In addition, phenethylamine injected intravenously in rats was absorbed mainly by the lungs, liver, and kidneys, and less than 1% reached the brain 55. The phenethylamine in chocolate may, in theory, explain its reputation as an aphrodisiac (a substance that increases libido) 50. Phenethylamine can be used to indicate food quality and freshness since large amounts of phenethylamine are produced by bacteria 47. Below is a summary of the existing animal and cell-based research, which should guide further investigational efforts. However, the studies listed below should not be interpreted as supportive of any health benefit.
General Health Goals And Effects
As such, it is believed to play a role in depression and other psychiatric conditions. The current view is that supplementing with this compound could boost your attitude or have a highly stimulating effect. Since elevated levels of amines are usually an indicator of food spoilage, it is possible use detection of amines as an indicator of food freshness. One such techniques is thin-layer chromatography to separate and identify amounts of tyramine and PEA (Garcia-Moruno et al., 2005).

Do not take this or any other supplement if under the age of 18, pregnant or nursing a baby, or if you have any known or suspected medical conditions and/or taking prescription drug(s) or OTC medication(s). Always consult with a qualified health physician before taking any new dietary supplement. Have reported severe hyperthermia following the use of these substances.13 Studies in animals have suggested that some metabolites may be exposed to increased toxicity from 4-MTA.

The Chemistry And Biology Of Phenylethylamine
An impressive 86 percent experienced relief from depression symptoms for up to 50 weeks. PEA has been shown (mostly in animal studies) to activate dopamine transporters and certain chloride channels that affect moods and behaviors. Pharmaceutical drugs that are substituted phenethylamines include phenelzine, phenformin, and fanetizole, among many others. Phenylethylamine supplements can be purchased from health food stores and online retailers.
Serotonin And Dopamine: Understanding The Key Differences And Roles
- These combinations are also explored for their role in neuroprotection and stress adaptation.
- Stimulus generalization was demonstrated to be time-dependent, with the phenolic compounds having a longer onset of action time (decreased ability of the agents to penetrate the BBB?).
- For instance, products like bliss mood support are designed to sustain a positive mental state, while energy support cordyceps mushroom and lions mane medicinal mushrooms enhance physical and mental vitality through their known adaptogenic properties.
- Ω-nitrostyrene is added to the previously prepared lithium aluminum hydride in ether while stirring.
- Open-chain, flexible alicyclic amine derivatives of this motif are enumerated in key therapeutic targets, listing medicinal chemistry hits and appealing screening compounds.
The concept of the blood–brain barrier (BBB) was proposed as early as 1900 by Lewandowsky14 (reviewed15) but was not fully appreciated for many decades to come. This means that most polar agents (i.e., those that are not very lipophilic – simple phenols, catechols, carboxylic acids, quaternary amines) typically fail (or display a reduced ability) to gain entry to the brain. Other agents, those possessing unprotected primary amines, such as PEA (1) or tryptamine – agents of moderate lipophilicity – if they penetrate the BBB, are rapidly metabolized by enzymes such as monoamine oxidase (MAO). As a consequence, polar agents usually possess minimal, if any, central activity. The exploration of phenylethylamine (PEA) and its potential impact on human cognitive health presents several fascinating directions for future research. As this compound continues to gain attention for its association with enhanced mental clarity, mood support, and energy regulation, further investigation could illuminate the mechanisms through which PEA interacts with the central nervous system.
14 Opioid Receptors
However, many TAAR1 ligands including PEA (1), tryptamine, and 4-hydroxyamphetamine, have minimal central activity when administered by typical systemic routes of administration. Why are certain phenyl/arylalkylamines, such as these, centrally inactive, or nearly so, when administered systemically? One reason might be that they are unable to readily cross the blood–brain barrier.
- Chocolate is the richest natural source of theobromine, but coffee and tea contain some of it too.
- As such, researchers advocate for more study into the long-term effects if for nothing else than safety’s sake.
- Many of these psychoactive compounds exert their pharmacological effects primarily by modulating monoamine neurotransmitter systems; however, there is no mechanism of action or biological target that is common to all members of this subclass.
- Tejler et al. 172 described the synthesis of lactose derivatives, such as 121 with the phenethylamine moiety by 1,3-dipolar cycloadditions, with selective galectin-1 inhibition (Figure 14).
Our data show that βPEA increases extracellular dopamine both in DAT-1 transfected cells and cultures of differentiated neurons. RTI-55, a cocaine homologue and DAT inhibitor, completely blocked the βPEA-induced effect in transfected cells. However in neuronal cultures, RTI-55 only partly inhibited the increase of extracellular DA generated by βPEA. These results suggest that βPEA requires DAT-1 and other, not yet identified proteins, to increase extracellular DA when tested in a native system. Furthermore, our results suggest that βPEA-induced increase of extracellular DA does not require functional monoamine vesicles as genetic ablation of the C.
