However, the levels of PEA in these foods are relatively low, and it’s unlikely that consuming them will have a significant impact on mood or happiness. While there is some evidence to suggest that PEA may be able to aid in weight loss, it’s important to note that there is no magic pill or supplement that can instantly lead to significant weight loss. If you are looking to lose weight, it’s important to adopt a healthy and balanced diet, engage in regular physical activity, and consult with a healthcare professional to determine the best approach for your individual needs. The changes in DA concentration of the dorsal striatum after the acute administration of saline or β-PEA were measured using a DA ELISA kit (#KA1887, Abnova, Taipei, Taiwan). According to the manual, standards, controls, and samples (protein lysates of the dorsal striatum) were subjected to extraction and acylation assays.

The solubilized protein samples were stored in a deep freezer before use. Monoamine oxidases (MAO) are flavin-containing enzymes that catalyze the oxidative deamination of monoamines, which are bound to the outer membrane of mitochondria. Common MAO substrates are 5-hydroxy-tryptamine and catecholamines (dopamine, norepinephrine and epinephrine). MAO A and MAO B are the two enzyme isoforms, sharing a 70% sequence identity and differentiating each other in the substrate scope 213.

The sustained antidepressant effect of Phenylethylamine (PEA) may be an alternative to SSRIs. If you’re ADHD or ADD, you should see an improvement in mood, attention span, focus and mental clarity. Not quite the same effect you’d get from something like Adderall but with a side benefit of more sociability.
It is likely because the monoamine oxidase levels are higher than dopamine as older you become. Furthermore, using PEA particularly with a MAOI aids in restoring dopamine and other neurotransmitters which are commonly diminished as you age. PEA can be quickly degraded by monoamine oxidase B (MAO) so unless you combine PEA with an MAO inhibitor do not expect its effects to last for long. The majority of people experience peak energy within 15 minutes, and then lasting energy for 30 minutes. Phenylethylamine is a type of drug which releases dopamine in your brain. This food can be used to create this drug in small amounts but the effects only last for 10 minutes.
These patients should refrain from this supplement, unless a medical professional prescribes them. Phenylethylamine HCL is a stimulant that can cause harsh, unwanted side effects. For those looking to give their workouts an extra boost or get an extra edge on their weight loss efforts, PEA supplements can be a reliable option.
9 Dopamine Transporter (DAT)
Phenylethylamine (PEA) The recommended dosage for cognitive benefits is 500 mg, up to 3 times per day. Neurohackers recommend using the MAOI (inhibitor) supplement 15 minutes prior to the PEA dose. Phenylethylamine is a natural chemical that is responsible for pleasurable feelings. It is also responsible for the “love drug” effect that people experience when they are in love with someone. Phenylethylamine improves brain health and function in a variety of ways. This category comprised of PEA substances includes amphetamines, stimulants, empathogens, psychoactives, appetite suppressants, nasal decongestants, bronchodilators and antidepressants.
- No clinical evidence supports the use of phenethylamine for any of the conditions listed in this section.
- Β-phenylethylamine (βPEA) is an endogenous trace amine present in the central nervous system, however, its role in the mammalian physiology is still unknown.
- 1-(3,4-Dimethoxyphenyl)-2-aminopropane (3,4-DMA; 46) (Figure 9) can be viewed as a “ring opened” analog of MDA (42), and PMA (44) and MMA (47) represent compound 46 minus one of the two methoxy groups.
- I do feel it for about 30 minutes, especially if I take a break for a day or two.
- In treating patients dealing with depression after a romantic breakup, Leibowitz found that a class of antidepressants called monoamine oxidase (MAO) inhibitors helped them.
- Then, structural alteration of the amphetamine structure leads to a host of other actions.
BD-1047 (Figure 22) is an open-chain, flexible 2-phenethylamine acting as antagonist of σ1R 244. Opioid receptors are a class of GPCR proteins consisting of three receptor types, mainly µ-, δ-, and κ- types, with a variety of functional roles in the nervous system, such as pain signaling, growth, respiration, and immunological response 223,224. Relevant side effects are well known, such as constipation or drug dependence/abuse. Jensen et al. developed 25CN-NBOH (135) (Figure 17a) as a result of halide substitution by the cyano moiety, displaying high-picomolar/low-nanomolar binding affinities (competition binding assays with 3Hketanserin) and functional potencies at 5-HT2A receptor. Leth-Petersen et al. 199 designed a library of 25B-NBOMe analogues 136, such as 137 or 138 in the search of decreasing intrinsic clearance (Figure 17b).
The Chemistry And Biology Of Phenylethylamine
All drug solutions were prepared immediately prior to the beginning of each experiment. This review represents a concise, central summary of relevant 2-phenethylamine-based leads and research hits, which spans receptors and their corresponding therapeutic indications. All described compounds, targets and activities were retrieved using “2-phenethylamine” as title or keyword term in the chemical databases SciFinder 247 and Scopus 248. Additionally, a SciFinder and Scopus structure search, with the scope described early in this review (Figure 2), was employed. Peroxisome proliferator-activated (PPAR) receptors are peroxisome receptors and subcellular organelles performing several tasks related to cholesterol and fatty acid metabolism. Several agents have been developed in relation to PPAR to address obesity, inflammation or neurodegenerative disorders (Figure 21, Table 8) 233,234.
