What is niancin?

Niacin, also known as vitamin B3, is a water-soluble vitamin that plays a crucial role in energy metabolism and the maintenance of healthy skin, nerves, and digestive systems. It exists in two forms: nicotinic acid and nicotinamide (niacinamide). Niacin can be obtained from dietary sources such as meat, fish, nuts, and whole grains, and it is also available as a dietary supplement.
