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 them vary by more than 10-fold, despite labels suggesting they are all the sameSignificant amounts of these compounds are in some red yeast rice supplements, while others have hardly any; one product contained none.
 
Several of the red yeast rice products that we purchased for this review are the same ones tested for our last review but, as we discovered, now contain 29% to 88% less lovastatin (a natural cholesterol-lowerer) -- suggesting they may be less effective than before.

What's equally concerning is that a potential toxin, citrinin, was found in four products.
 
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. ConsumerLab.com tested them, providing you with invaluable, head-to-head comparisons. This is a must-see report for anyone using or interested in red yeast rice. Results of our last report were deemed so important to the medical community that they were published in the prestigious Annals of Internal Medicine. Our latest red yeast rice results may be even more important!
