Brian,
I'm sorry but I can't remember where I read this, but it was within the past two weeks. I get some newsletters from Dr. Weil and also the University of California At Berkley newsletter plus we have a dr.s column in the local newspaper that I read every day. I will try to do a follow up on this and find out the truth. Am going to a heart seminar by a cardiologist on Wednesday and you can be sure I will ask him that question. I am taking 500mg of the non-flushing niacin daily along with co-enzyme Q-10, B 6 and B 12 and also a multi vitamin and 1000mg of C. My cholesterol in 3 months went down about 20% so it has to be doing something.
I would really be interested in hearing from anyone out there who knows about flushing versus non-flushing niacin.
