Got it like in a couple o fdays, and took two tablets, and got that flushing. I did some research and that flushing lets you know it's working. The studies have been done on the flushing kind, not the (non-flushing) kind. That flushing gets blood and all sorts of blood components to where it needs to be.THIS PRODUCT ACTUALLY REDUCES AND FLUSHES OUT PLAQUE FROM CORONARY AND HEART ARTERIES. NOTHING ELSE DOES THAT EXCEPT SURGERY. NIACIN IN COMBINATION WITH RED YEAST RICE OR EVEN NIACIN ALONE CAN BE USED IN PLACE OF LIPITOR AND ALL THOSE OTHER STATINS. THEY HAVE HELD CHOLESTEROL DOWN JUST THE SAME AND DOCTORS KNOW IT TOO.
