Hello Anon
Thank you for writing.
Red yeast rice is a traditional Chinese substance made by fermenting a type of yeast called Monascus purpureus over rice. Various formulations of this product have been used in China since at least 800 AD as a food and also as a medicinal substance within the context of Traditional Chinese Herbal medicine . This ancient preparation contains naturally occurring substances similar (and, in some cases, identical) to cholesterol-lowering prescription drugs in the “statin” family.
Red yeast rice is thought to be effective for lowering cholesterol, presumably because of its statin constituents. There is evidence to support this use.
In clinical trials, use of red yeast rice has not been associated with any significant side effects. However, red yeast rice contains naturally occurring statin drugs, and use of statin drugs can cause side effects ranging from minor to life-threatening. Some of the most common include muscle pain, joint pain, liver inflammation, and peripheral nerve damage; severe breakdown of muscle tissue (rhabdomyolysis) leading to kidney failure has also occurred. It is almost certain that red yeast rice can cause the same problems if it is used by enough people, and there are at least two case reports in the literature of muscle injury caused by red yeast rice; in one case, rhabdomyolosis developed. Due to the relative lack of regulation of supplement manufacture, the statin content of red yeast rice products is unpredictable, and this could increase potential risk. In addition, red yeast rice may at times contain the toxic substance citrinin.
Based on the known effects of statins, pregnant or nursing women, women likely to become pregnant, young children, and people with liver or kidney disease should not use red yeast rice. Furthermore, red yeast rice should not be combined with fibrate drugs , cyclosporine , erythromycin-family drugs, antifungal drugs, or high-dose niacin.
So Anon - yes, your pain could certainly be due to taking this red yeast rice. The only way to know is to stop taking it and see how you feel in a few weeks.
