Does Niacin really boost your metabolism a lot? Or just a little bit to give you energy?

Niacin does boost metabolism, but not too much. The reason niacin does that is because it's a thermogenic (dietary supplements used to stimulate the body's burning of fat). Niacin raises your body temperature in order to boost your metabolism.
