More about this report

Clinical studies show that red yeast rice products can dramatically lower LDL ("bad") cholesterol. But our tests reveal that the amounts of cholesterol-lowering compounds in suggested daily servings can be as much as 500 times greater for one product than another, despite labels suggesting they provide the same amount of red yeast rice.

Which are the best red yeast rice supplements? We identified at least three that have the amounts and types of compounds shown to work in clinical trials. Unfortunately, we found many others that provide only small amounts of these compounds and seem unlikely to have any significant effect on cholesterol levels.  What's equally concerning, we discovered a potential toxin, citrinin in a well-known brand.

Several of the red yeast rice products we purchased for this review are the same ones tested in our last review but, as we discovered, now contain as much as 88% more, or 33% less, lovastatin (a natural cholesterol-lowerer) -- suggesting they may now be more, or less, effective than before.

Red yeast rice supplements don't list their amounts of lovastatin and related monacolins, so there's no way for you to know what's really in these supplements. tested them, providing you with invaluable, head-to-head comparisons.
