GAMMA ORYZANOL Overview Information

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 and symptoms of menopause and aging.

Some people use it for increasing testosterone and human growth hormone levels, as well as improving strength during resistance exercise training.

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.

GAMMA ORYZANOL Uses & Effectiveness What is this?

Possibly Effective for:

  • Lowering cholesterol levels. Gamma oryzanol seems to significantly decrease total cholesterol, “bad” low-density lipoprotein (LDL) cholesterol, and triglyceride levels. But its effects on “good” high-density lipoprotein (HDL) cholesterol levels are less clear. Various research studies have returned differing results.

Insufficient Evidence for:

  • Increasing testosterone and human growth hormone levels.
  • Improving strength during resistance exercise training.
  • Treating symptoms of menopause and aging.
  • Other conditions.
More evidence is needed to rate the effectiveness of gamma oryzanol for these uses.
