| Basics |
|
Gamma oryzanol is a compound made up of a plant sterol (a fat-like substance) and ferulic acid. Since gamma oryzanol is a non-essential nutrient, there is no deficiency level associated with it. However, its addition to the diet does appear beneficial to athletes and others who are physically active.

| Usage Directions |
|
Supplement doses for gamma oryzanol range from 100-500 mg per day. Absorption is poor (less than 10%) but can be improved if emulsified. Much of the human research with gamma oryzanol uses 300 mg per day. Healthy people do not appear to need this supplement.

| Sources |
|
Rice bran oil is the principal source of gamma oryzanol, but it is also found in the bran of wheat and other grains, as well as various fruits, vegetables, and herbs. However, to get enough gamma oryzanol to reach recommended therapeutic dosages, supplements are needed.
