Phenylethylamine (PEA)

nootropics

Phenylethylamine is an endogenous trace amine that functions as a neuromodulator, promoting dopamine and noradrenaline release in the brain. Often called the 'love chemical', it may enhance mood, motivation, and mental focus. However, it is rapidly metabolised by monoamine oxidase (MAO) enzymes, limiting its bioavailability and effectiveness as an oral supplement.

Research Summary

PEA is produced naturally in the brain and is associated with mood and pleasure, but oral supplementation has limited clinical evidence. Most human studies show minimal benefit due to rapid hepatic metabolism via MAO enzymes. Research remains preliminary, with more rigorous trials needed to establish efficacy and safety profiles.
