Overview Information

Rice bran arabinoxylan compound is an extract of arabinoxylan from rice bran. It is used as a medicine.

Rice bran arabinoxylan compound is most commonly used for boosting the immune system. It is also used for cancer, reducing side effects of cancer treatment, chronic fatigue syndrome (CFS), hepatitis C, and other conditions, but there is no good scientific evidence to support these uses.

How does it work?

Rice bran arabinoxylan compound might work by improving the body's natural immune system.


Uses & Effectiveness?

Insufficient Evidence for

  • Chronic fatigue syndrome (CFS). Early research suggested that rice bran arabinoxylan compound might improve symptoms and immune function in people with CFS. But more recent evidence shows that rice bran arabinoxylan compound does not improve symptoms of CFS including fatigue. All of the studies to date have been small and/or low quality, so more high quality research is needed.
  • Swelling (inflammation) of the liver caused by the hepatitis C virus (hepatitis C). Early research suggests that taking rice bran arabinoxylan compound helps to clear hepatitis C virus from the bloodstream in people with a certain type of hepatitis C. It seems to work as well as pegylated interferon plus ribavirin.
  • Liver cancer. Early research shows that taking rice bran arabinoxylan compound in combination with standard therapy might help people with liver cancer live longer compared to standard therapy alone. It might also help prevent liver cancer from returning after treatment.
  • Boosting immune function.
  • Diabetes.
  • Preventing and treating cancer.
  • Other conditions.
More evidence is needed to rate the effectiveness of rice bran arabinoxylan compound for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: Rice bran arabinoxylan compound is POSSIBLY SAFE when taken by mouth short-term. Rice bran arabinoxylan compound has been used safely in doses of 1 gram daily for 12 months or up to 6 grams daily for 2-3 months. There isn't enough reliable information to know whether rice bran arabinoxylan compound is safe to take for a longer period of time.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Not enough is known about the use of rice bran arabinoxylan compound during pregnancy and breast-feeding. Stay on the safe side and avoid use.

"Auto-immune diseases" such as multiple sclerosis (MS), lupus (systemic lupus erythematosus, SLE), rheumatoid arthritis (RA), or other conditions: Rice bran arabinoxylan compound might cause the immune system to become more active. This might increase the symptoms of auto-immune diseases. If you have one of these conditions, it's best to avoid using rice bran arabinoxylan compound.
