Overview

Gamma oryzanol is a substance that is taken out of rice bran oil. It is also found in wheat bran and some fruits and vegetables. People use it as medicine.

Gamma oryzanol is used for high cholesterol, symptoms of menopause, and many other conditions, but there is no good scientific evidence to support most of these uses.

How does it work ?

Gamma oryzanol might reduce cholesterol levels by reducing absorption of cholesterol from foods.

Gamma oryzanol is also often promoted for treating menopause, but it is unclear how it would work for this use. Some researchers suspect it might be helpful due to effects on luteinizing hormone (LH). However, this effect has not been shown in people.

Some people use gamma oryzanol for increasing testosterone and growth hormone levels. However, gamma oryzanol appears to have no effect on these hormone levels. In fact, animal studies suggest that gamma oryzanol might even reduce testosterone production.
