Will niacin cause body odor,not the type from not bathing?

i`ve noticed a body odor and i shower every day.i`ve tried differant soap.it get`s in my clothes too

Niacin purifies your toxins in your body.... so anything that is a toxin is going to be released I've noticed the same thing. Well you could add softener to clothes to keep them smelling good and where Cologne to cover up the odor. Drink lots of water to dilute the smell as well.
