What is Red Yeast Rice?
Red Yeast Rice is used both as a fermented food as well as a supplement extract. It contains several active molecules, including the drug Lovastatin, which decreases cholesterol production by the liver. Red Yeast Rice can be brewed into sake, vinegar, wine, and food pickling or used simply for its red color (R).
When Red Yeast Rice containing Lovastatin was tested on thousands of patients who had previously had a heart attack it was well-tolerated and decreased new heart problems, old heart problems and mortality (R).
In the United States, Red Yeast Rice should not contain lovastatin, so it may not have the same benefits and risks.
Goats fed with Red Yeast Rice produce less methane since the related gut microorganism is inhibited (R).
Red Yeast Rice on average contains 73.4% starch, 0.8% fiber 5.8% protein by weight (R). A standard dose of 2 g/day includes 8 mg of Lovastatin. Taking this with even 250 mL of grapefruit juice will be like taking 5 times the dose (R).
The FDA regulates lovastatin, so commercial Red Yeast Rice in America should not contain lovastatin itself (R, R). If it does contain statins they are at around 0.4% and should not be taken by pregnant women (R).
Health Benefits Of Red Yeast Rice
1. Red Yeast Rice Treats High Cholesterol
2. Red Yeast Rice Improves Heart Function
In patients who had suffered a heart attack, long-term therapy with Red Yeast Rice lowered mortality, cut the risk of a future heart attack in half (from 10.5% to 5.7%) and lowered LDL, lowered triglycerides, and raised HDL. It was safe and well tolerated in 5000 humans (DB-RCT) (R).
General scientific consensus says Red Yeast Rice improves blood vessel flexibility and lowers blood vessel stiffness in 40 moderately high cholesterol humans (DB-RCT) (R).
3. Red Yeast Rice Fights Cancer
4. Red Yeast Rice Improves Metabolic Syndrome
5. Red Yeast Rice Treats Obesity
6. Red Yeast Rice Reduces Inflammation
7. Red Yeast Rice Improves Bone Growth
Red Yeast Rice Combinations
- Lowers TNF-α, IL-6, and IL-2 (R, R) and muscle Coenzyme Q10 (R).
- Lowers hsCRP, improving the function of blood vessels, and combating lipids (R).
- Lowers HSD3B2, AKR1C3, and SRD5A1 (R).
- Lovastatin is broken down by CYP3A4 (R).
Grapefruit juice interacts with CYP3A4 (breaks down statins) and the statins can get to dangerously high levels (R).
The type of Red Yeast Rice determines the number of statins, but often 2.4 g of Red Yeast Rice contains 10 mg of statins (R).