In another study, 9 out of 10 depressed patients that previously did not respond to conventional antidepressant treatments reported elevated mood after taking a combination of phenethylamine and selegiline. The sample size of this study prevents us from drawing any conclusions 17. Both the yolks and whites of eggs also contain the amino acid, according to a study.
The Chemistry Of Chocolate
Because PEA is chiral, it has two mirror-image forms (enantiomers) that function pharmacologically in different ways. The S-enantiomer of PEA is naturally found in foods and the human body, but the R-enantiomer is synthesized in a lab for research. Activation of TAAR1 receptors inhibit the uptake and induces the release of dopamine, norepinephrine, and serotonin.
Current scientific research highlights its potential benefits when supplemented alongside ingredients like theanine or reishi mushroom blends. For those seeking a boost in vitality, combining PEA with NAD boosters, kanna nasal spray, or even theanine nasal spray for GABA activation could be effective. Furthermore, energy support from cordyceps mushrooms and cognitive enhancements from lion’s mane medicinal mushrooms amplify PEA’s complementary effects on mental sharpness. Mushroom cocoa blends, especially those incorporating lion’s mane and cordyceps, pair well with PEA to fortify both mood and focus. In the present study, we demonstrated the psychoactive properties of β-PEA and their underlying mechanisms using multiple behavioral and emotional state assessments in rodents. The results showed that acute β-PEA administration significantly increased circling and head-twitching behaviors and produced drug-paired place preference in mice.
For instance, some studies have found lower levels of PEA in individuals with depression, leading to speculation about its potential therapeutic role in mood disorders. Similarly, altered PEA levels have been observed in conditions such as attention deficit hyperactivity disorder (ADHD) and Parkinson’s disease, suggesting a possible link between PEA metabolism and these neurological conditions. Interestingly, PEA has also been studied for its potential effects on appetite and weight management. Some research suggests that PEA may help suppress appetite and increase metabolic rate, although more studies are needed to fully understand these effects. This potential impact on weight management has led to interest in PEA as a natural supplement for supporting healthy body composition.
Drugs Made From Phenethylamine
In fact, changes in urinary βPEA levels have been documented in various human disorders including schizophrenia, attention deficit hyperactive disorder (ADHD) and depression (Baker et al. 1991, O’Reilly and Davis 1994, Sandler et al. 1980). Moreover, in vivo studies showed that physiological βPEA concentrations directly and transiently inhibit the firing rate of the DA neurons through the activation of the DA D2 autoreceptors (Ishida et al. 2005, Mercuri et al. 1997, Rodriguez and Barroso 1995). Interestingly, the firing inhibition caused by βPEA as well as βPEA-induced behaviors (Barroso and Rodriguez 1996) were not affected by pretreatment with the vesicular monoamine transporter (VMAT) blocker reserpine. These data suggested that βPEA stimulates the release of DA from a non-vesicular cytoplasmic pool. In this study, we investigated the effect of βPEA on extracellular levels of DA in C.
These ingredients not only elevate mood but also support resilience against stress. As dopamine is a precursor to the brain’s reward circuitry, PEA’s role in amplifying these pathways contributes to its reputation for promoting both immediate and long-lasting mood enhancement. Ultimately, while phenethylamine may hold promise as a nootropic, it is important to weigh the benefits against potential risks and side effects.
This results in an alcoholate precipitate, which thickens the solution requiring more ether to be added. Finally, using acid hydrolysis the metal alcoholate is decomposed and the product can be isolated and extracted from the ether. Patients undergoing surgery should stop taking phenylethylamine supplements at least two weeks prior to the operation because it impacts the central nervous system and may interfere with the procedure (x). The role of PEA in various neurological and psychiatric conditions has been a subject of growing interest in the scientific community. Research has shown that PEA levels may be altered in certain conditions, potentially contributing to or reflecting underlying neurochemical imbalances. Among the various neurotransmitters influenced by PEA, dopamine stands out as particularly significant.
This might cause serious side effects including heart problems, shivering, and anxiety. Taking phenethylamine along with meperidine (Demerol) might cause too much serotonin in the brain and serious side effects including heart problems, shivering, and anxiety. PEA may interact with other drugs, especially those that modify the brain’s levels of monoamine neurotransmitters. Taking PEA along with these medications should be avoided as it may raise the possibility of negative consequences. It comprises a carbon-carbon single bond holding a phenyl group (C6H5) to an ethylamine group (CH3CH2NH2). This structure is responsible for its psychoactive properties and its ability to interact with neurotransmitter systems in the brain.
