taking 30 plls of Niacin would flush you hard out....I dont know if it would detox you,I bet you would feel like your on fire though.I used to take 1gram of niacin twice a day wile I was losing weight.....and that would make my skin feel all prickly.I do know the have flush free Niacin,But I dunno if you wanna ingest 30 pills....you may do more harm than good.
