What does niacin do for the body?

Answer 1

Niacin is a water soluable vitamin. It helps the body by converting the calories from foods (carbs, proteins and fat) into energy. It helps you maintain healthy skin and helps the functioning of the digestive system, in addition to encouraging a healthy appetite.

High doses can lower bad cholesterol and triglycerides while raising good cholesterol. However, never take high doses unless instructed to do so by your doctor.

Any of the vitamin that your body does not need or doesn't use gets flushed out of your body via urination.
