Side Effects of Red Yeast Rice

Question:
What are the side effects of red yeast rice?

Answer:
Red yeast rice supplements contain naturally-occurring statin compounds (or monacolins), such as lovastatin, that can help lower elevated cholesterol and triglyceride levels. Like prescription statin drugs, red yeast rice supplements can cause side effects such as altered liver enzymes, muscle pain, and digestive upset. However, studies suggest certain side effects may be less likely to occur or less severe with red yeast rice than with prescription statins, likely due to the natural combination of statins in red yeast rice as opposed to a single statin compound in prescription drugs. (Be aware that combining red yeast rice with prescription statin drugs increases the risk of side effects and should be avoided.)

It's important to keep in mind that ConsumerLab.com has found the amount of lovastatins in red yeast rice varies widely across products. Some also contain citrinin, a potential kidney toxin. This likely affects potency and the potential for side effects.

For two years, I used a red yeast rice brand which ConsumerLab.com's report showed to contain the highest amount of lovastatin. With just one pill per day, it kept my cholesterol lower (down to 205 from 260 before starting). I switched to a supermarket store brand because it was cheaper and my cholesterol jumped to 278 (taking 2 pills per day)! I don't think the store brand had anything in it -- is that possible? Can you test it? >>

In terms of white flour's negative effect on cholesterol - how about sourdough bread, does that count as not being white flour? What about brown pasta?

Best way to reduce cholesterol, is to reduce your intake of white flour, and added sugar. Try ti for 2 months--no white flour, no added sugars, and check your cholesterol level