Cohen and Wittenaur25 examined this in detail and concluded that both 5-HT and tryptamine contracted rat fundus by acting on the same population of 5-HT receptors, but via receptors that were distinct from brain 5-HT1 or 5-HT2 receptors. This caused us to seriously question the relationships we had identified between peripheral fundus 5-HT receptor affinity and human hallucinogenic action or central DOM-like stimulus activity. Phenylethylamine, also known as PEA, is a naturally occurring compound that is found in various foods and living organisms. It belongs to a group of compounds called monoamines, which play a role in regulating mood, appetite, and other bodily functions. Food training and catheter implantation surgery were performed as described previously 48. The timeline for self-administration procedures is illustrated in Figure 4A.
Phenylethylamine Clinical Research
This has led to speculation that PEA supplementation could potentially help manage ADHD symptoms, although more research is needed to confirm this. Studies have shown that PEA can enhance focus, alertness, and mental energy. This effect on mental performance is one reason why PEA has garnered interest in the field of nootropics, substances that enhance cognitive function.
Supplements Containing Phenylethylamine
At the same time, it’s important to approach PEA supplementation with caution and responsibility. While it offers promising benefits, it’s not a magic bullet, and its use should be considered in the context of overall health and wellness strategies. As we conclude our exploration of phenylethylamine, it’s clear that this remarkable molecule plays a crucial role in our brain’s complex neurochemistry, particularly in its regulation of dopamine. From its mood-enhancing properties to its potential cognitive benefits, PEA stands out as a fascinating subject in the realm of neuroscience and mental health. Another significant aspect of PEA’s psychological effects is its role in motivation and reward systems. By enhancing dopamine activity, PEA may contribute to increased motivation, goal-directed behavior, and the experience of reward.
- Additionally, in addition to their prominent therapeutic applications, it is worth mentioning the recreational use of a long list of alkaloids incorporating the aforementioned moiety (“designer drugs”) 2, responsible for drug abuse-related conditions 3,4,5,6,7,8.
- One study in schizophrenic patients found lower amounts of phenethylamine and its metabolite, phenylacetic acid, in cerebrospinal fluid (CFS) 20.
- Other substituted phenethylamines, like amphetamines, can also alter behavior and may cause hallucinations 57.
- Your brain naturally converts L Phenylalanine into Phenylethylamine (PEA).
- This result suggests that in native neurons DAT-1 and other unknown proteins are required by βPEA to elevate extracellular DA.
As we wrap up our journey through the fascinating world of phenylethylamine, it’s clear that this “love chemical” is much more than just a fleeting feeling of romance. From its role in mood regulation to its potential cognitive benefits and therapeutic applications, PEA continues to captivate researchers and health enthusiasts alike. While generally considered safe, high doses of PEA can potentially cause side effects like headaches, anxiety, or insomnia. As with any supplement, it’s important to consult with a healthcare provider before starting PEA supplementation, especially if you have any pre-existing health conditions or are taking medications. Results of stimulus generalization studies using rats trained to discriminate either MDMA (1.5 mg/kg) or PMMA (1.25 mg/kg) from saline vehicle in a 2-lever procedure.
Among the various neurotransmitters influenced by PEA, dopamine stands out as particularly significant. Dopamine plays a crucial role in our brain’s reward and pleasure centers, influencing everything from motivation and learning to motor control and emotional responses. The relationship between PEA and dopamine is so intertwined that understanding one inevitably leads to insights about the other. One of the key features that make PEA such a potent neuromodulator is its ability to cross the blood-brain barrier. This protective barrier, which separates the brain’s blood vessels from the brain tissue itself, is notoriously selective about which substances it allows to pass through.
Just prior to the discovery of multiple subtypes of brain 5-HT receptors (see below), it was found that 3Htryptamine labeled a population of rat brain receptors distinct from any 5-HT receptor types then known (see Grandy3 for a review). This provided one of the first opportunities for us to examine the binding of centrally-acting arylalkylamines at brain receptors rather than at peripheral fundus 5-HT receptors. We,7 and others,3 showed that certain phenylalkylamines, including PEA (1), amphetamine, and 4-chloroamphetamine displayed low μM affinity for 3Htryptamine-labeled sites in rat brain frontal cortex homogenates. While PEA is naturally produced in the body, it can also be synthesized in a laboratory and used as a supplement.
Medications For Depression (MAOIs) Interacts With PHENETHYLAMINE (PEA)
Specifically, bacteria from the families Enterobacteriaceae and Pseudomonadaceae can produce cadaverine and putrescine in spoiled turkey meat. It was suggested to use tyramine, putrescine, and cadaverin to quantify meat freshness (Fraqueza et al., 2012). In vegetables, high levels of tyramine were only seen in brine, unless the vegetables were contaminated prior to processing or the temperature and storage time were extreme (Moret et al., 2005). While phenethylamine supplements are thought to be relatively safe for humans, high doses of phenethylamine supplements have been shown to cause death in mice 68. Note that taking phenethylamine supplements is different from taking substituted phenethylamines, which should be taken with extreme caution as they have been shown to cause schizophrenia-like psychosis 21, 65.
