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.
L-phenylalanine releases cholecystokinin (Cck) and is associated with reduced food intake in humans: Evidence for a physiological role of cck in control of eating. People with phenylketonuria can have low levels of the amino acid tyrosine in their blood. Chronic pain improves with l-phenylalanine because it helps keep the body’s natural painkillers, endorphins, in the body longer. Deficiency of dihydropteridine reductase causes a substantial decrease in the rate of phenylalanine hydroxylation. Finally, the therapeutic use of particular amino acids in supplement form can often provide surprisingly quick and dramatic improvements in pain relief. Because few common mechanisms seem to relate the adverse effects of the different amino acids, they are discussed in alphabetical order. Nootropics depot offers 125g or 250g jars of high quality l phenylalanine powder. No randomized controlled trials have been done in the past 20 years to study any possible benefit of taking d-phenylalanine for chronic pain.

Instructions: As a dietary supplement, take 1 capsule, 1 to 3 times a day as needed, preferably between meals. Dl-phenylalanine (Dlpa) is an amino acid supplement, a synthetic phenylalanine. The l-isomer is used to biochemically form proteins, coded for by dna. Anyone with questions about whether l-phenylalanine is safe for them to take should consult with their medical practitioner. This is the result of the rapidly growing use of single amino acids as dietary supplements for enhancing health or performance as well as their use as flavoring agents. L-phenylalanine enables the production of mood-boosting neurotransmitters such as dopamine and norepinephrine. Blood and urine levels of phenylalanine tend to be lower in depressed patients than in healthy people. Foodpharmacy Blog and it’s editors do not advocate nutritional supplementation over proper medical advice or treatment and this sentiment will never be expressed through pages hosted under examine. How does l-phenylalanine work in the brain? Pregnant women with pku must control their blood phenylalanine levels even if the fetus is heterozygous for the defective gene because the fetus could be adversely affected due to hepatic immaturity. Thanks to these complex roles, l-phenylalanine may impact mental health, cognition, skin appearance, weight control, and more.
There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs. It is best not to take your phenylalanine supplement at the same time as a high-protein meal, as it may not be absorbed well. More research is needed to tell whether phenylalanine has any real effect on depression. We searched for trials which compared adding tyrosine to diet along with or instead of a phenylalanine-restricted diet. Two reviews of the scientific literature exist that mainly deal with effects in animals, and three major reports consider the safety of amino acids for human consumption. When the phenylalanine-restricted diet is no longer maintained, phenylalanine levels rise but may have less dramatic effects than seen during early infant and childhood development. In a study of 70 vitiligo patients, a combination of topical (10% Gel) and oral (100 Mg/kg daily) l-phenylalanine showed promising results. 4-Azido-l-phenylalanine is a protein-incorporated unnatural amino acid used as a tool for bioconjugation in the field of chemical biology. Or in your case you may want to try a supplement.
However, in patients with breast cancer, the rates of protein synthesis in the tumor and expression of tumor proliferation marker ki67 were enhanced after 3 d of arginine (30 G/d) supplements. Therefore, the placenta converts excess phenylalanine to tyrosine for the developing fetus. Taking l-phenylalanine with certain antidepressants, called maois (Monoamine oxidase inhibitors) causes similar reactions, reports the university of maryland medical center. On the other hand, a rare metabolic disorder called phenylketonuria (Pku) occurs in people who are missing an enzyme that the body needs to use phenylalanine. L-tyrosine is an amino acid found in the diet that is metabolized to produce catecholamines such as dopamine and adrenaline. L-phenylalanine can help boost cognition especially in stressful situations. This suggests that supplemental tyrosine should be avoided by pregnant women and infants. What is the scientific evidence for phenylalanine? All these conditions can influence how you react to supplemental phenylalanine.
L-phenylalanine works best on an empty stomach. Instead, you have to get phenylalanine from supplements and dietary sources. A diet based on a single plant item will not be adequate, but we no longer worry about pairing proteins (Such as beans with rice) at a single meal. Consult your doctor, practitioner, and/or pharmacist for any health problem and before using any supplements or before making any changes in prescribed medications. Levodopa: A few case reports suggest that phenylalanine may reduce the effectiveness of levodopa (Sinemet), a medication used to treat parkinson disease. 18 The casr is expressed on hormone-secreting enteroendocrine cells, leading to suggestions that it may sense amino acids within the gi tract to modulate gut hormone release. Many l-phenylalanine benefits are tied to how it potentiates the creation of several important neurotransmitters. If undergoing medical therapies, then consult with your respective therapist or health care professional about possible interactions between your treatment, any pharmaceuticals or drugs being given, and possible nutritional supplements or practices hosted on examine. L-phenylalanine helps the brain produce important chemicals called neurotransmitters. It is used in the manufacture of food and drink products and sold as a nutritional supplement for it’s reputed analgesic and antidepressant effects. People with pku must eat a diet that avoids phenylalanine and take tyrosine supplements for optimal brain development and growth.
Source Naturals L-Phenylalanine
Because l-phenylalanine is an essential amino acid, it is not synthesized in the human body and must be supplied by dietary intake or supplementation. Free-form amino acids can be readily absorbed and utilized by the body and provide the precursors for all other amino acids made by the body. What is dl-phenylalanine (Dlpa) and how does it work? As a dietary supplement, take 500mg of l-phenylalanine once daily. Individuals with the amino acid metabolism disorder phenylketonuria (Pku) are unable to process phenylalanine properly. Purebulk’s supplements are tested by accredited third party labs in the usa to ensure their identity, purity and potency. 21 In addition, specific l-amino acids, including l-phe, stimulate the release of the energy and glucose homeostasis-regulating gut hormones peptide yy (Pyy), glucagon-like peptide 1 (Glp-1) and gastric inhibitory polypeptide from isolated rat small intestine through a casr-dependent mechanism. However, it may be best for pregnant women to avoid taking phenylalanine supplements. Multiple reports, including the ummc studies, show that low phenylalanine levels cause confusion, reduced alertness, depression, memory problems, low energy, slow metabolism, appetite disturbances, edema, liver damage, muscle loss, skin lesions, weakness and slowed growth in children. Clinical research reported by vitasouth shows l-phenylalanine suppresses appetite, helps people burn fat, and maintains muscle while they follow a moderate workout program.
One of these, a synthetic amino acid called d-phenylalanine (Dpa), decreases pain by blocking the enzymes that break down endorphins and enkephalins, the body’s natural pain-killing chemicals.

Canine gut receptors mediating pancreatic responses to luminal l-amino acids. Several animal studies and some research involving humans suggest that a synthetic version of the natural amino acid phenylalanine called d-phenylalaline (Dpa), reduces pain by decreasing the enzyme that breaks down endorphins. The l-form is found in foods and used to produce proteins in your body, while the d-form can be synthesized for use in certain medical applications (2, 3). L-phenylalanine (Lpa) is converted into the amino acid l-tyrosine in your liver. That causes high levels of phenylalanine to build up. L-phenylalanine can be a highly effective nootropic for boosting cognitive function because it boosts norepinephrine and dopamine production. L-phenylalanine selectively depresses currents at glutamatergic excitatory synapses. L-phenylalanine is converted into l-tyrosine which in turn is converted into l-dopa in the brain.
This suggest that phenylalanine may help to imbue feelings of joy and wellbeing, and support a more positive state of mind. Phenylalanine is an amino acid that builds proteins, neurotransmitters, and other crucial molecules in your body.
