Niacin comes in a couple forms. The only one that causes flushing is the nicotinic acid form. This is the one that is most effective lowering cholesterol.
If you take that form, BE CAREFUL!
I ran out and drove to the health food store to get more. After I got back in the car, I took 1/2 a tab (abt 250 mg).
Dropped my blood pressure so fast I almost passed out, good thing I wasn’t driving yet!
I use an extended release form that you can get over the counter from Endurance Products. Found it as a result of a book I read by Robert Kowalski. I had no flushing and it has kept my cholesterol in check without the side effects I was having from a statin. Worth checking out for anyone on this board who needs some cholesterol reduction but is having trouble with a statin. I’m NOT a shill! Just someone with a genetic predisposition towards high cholesterol who ran into trouble with statins and ended up getting a reduction from the very, very old school niacin. Your mileage may vary.
