Roll Call does not check drug interactions or assess personal safety.
A mixture of plant compounds (ferulic acid esters of sterols) extracted from rice bran oil.
Why it’s used
Taken by some, historically in bodybuilding circles, in the belief it may influence growth hormone or testosterone levels or support muscle strength.
What the evidence is for
claims regarding anabolic hormone response and strength gains.
What the evidence says
A controlled trial in resistance-trained men found no significant effect of gamma oryzanol combined with ferulic acid on strength gains or anabolic/catabolic hormone responses compared with placebo. Overall human evidence for the muscle-building and hormonal claims made for gamma oryzanol is weak, though some research on cholesterol and menopausal symptoms exists separately.
Context
The cited strength-training trial used gamma oryzanol alongside ferulic acid over a period of resistance training; it did not isolate gamma oryzanol alone.
