DL-Phenylalanine Powder

  • Product Description

    What is DL Phenylalanine?

    DL Phenylalanine, also known as DLPA, contains different forms of the essential amino acid Phenylalanine. Phenylalanine is an essential amino acid, which means the body can only get it from external sources such as supplements or foods. Phenylalanine comes in three forms, L-Phenylalanine, D-Phenylalanine, and DL Phenylalanine. Phenylalanine is a precursor for tyrosine, dopamine, norepinephrine and epinephrine, and melanin. The “L” form is a natural substance normally found in protein rich foods such as meat, nuts, and dairy. L-Phenylalanine is also thought to be helpful in supporting mood. The “D” form of D-Phenylalanine is made synthetically and is believed to influence how the nervous system and brain interpret and respond to pain in the body. DL Phenylalanine may benefit mood issues as well as and physical discomforts and pain.

    DL Phenylalanine Effects and Research

    There is still research being conducted on DL Phenylalanine so the answer to the question, ‘what is DL Phenylalanine good for?’ can vary from person to person. Since DL Phenylalanine is an electrically neutral amino acid, it is able to cross the blood-brain barrier. Some believe that DL Phenylalanine for pain relief support works by blocking enkephalinase, an enzyme that breaks down enkephalins which are neurotransmitters for supporting pain management.

    A study conducted in Germany in 1978 found 60% of test subjects had a healthier emotional outlook after supplementing with DL Phenylalanine. 20% reported feelings of well being but to a lesser degree than the other subjects. DL Phenylalanine was found to bind to AMPA receptors in a study published in the Journal of Medicinal Chemistry. This binding to the AMPA receptors is said to increase the communication between brain synapses which may promote cognitive function. Studies have reported that DL Phenylalanine may elevate mood and may promote energy and support cognitive function. An open study reported that 30% of the tested subjects reported improved pain management support after using DL Phenylalanine daily for 2 weeks. DL Phenylalanine sleep benefits were shown in some small trials but further research is needed to verify these findings.


    As a dietary supplement, take 500mg of DL-Phenylalanine Powder once daily.
