Vitamin B3, which is also known as niacin or nicotinamide, works in the body to maintain the nervous system, repair and rejuvenate the skin and boost energy levels from the food we eat.
Like a lot of other vitamins, the body cannot produce Vitamin B3 naturally, so we have to ensure we maintain a balanced diet that contains foods with Vitamin B3 in, such as beef, liver, poultry, eggs, fish, nuts, seeds and whole grains. Multivitamin supplements also contain Vitamin B3.
