D, L-Phenylalanine, 500 mg, 100 Vegetarian Capsules

Gluten FreeNon GMO LE CertifiedEnhances MoodDietary SupplementPhenylalanine is an essential amino acid that can be converted to L-tyrosine in the liver. Tyrosine is used in the nervous system to make a class of neurotransmitters called catecholamines: dopamine, norepinephrine and epinephrine. Epinephrine, made from tyrosine in the adrenal medulla, functions as a neurohormone and is known as adrenaline.In addition to acting as a neurotransmitter that supports healthy mood and sleep, norepinephrine is now known to protect brain cells by promoting a healthy inflammatory response, inhibiting oxidative stress and supporting healthy neuronal growth and connectivity.Dopamine, though long associated with more primal aspects of brain function linking behaviors to rewards, is recognized now as a mediator of higher-order cognitive capacities.The diminishment in brain catecholamine production that occurs with aging may be a contributing factor in normal age-related cognitive decline. Providing catecholamine precursors can help support healthy cognitive function. The enzyme that catalyzes the conversion of tyrosine to dopamine may work more efficiently if its co-factors (vitamins B6 and C) are included.Phenylalanine supplementation supports healthy neurotransmitter synthesis and clinical trials suggest it may promote positive moods.Since both norepinephrine and epinephrine can cause smooth muscle (arterial) contraction, care with blood pressure should be taken when supplementing with phenylalanine.D,L-phenylalanine is a 50/50 mixture of its two stereoisomers.

D-Phenylalanine, 500 mg, 60 Veggie Caps

Science-Based Nutrition™Helps Support Healthy MoodDietary SupplementVeganNon-GMO / Gluten Free / Soy FreeDoctor's Best D-phenylalanine is a non-protein amino acid that acts as an inhibiting agent to enzymes that degrade enkephalins, naturally occurring peptides in the body that metabolize endorphins. Endorphins are neurotransmitters that play a key role in the function of the nervous system and are associated with feelings of pleasure. By limiting production of enzymes that brake down endorphins, the supplement can help support a healthy mood and normal functioning of the nervous system. & nbsp;Helps support healthy moodHelps support endorphin metabolismHelp support neurotransmitter function

DLPA, 750 mg, 60 Tablets

Dietary SupplementDL-PhenylalanineSupports an Alert StateDL-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.

DLPA, 375 mg, 120 Tablets

Dietary SupplementDL-PhenylalanineSupports An Alert StateDL-Phenylalanine, or DLPA, May support healthy levels of endorphins and enkephalins, compounds naturally produced by the body that have a positive effect on comfort levels. & nbsp;Research suggests that DLPA helps regulate the enzyme action the body uses to break these compounds down, which may extend their use by the body. L-Phenylalanine is also a precursor to the mood-related neurotransmitter dopamine. & nbsp;

L-Phenylalanine, 250 mg, 100 Tablets

500 mgDietary SupplementFree FormAn Essential Amino AcidSuitable For Vegetarians & nbsp;L-Phenylalanine, an essential amino acid, is a precursor of the amino acid tyrosine and a whole series of neurotransmitters and hormones. Phenylalanine is first converted to tyrosine, which becomes L-dopa, which converts to norepinephrine, a key neurotransmitter and an adrenal hormone. L-Phenylalanine is also a direct precursor of PEA (phenylethylamine), another important neurotransmitter.
