Which vitamin is also referred to as niacin?

Niacin is a water-soluble vitamin that is part of the vitamin B complex group, specifically known as vitamin B3. It plays a crucial role in various bodily functions, including energy metabolism, DNA repair, and the production of certain hormones. Niacin is vital for the conversion of nutrients into energy and helps maintain the health of the skin, digestive system, and nervous system.

The vitamin B complex includes several other vitamins, such as B1 (thiamine), B6 (pyridoxine), and B7 (biotin), each with distinct functions and health benefits. However, niacin specifically refers to vitamin B3, distinguishing it from the other B vitamins in terms of both its chemical structure and its biological roles.
