Red yeast rice is a dietary supplement with a statin-like component observed to reduce blood cholesterol levels, although not nearly to the same extent as statin drugs.  Consumer Lab tests show at least half not to contain what they say they do.

Now, on top of that, the supplements were associated with kidney disease (at least 50 cases) and deaths (at least 2) among takers in Japan.

Comment: Dietary supplements are the wild west of the food supply.  Anyone can make and sell them.  Because they are mainly harmless, nobody much bothers to test them, even major pharmaceutical companies.  Problems with red yeast rice supplements have been known for a long time.  As a result, supplements are risky.  How risky?  Nobody knows.  I don’t recommend them.
