γ-Oryzanol is a mixture of lipids derived from rice (Oryza sativa).

[1] γ-Oryzanol occurs mainly in the fat fraction of rice bran and rice bran oil.

[3] γ-Oryzanol has been used in Japan for menopausal symptoms, mild anxiety, stomach upset, and high cholesterol.

[6] However, there is no meaningful evidence supporting its efficacy for these purposes.

[5] In the United States, it is sold as a sports supplement, but existing research does not support the belief that it has any ergogenic or testosterone-raising effects.
