Gamma Oryzanol

How does Gamma Oryzanol 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.

Are there safety concerns?

Gamma oryzanol is POSSIBLY SAFE for most adults when taken by mouth or applied to the skin. However, the potential side effects of gamma oryzanol are not known.
