Vitamin B3 (Niacin)
Vitamin B3 Niacin, also known as Niacin or Nicotinic Acid, is a water-soluble vitamin essential for energy metabolism and enzymatic reactions in the body. It plays a key role in the synthesis of coenzymes NAD and NADP, which are critical for cellular respiration and DNA repair. Niacin is widely used in pharmaceuticals, nutraceuticals, food fortification, and animal nutrition to prevent niacin deficiency and support overall health.
