Vitamin B3 is important for making two essential coenzymes: NAD and NADP. These coenzymes help with redox reactions. These reactions are crucial for making ATP, the energy source for cells.

Niacin helps break down fats, proteins, and carbs at a cellular level. This is key for making energy and keeping metabolism running smoothly. Besides energy production, NAD and NADP also contribute to DNA repair and the production of stress-response proteins. This shows niacin’s wide impact beyond just energy metabolism.

Not having enough niacin can cause health problems like fatigue, weak immune function, and poor digestion. So, it’s crucial to understand how Vitamin B3 works in metabolism for good health and energy.
