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

A compound found naturally in barley and some other plants, chemically related to tyramine. It appears in some "fat burner" and pre-workout supplement formulas.

Why it’s used

Taken for purported stimulant or metabolism-supporting effects.

What the evidence says

Hordenine has been studied mainly in animal and laboratory (in vitro) research. There is essentially no published human clinical trial data on oral hordenine supplementation, so claims about fat loss or stimulant effects in people are not backed by direct human evidence.
