Background
Rice bran comes from the outer layer of rice (Oryza sativa). Rice bran oil is popular as a "healthy oil" in Japan, Asia, and particularly India.
Rice bran oil contains substances that might decrease how much cholesterol the body absorbs. Rice bran might also decrease calcium absorption, which might help prevent certain types of kidney stones from forming.
People use rice bran for high cholesterol, diabetes, high blood pressure, athletic performance, and many other purposes, but there is no good scientific evidence to support many of these uses.
Don't confuse rice bran with rice bran arabinoxylan compound, or other forms of bran such as oat bran and wheat bran.

When applied to the skin: There isn't enough reliable information to know if rice bran is safe or what the side effects might be.
Children: Rice bran is possibly safe when used appropriately. It has been used in food for infants for up to 6 months with no side effects.
Gastrointestinal (GI) conditions: Don't use rice bran if you have a digestive tract problem such as ulcers or other stomach disorders. The fiber in rice bran could block your digestive tract.

Effectiveness
NatMed Pro rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
Possibly effective Effectiveness definitions
- Abnormal levels of cholesterol or blood fats (dyslipidemia). Taking rice bran or rice bran oil by mouth daily seems to somewhat reduce low-density lipoprotein (LDL or "bad") cholesterol. It's not clear if it affects other types of cholesterol.
Possibly ineffective Effectiveness definitions
- Colon cancer, rectal cancer. Eating dietary fiber, such as rice bran, doesn't seem to reduce the risk of colon or rectal cancer.
