How It Works

In addition to rice starch, protein, fiber, sterols, and fatty acids, red yeast rice contains numerous active constituents, including monacolin K, dihydromonacolin, and monacolin I to VI.

Researchers have determined that one of the ingredients in red yeast rice, called monacolin K, inhibits the production of cholesterol by stopping the action of a key enzyme in the liver (e.g., HMG-CoA reductase) that is responsible for manufacturing cholesterol.15 The drug lovastatin (Mevacor ) acts in a similar fashion to this red yeast rice ingredient. However, the amount per volume of monacolin K in red yeast rice is small (0.2% per 5 mg) when compared to the 20-40 mg of lovastatin available as a prescription drug.16 This has prompted researchers to suggest that red yeast rice may have other ingredients, such as sterols, that might also contribute to lowering cholesterol.

Along with its evaluation in animal trials,17 red yeast rice has been clinically investigated as a therapy for reducing cholesterol in two human trials. In one trial, both men and women taking 1.2 grams (approximately 13.5 mg total monacolins) of a concentrated red yeast rice extract per day for two months had significant decreases in serum cholesterol levels.18 In addition, people taking red yeast rice had a significant increase in HDL ("good") cholesterol and a decrease in LDL ("bad") cholesterol. Elevated triglycerides were also found to be lowered.

A double-blind trial at the UCLA School of Medicine determined that red yeast rice in the amount of 2.4 grams per day (approximately 10 mg total monacolins) in capsules significantly decreased total- and LDL-cholesterol levels in a sample of people with elevated cholesterol after 12 weeks of therapy. Triglycerides were also reduced in those taking red yeast rice. However, unlike the original study, HDL values did not increase substantially.19

How to Use It

The red yeast rice used in various studies was a proprietary product called Cholestin , which contains ten different monacolins. The amount of Cholestin used in these studies was 1.2-2.4 grams (5-10 mg of monacolins) per day in divided amounts for 8-12 weeks.20, 21

Note: Cholestin has been banned in the United States, as a result of a lawsuit alleging patent infringement.

Other red yeast rice products currently on the market differ from Cholestin in their chemical makeup. None contain the full complement of ten monacolin compounds that are present in Cholestin, and some contain a potentially toxic fermentation product called citrinin.22 Despite these concerns, other red yeast rice products are being widely used and anecdotal reports suggest that they have a similar safety and efficacy profile as that of Cholestin.
