Introduction: Adult individuals in Indonesia showed changes in diet and lack of physical activity, therefore increasing the risk of hypercholesterolemia and obesity. One of nutritional therapy for hypercholesterolemia is rice bran oil, which contains active substances that works synergistically in controlling lipid profile. The substances are gamma-orzanol, phytosterols, and vitamin E isomers (tocotrienol and tocopherol). Methods: A clinical trial was conducted for 4 weeks in City Hall of Jakarta on 20 males, age 1955 years old, with mild-moderate hypercholesterolemia, to assess lipid profile improvement of the supplementation of rice bran oil 45 ml/days compared to 15 ml/days without changing eating patterns. Results: After 4 weeks of intervention, there was significant difference in total cholesterol level between both groups (p = 0.049). In the group that received 45 ml/days of rice bran oil, total cholesterol level decreased 14%, and in the group of 15 ml/days total cholesterol level decreased 7.8%. The reduction of LDL and triglycerides and the increase of HDL were not significantly different between both groups (p >0,05). There was no significant changes of body weight in both groups. Conclusion: This study showed that consumption of 45 ml/days rice bran oil led to better improvements in lipid profiles compare to 15 ml/days. It has been demonstrated that gamma oryzanol and plant sterols in rice bran oil have the capability to remove cholesterol from bile salt micelles, thus decreasing cholesterol absorption in intestine.
