Why Your Body Needs Vitamin B3
Natural sources of vitamin B3: Vitamin B3, also known as niacin, plays a crucial role in converting the food you eat into energy. It supports over 400 enzymatic reactions in your body, aiding in DNA repair, cell signaling, and maintaining healthy skin and nerves. Niacin is water-soluble, meaning your body doesn’t store it, so you need to consume it regularly through your diet. HealthlineVerywell Health
