    Red Yeast Rice Supplements

    Good read. Buy bodybuilding supplements only from those you trust.

    Red Yeast Rice Supplements May Contain Dangerous Surprises
    A new study reveals that you might not be able to trust the amount of cholesterol-lowering compound in each pill

    If you're seeking to lower your high cholesterol with red yeast rice, you may not be getting what you expect from the supplement, a new study finds.

    Researchers bought 28 different brands of the popular pills from major retail chains and tested these red yeast rice supplements for monacolin K, the cholesterol-lowering compound found in red yeast rice that's chemically identical to the prescription cholesterol drug lovastatin (Mevacor and generic).

    Two of the tested brands contained no monacolin K at all, while the potency in others ranged from almost negligible amounts to concentrations higher than the amount of lovastatin found in some prescription pills.

    But nothing on the labels of the different supplements provided information about the critical differences within each bottle, and most did not warn about the potential risks of taking red yeast rice pills for people already taking prescription statins to lower cholesterol.

    The study, published today in the European Journal of Preventive Cardiology, was financed in part by a grant from Consumers Union, the policy and mobilization arm of Consumer Reports.

    The label on a bottle of red yeast rice supplement tells you how much red yeast rice is in each pill—600mg, for example. What it doesn't indicate is how much monacolin K each pill contains, since those concentrations vary, according to the new study. That means "there’s no correlation between what’s listed on the label and how it will affect your body," says lead author Pieter Cohen, M.D., an associate professor of medicine at Harvard Medical School who studies dietary-supplement safety.

    These findings point to larger issues with supplements, where stronger federal protections are needed, says Chuck Bell, programs director for Consumers Union. “We wouldn’t allow a prescription drug with this level of variability on the market,” says Bell.
    Dangers of Red Yeast Rice Supplements

    Red yeast rice (shown at top) is made by fermenting ordinary rice with a fungus that is reddish in color. As with the varying levels of alcohol found in different beers, the specifics of the fermentation process can yield very different levels of monacolin K.

    But the Food and Drug Administration has suggested that there are limits to the amount of monacolin K it will allow in a red yeast rice supplement. In 2014, for example, it sent a warning letter to a company whose red yeast rice product had 4 mg of monacolin K in a daily dose, noting that this "is almost half of the lowest recommended daily dose of lovastatin." These pills, the FDA determined, qualified as an “unapproved drug,” not a supplement.

    In the new study, 21 percent of the tested supplements had levels of monacolin K that were even higher. Two of the tested brands had daily doses that were greater than 10 mg.

    Earlier research has raised questions about the unpredictable content of red yeast rice supplements. But in 2010, the FDA implemented a set of manufacturing guidelines designed to “give consumers greater confidence that the dietary supplement they use has been manufactured to ensure its identity, purity, strength, and composition.”

    What the new study shows, Cohen argues, is that the new rules are inadequate. They are meant to ensure that red yeast rice is indeed present in a red yeast rice supplement, but they don't regulate its potency or overall content, he says.

    And according to the National Center for Complementary and Integrative Health, it’s not just the concentration of monacolin K that’s in question: Some red yeast rice supplements also contain a toxin called citrinin, which has been linked to kidney failure.
    What You Need to Know

    If you’re already taking a red yeast rice supplement, make sure your doctor knows. Or if you’re thinking about trying one, talk to your doctor before you start. A low-cost prescription statin might be a better choice, says Cohen, since your doctor can carefully control the dosage so you know exactly what you're taking.

    “Red yeast rice can cause exactly the same side effects as statins, and those include muscle, liver, and kidney problems,” says Marvin M. Lipman, M.D., Consumer Reports' chief medical adviser. “And, even more important, they aren’t standardized, so there’s no way to know the quantity or quality of the ingredients.”

    The upshot? “Taking these pills is not a good idea,” Lipman says.
