Frequently Asked Questions


What is Oryzanol?

Oryzanol is a group of chemicals naturally found in rice and rice based products. It is found n the fat part of the rice grain. Apart from rice, Oryzanol is also prominently found in some fruits and vegetables. This chemical is not easily absorbed in the gut which reduces the absorption of cholesterol from the gut. This directly reduces the levels of LDL and increases HDL levels in the body.


What is positive impact of Oryzanol?

If you have abnormal cholesterol levels or dyslipidemia, taking gamma-oryzanol orally may help improve your lipid profile. Research suggests that it can potentially decrease total cholesterol, low-density lipoprotein (LDL or "bad") cholesterol, and triglycerides in individuals with high cholesterol. While there is interest in exploring other potential benefits of gamma-oryzanol, there is currently insufficient evidence to support its effectiveness for those purposes.


What is negative impact of Oryzanol?

When consumed orally, gamma-oryzanol is generally considered safe at doses up to 300 mg per day and is well-tolerated by most people. Additionally, when appropriately applied to the skin, gamma-oryzanol is also considered safe for use.


Who should avoid Oryzanol?

If you are pregnant or breastfeeding, it is advised to err on the side of caution and avoid the use of gamma-oryzanol, as there is insufficient reliable information regarding its safety during these periods. Furthermore, if you have a thyroid condition, gamma-oryzanol may potentially affect thyroid function. Therefore, it is recommended to consult with a healthcare provider before using gamma-oryzanol if you have a thyroid condition.


What are common sources of Oryzanol?

Oryzanol is primarily found in the fat fraction of rice bran and rice bran oil. Incorporating these sources into your diet can help you increase your intake of this beneficial nutrient. Other potential sources of oryzanol include wheat bran, as well as select fruits and vegetables.
