Rice Bran Oil is one of nature best-kept secrets. It is primary extracted from the germ (inner husk) of the rice grain, where as the bran (outer layer of the grain) is used for medicinal purposes. This natural oil, which is expeller pressed, has the presence of natural antioxidants making it an excellent ingredient for food grade products.
Rice Bran Oil is rich in antioxidants, such as Vitamin E, ferulic acid, linoleic acid, oleic acid, palmitic acid, and oryzanol. The oil acts as both a carrier and emollient. In Japan, Rice Bran Oil is used as a skin and hair beauty enhancer. It is also used throughout the world in a variety of cosmetics, especially for those that treat dry and mature skin.
Benefits of Rice Bran Oil
- High in antioxidants to fight free radicals and aid in slowing down the effects of aging.

- The small molecule enable it to penetrate into the skin without being greasy.
Other benefits include:
Rice bran oil contains significant levels of both gamma and delta tocotrienols (approximately 500 ppm), a forms of Vitamin E, that have been found to be able to accumulate in cancer cells and kill the tumours. In a study conducted at Kyushu University in Japan, researchers looked at the effects of tocotrienols on mouse cancer cells. There was a significant delay in growth in the cancer cells. “Our results suggested that accumulation is critical for the anti-tumour activity of tocotrienols,” said Japanese lead researcher, Yuhei Hiura, reporting in “The Journal of Nutritional Biochemistry.”
Originating in the Japanese culture, skin care with rice bran oil is becoming more popular. To this day, one of the highest compliments a Japanese woman can receive is to be called a “nuka bijin” which means “a rice bran beauty.” Having smooth healthy skin is due to the oryzanol in the rice bran oil that whitens the skin slightly. As the skin is exposed to sunlight, the rice bran oil reacts as a sunscreen protecting the skin from harmful ultraviolet rays. The oryzanol impedes melanin pigmentation by restraining the erythema activity of tyrosinase as it stops the ultraviolet rays’ transmission at the skin’s surface. The use of rice bran oil in sunscreen products and hair conditioners is on the increase in the United States and Japan.
Rice bran oil contains three healthy antioxidants useful in protecting the body’s cells against the effects of free radicals–tocopherol, tocotrienol and oryzanol. In addition, rice bran oil does not require hydrogenation for stability and has a high percentage of fatty acids (oleic, 46 percent; linoleic, 36 percent; and linolenic, 1 percent). Antioxidant companies have switched their basic oil to rice bran oil. This movement is an indication that industry leaders recognize rice bran oil’s lipid oxidative stability. Lipid oxidative stability is important in the prevention of pathologic processes such as cardiovascular diseases, arthritis and inflammatory processes.
Rice bran oil contains gamma oryzanol, a group of ferulate esters of triterpene alcohols and phytosterols that have been linked to many health benefits. Gamma oryzanol is effective in reducing plasma cholesterol and reducing cholesterol absorption, decreasing early atherosclerosis. In addition, gamma oryzanol inhibits platelet aggregation that could lead to blood clots. Rice bran oil contains tocotrienol (a form of Vitamin E) which has been found to inhibit the activity of HMG-CoA reductase, an enzyme that synthesizes cholesterol, a major factor in heart disease. In a study conducted at the University of Rochester, Mohammad Minhajuddin, Ph.D., and researchers determined that the tocotrienol in rice bran oil reduced cholesterol in rats up to 42 percent while lowering LDL cholesterol up to 62 percent.
Mick Vann of the Austin Chronicle wrote, “The more I discovered, however, the better this oil sounded. Web searches revealed dozens of scientific research articles claiming all manners of health benefits: It reduces bad-cholesterol levels, boosts good cholesterol, and fights free radicals; it’s an anti-inflammatory, reverses liver damage, inhibits cancer growth, reduces effects of menopause, and on and on”
