Nicotinamide

Nicotinamide is a form of vitamin B3 that your body uses to make important molecules involved in energy production. It acts as a building block for NAD+, a coenzyme that helps cells turn food into energy and repair DNA. Because of its role in cellular energy and repair, nicotinamide is studied for potential benefits in aging, nerve health, and overall cell resilience. You can get nicotinamide from food sources or take it as a supplement, and it is generally well tolerated at common doses. At higher doses it can have side effects, so it is sensible to follow dosing guidelines and talk with a health care provider before starting supplements. Researchers are exploring whether nicotinamide can support memory, protect nerve cells, or improve metabolic health in older adults. It may interact with other medications or health conditions, so personal medical advice is important before adding it to a routine. Nicotinamide differs from other forms of vitamin B3 in how it affects the body and in its safety profile, which is why specific forms are chosen for different uses. For most people, a balanced diet provides enough, but targeted supplementation is sometimes considered under medical supervision. Understanding what nicotinamide does helps you weigh potential benefits and risks if you are thinking about it for aging or other health goals.
