Med Express is not high on my list of sites to use as reference, but I appreciate that you posted this.
Truly. Thanks!
You are wise. Niacinamide and nicotinamide are fake niacin. They were created for flush mitigation and extended release. The best route (and I believe better and much safer benefits) is plain ole nicotinic acid extracted from tobacco. One must learn to embrace the flush and use it as a gauge to evaluate one's niacin deficiency. I know of no other supplement that comes close to long term inflammation relief than niacin.
