Red Yeast Rice was recommended by my acupuncturist at first, for high cholesterol. I had tried all the other natural products recommended in books & various health care practitioners (garlic, co-q 10, niacin, fiber, etc.), as well as being practically a vegetarian (just a little fish & chicken), eating very little butter, eggs and cheese. But my levels kept creeping up, topping out at 258 about 3 months ago. After 2 months of Red Yeast Rice, it went down to 219! Now, I enjoy butter, cheese... whatever I want.
