It does do a good job of ridding your body of all toxins and giving you a clear UA. I would look for the kind that does not have the flushing effects otherwise it will make your skin crawl when you start to flush. It feels like your skin is on fire so make sure it is the none flushing kind. It will still work, just not give you the heebie jeebie's. Next time don't smoke pot withing a couple of weeks to a month if you want a clear UA. Good Luck!
Niacin.does work but not the flush free one .. Cant say flush free on the bottle . I got my boyfriend the flush free and tested him and came back positive still .Then i realized it said flush free .so i went got the other one .(which is hard to find)that just said niacin 500mg. And they have one 250 ..so we did that one for 5 days and he tested clean..3×a day he took it .
