Roll Call does not check drug interactions or assess personal safety.

A naturally occurring biogenic amine found in citrus peel and some plant extracts, chemically related to tyramine. It sometimes appears in supplements derived from bitter orange or citrus aurantium extracts.

Why it’s used

Included in some products marketed for energy or metabolism support, usually alongside other citrus-derived compounds like synephrine.

What the evidence says

There is very little human clinical research on N-methyltyramine specifically, whether as an isolated ingredient or at the doses found in supplements. Most available information comes from chemistry and food-science studies of citrus composition rather than trials on people.

This says what this database holds under these terms. It is not a finding that no research exists.

Context

No standard human dosing protocol has been established in published research; it is typically present as a minor constituent of a larger citrus extract rather than dosed on its own.

Insufficient dataToo little has been studied to say either way.
