Your body also uses it to maintain healthy skin and to aid the function of your nervous and digestive systems. Poor diet and other factors can lead to an increased need for this vitamin.

Your body converts Niacin into Niacinamide before it can use it. Make sure your body gets all the energy you need from your food with Nature's Way Niacinamide.
