yeah ur statistics you are getting are highly over-thought! Niacin is completely harmless, it causes miner skin redness and burning, thats it, i have used it for over a year now! 500 mg pills i take one a day, its comnpletely harmless. Another thing if niacin was that harmful they would not use a large portion of it in energy drinks such as red-bull 100% niacin. The only thing niacin has done to me is help me sucessfully pass drug tests, and has yet to fail me.
