NAD+ stands for nicotinamide adenine dinucleotide. It is a coenzyme that cells use to move energy through the body’s metabolism. In simple terms, NAD+ helps cells convert nutrients into usable energy and supports enzyme systems involved in repair, stress response, and ageing biology.

People look at NAD+ because it sits at the centre of cellular energy and mitochondrial function. NAD+ levels are closely linked with metabolism, fatigue and energy discussions, cellular repair systems, oxidative stress, and age-related changes in how efficiently cells work.

NAD+ helps shuttle electrons during energy production, which is part of how mitochondria generate usable cellular energy. It also feeds enzyme systems such as sirtuins and PARPs, which are involved in stress response, DNA repair signalling, and cellular maintenance.

NAD+ is often grouped with glutathione because both sit in the wider cellular-health category. NAD+ is more about energy metabolism and mitochondrial signalling, while glutathione is more about redox balance, antioxidant defence, and oxidative-stress control.
