I might try half a tablet next time.

    Thanks for your feedback!
