Not quite the same effect you’d get from something like Adderall but with a side benefit of more sociability. The result is nearly instantaneous improvements in cognitive performance, attention, awareness, pleasure, libido, and a sense of well-being. PEA instead only increase the amount of neurotransmitters that get released when a neuron is stimulated by receiving an impulse from a neighboring neuron.
- Investigators at Alcon Research identified 5-HT2A receptors in ocular tissue and demonstrated that topical administration of R(-)DOI, a potent 5-HT2 receptor agonist identified by us, produced a significant decrease in IOP in cynomolgus monkeys.
- In addition, at least 5 deaths have been reported in people who had taken “legal” phenethylamine-based drugs 64.
- Its ability to influence our mood, motivation, and cognitive performance underscores the delicate balance of chemicals that govern our mental states.
- Nonetheless, PEA continues to be a popular ingredient in nutritional products, valued for its natural origin and potential to support mood and cognitive function in a safe and accessible manner for most healthy adults.
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.

Phenylethylamine ADHD
Though contested, evidence suggests that it can pass the blood brain barrier after injection into the body, where it gets to work. Because of the similarity to various amphetamines, Phenylethylamine is believed to have a pronounced stimulating effect on the body. Even still, experts are divided on whether or not the chemical remains in the body long enough after supplementation to have any real effect on the brain, which is as of yet unknown.
- No clinical evidence supports the use of phenethylamine for any of the conditions listed in this section.
- Moreover, PEA has been shown to interact directly with dopamine receptors, potentially enhancing the sensitivity of these receptors to dopamine.
- In one study, 14 patients suffering from severe depression consume up to 60 mg a each day Phenylethylamine (PEA) together with the dosage of 10 mg selegiline (L-Deprenyl) for up to 50 weeks.
- One study found that supplementing with 10–60 milligrams of phenethylamine daily along with the antidepressant drug called selegiline (Anipryl, Eldepryl) helped relieve depression in 60 percent of participants.
- Another food that contains PEA is chocolate, where it is not produced by bacteria, but during the thermal processing of cocoa (Granvogl et al., 2006).
Best Herb For ADHD: Natural Ingredients That May Support Focus, Calm, And Cognitive Health
Chocolate is considered one of the best dietary sources, and levels increase in cocoa beans when they are fermented and roasted. However, studies have found that eating chocolate doesn’t lead to an increase in PEA levels in the nervous system, since it is metabolized rapidly before reaching the brain. Research tells us that people who have low levels of this chemical may be prone to experiencing depression, poor attention span and other psychiatric conditions. Phenylethylamines are a group of phenethylamine derivatives which contain PEA as a backbone. These derivative compounds are formed by replacing one or more hydrogen atoms in the core structure.
Despite the authors’ efforts to decrease intrinsic clearance by lipophilicity reduction, no correlation was found, although several 5-HT2 potent compounds were synthesized. Nichols et al. 200 explored the impact of methoxy and bromo scanning along the benzyl ring of 25I-NBOMe (139). Ortho or meta positions enhanced activity, whereas the para substitution reduced it. One of the best derivatives was 140, which was compared with its tryptamine congener 141, less potent overall in the 5-HT2 assays performed (Figure 17c). Another class of GPCR targeted by 2-phenethylamines are constituted by α-adrenergic receptors (or α-adrenoceptors). There are two main groups of α-adrenergic receptors, α1 and α2, with several subtypes within (α1A, α1B, α1D, α2A, α2B, α2C).
One study found that just 60 mg of phenylethylamine paired with selegiline reduced depression in several patients over the course of one year (x, x, x, x, x). 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. Once in the brain, PEA interacts with various neurotransmitter systems, particularly those involving monoamines like dopamine, norepinephrine, and serotonin. Its relationship with these neurotransmitters is complex and multifaceted, often acting as a neuromodulator that enhances or prolongs their effects.

Structures of S(+)amphetamine S(+)AMPH, S(+)methamphetamine S(+)METH, and their phenylpropanolamine counterparts. 5-HT2 receptor agonists 26, 27, 29–31, 40, 41, and the 5-HT2 receptor antagonist M (28). Carbonic anhydrases (CAs) are Zn-based (also Fe-based) metalloenzymes present across all living organisms of the different life kingdoms. Received 2022 Dec 22; Revised 2023 Jan 10; Accepted 2023 Jan 11; Collection date 2023 Jan. In addition to the cognitive benefits, Noopept is also supposed to provide a psychostimulatory effect (it makes you feel happy). The primary reason most people supplement is to achieve the supposed mood boost.
5-HT6 Receptor Ligands
This seemed to be borne out by subsequent stimulus generalization studies. Beta-phenylethylamine (β-PEA) is a well-known and widespread endogenous neuroactive trace amine found throughout the central nervous system in humans. In this study, we demonstrated the effects of β-PEA on psychomotor, rewarding, and reinforcing behaviors and affective state using the open-field test, conditioned place preference (CPP), self-administration, and ultrasonic vocalizations (USVs) paradigms. We also investigated the role of the dopamine (DA) D1 receptor in the behavioral effects of β-PEA in rodents. Using enzyme-linked immunosorbent assay (ELISA) and Western immunoblotting, we also determined the DA concentration and the DA-related protein levels in the dorsal striatum of mice administered with acute β-PEA. The results showed that acute β-PEA increased stereotypic behaviors such as circling and head-twitching responses in mice.

While small amounts of PEA are found in some foods, taking PEA supplements is the best way to increase levels. Even so, some experts think that supplementing may not have significant effects, due to how this compound is rapidly broken down into inactive components. There’s evidence that phenylethylamine may have similar effects as natural endorphins and serve as a possible factor in the antidepressant actions of exercise.
Phenethylamine
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.
Side Effects Of PEA
Phenethylamine is produced in tiny amounts throughout the brain and spinal cord and is made from the essential amino acid phenylalanine, which is mainly found in protein-rich foods 3. The increase in synaptic concentrations of dopamine is achieved through blocking directly the transporter of dopamine. This is the way that drugs such as the methylphenidate help to increase dopamine levels. A study conducted in 2008 revealed that PEA affects serotonin transporters through interactions with receptors for TAAR.
The supplement is available in salt, powder and tablet form for easy dosing and consumption. Since the chemical is short-lived, opting for a slow release is typically the best way to prolong the effects (x, x). A phenylethylamine HCL supplement stimulates chemicals in the brain that produce extra energy and focus.
Chapter II summarizes the impact of PEA on three psychological disorders, attention deficit hyperactivity disorder, depression, and schizophrenia. PEA has also been found in the brains of humans and other mammals (Paterson et al., 1990; Philips et al., 1978), which is facilitated by its high solubility in plasma and its ability to cross the blood-brain barrier (Oldendorf, 1971). Like its α-methylated derivative, amphetamine, PEA has stimulant effects which lead to the release of so called biogenic amines, including dopamine and serotonin (Bailey et al., 1987; Rothman & Baumann, 2006).
