Roll Call does not check drug interactions or assess personal safety.
A naturally occurring trace amine found in the body and in foods like chocolate, structurally related to amphetamine-class stimulants but far weaker in effect.
Why it’s used
Taken by some for reported effects on mood or energy.
What the evidence says
Oral PEA is broken down very quickly by an enzyme in the gut and liver, and there is little clinical trial evidence in humans supporting mood or energy claims from oral supplementation. No NIH ODS fact sheet or major systematic review addresses it.

"Phenylethylamine"[Title/Abstract]
This says what this database holds under these terms. It is not a finding that no research exists.
Context
Its rapid breakdown after oral intake is a recurring point in the pharmacological literature and complicates interpreting any reported effects from supplement-level doses.
