Niacin, also known as vitamin B3, plays a crucial role in energy metabolism by aiding in the conversion of carbohydrates, fats, and proteins into usable energy. It is essential for the synthesis of NAD and NADP, two coenzymes that are vital for cellular respiration and various biochemical reactions. Additionally, niacin contributes to skin health, digestive system function, and the maintenance of healthy nerves. A deficiency in niacin can lead to pellagra, characterized by symptoms such as dermatitis, diarrhea, and dementia.
