In my research I've come across several studies that indicate that non-prescription niacin can lead to other problems. Any one else know anything about this?
I've also read that non-prescription Niacin actually causes less liver problems than Niaspan. I take 2000 mg of non-prescription time-relase Niacin every night before bedtime. There is flushing, but it is at tolerable levels and my doctor checks my liver functions regularly. Talk to your doctor (preferably an endocrinologist) about it.
