NAD (nicotinamide adenine dinucleotide) is a vital cellular molecule that cycles between NAD+ and NADH to move electrons, support ATP production, repair DNA, and mediate signaling.
Key points
Energy: NAD+ accepts electrons in glycolysis and the citric acid cycle to enable ATP synthesis.
DNA repair & gene regulation: Enzymes like PARPs and sirtuins use NAD+ to fix DNA and regulate genes, affecting aging.
Signaling & inflammation: NAD+-dependent enzymes modulate stress responses, inflammation, and mitochondrial health.
Aging: NAD+ levels decline with age and some diseases, impairing metabolism and repair.
Treatments: Precursors (nicotinamide riboside, nicotinamide mononucleotide), lifestyle changes, and other approaches aim to boost NAD+. Early results are mixed; long-term safety and efficacy are unclear.
Practical advice Consult your healthcare provider before trying NAD+-boosting supplements or therapies. Support NAD+ naturally with regular exercise, adequate sleep, a balanced diet, and stress management.
