Has anyone ever heard of or tried taking the vitamin Niacin for a couple days before a UA? A friend told me that Niacin, a vitamin that boosts metabolism, can generally speed up the process of getting your system clean. It was recommended to me to quit smoking about a week prior to the UA and take 2 to 4 Niacin pills a day and it works to pass a UA. Never needed to try it but just curious if it had worked for anyone else.
