Nootropic profile
Phenylethylamine (PEA)
A fast-acting trace amine neuromodulator that rapidly boosts dopamine and norepinephrine - produces an intense but short-lived burst of mood elevation, focus, and motivation often described as the "runner's high" molecule.

What is Phenylethylamine (PEA)?
Phenylethylamine (PEA, or beta-phenylethylamine) is a trace amine naturally produced in the human brain and found in foods such as chocolate, cheese, and red wine.

How to take it
- Standard dosage: 100-500 mg taken as needed for acute mood and focus boost
- Very short half-life: PEA is metabolised by MAO-B within 5-10 minutes. Effects are intense but brief (15-30 minutes) unless combined with an MAO-B inhibitor
- Combination strategy: Often paired with hordenine (a natural MAO-B inhibitor, 25-50 mg) to extend PEA's duration to 1-2 hours
- Timing: Take on an empty stomach for fastest onset. Effects are felt within minutes
- Not for daily use: Due to rapid tolerance development with frequent use, reserve for occasional cognitive boosts rather than daily supplementation
Watch out for
- Short duration limits risk: The rapid metabolism of PEA means its effects are self-limiting, reducing the risk of prolonged adverse effects
- Cardiovascular stimulation: Can increase heart rate and blood pressure acutely. Avoid in individuals with cardiovascular conditions or hypertension
- MAO inhibitor caution: Never combine PEA with prescription MAO inhibitors (MAOIs) - this combination can cause dangerous hypertensive crisis
- Migraine trigger: PEA is a known migraine trigger in susceptible individuals, particularly from dietary sources like aged cheese and chocolate
- Tolerance: Rapid tolerance develops with frequent use. Restrict to occasional use (2-3 times per week maximum)
The science, if you're curious.
- Activates trace amine-associated receptor 1, which modulates dopamine, norepinephrine, and serotonin release throughout the brain
- Triggers rapid vesicular release of dopamine, producing immediate mood elevation and motivation
- Stimulates norepinephrine release, enhancing alertness, attention, and arousal
- At higher concentrations, can reverse the direction of dopamine and norepinephrine transporters, flooding the synapse with catecholamines
Where to find it
- Capsules and powder: Available from nootropic and supplement retailers as pure PEA powder or capsules (100-500 mg)
- Dark chocolate: Contains small amounts of PEA, contributing to its mood-elevating reputation
- Combination products: Some nootropic stacks pair PEA with hordenine or other MAO-B inhibitors for extended effect
