Gamma oryzanol is a mixture of ferulic acid esters of plant sterols and triterpene alcohols. It is primarily extracted from rice bran oil, which is rich in antioxidants and phytochemicals. Historically, gamma oryzanol has been popular in Japan and other Asian countries for its health benefits, including its purported ability to lower cholesterol and alleviate menopausal symptoms.
Gamma Oryzanol for High Cholesterol
How Gamma Oryzanol Reduces Cholesterol
One of the primary reasons gamma oryzanol is used is its potential to reduce cholesterol levels. The compound works by inhibiting the absorption of cholesterol from foods in the intestines. This action helps lower total cholesterol and “bad” low-density lipoprotein (LDL) cholesterol levels, as well as triglycerides, which are harmful blood fats.
Research Insights
Studies have shown mixed results regarding gamma oryzanol’s effect on cholesterol. Some research indicates that oral intake of gamma oryzanol can effectively lower total cholesterol, LDL cholesterol, and triglycerides. However, its impact on “good” high-density lipoprotein (HDL) cholesterol remains inconsistent. In some cases, HDL cholesterol levels increase, while in others, they remain unchanged.
Practical Application
Incorporating gamma oryzanol into a diet can be achieved through rice bran oil, which naturally contains this compound. Regular consumption of rice bran oil has been linked to lower LDL cholesterol levels, supporting the findings related to gamma oryzanol supplementation.
Gamma Oryzanol for Menopause Symptoms
Managing Menopause Symptoms
Gamma oryzanol is often promoted for managing menopause symptoms. The compound’s potential benefits are believed to stem from its effects on luteinizing hormone (LH). During menopause, fluctuations in LH levels can lead to symptoms like hot flashes and mood swings. Researchers speculate that gamma oryzanol may help regulate LH levels, thereby alleviating these symptoms.
The Science Behind the Claims
While anecdotal evidence and preliminary research suggest that gamma oryzanol may help with menopause symptoms, robust scientific studies are lacking. The precise mechanism by which gamma oryzanol might influence LH levels and reduce menopause symptoms is not fully understood, necessitating further research.
Safety and Considerations
General Safety
Gamma oryzanol is generally considered safe for most people when used appropriately. However, it’s important to be aware of potential side effects and interactions with other medications.
Impact on Thyroid Function
One critical consideration is that gamma oryzanol may lower thyroid function. Therefore, individuals with thyroid problems should avoid using this compound. Always consult with a healthcare professional before starting any new supplement, especially if you have underlying health conditions or are taking other medications.
Animal Studies and Ethical Concerns
While we do not support animal testing, it’s worth noting that animal studies suggest gamma oryzanol might reduce testosterone production. The implications of this finding for human health are still unclear and require more research.
