NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell of your body. It powers mitochondrial energy production and activates sirtuins, proteins involved in cellular repair and longevity signalling.
Why It Declines
NAD+ levels fall roughly 50% between ages 40 and 60. Causes include increased consumption by DNA-repair enzymes (PARPs) and decreased biosynthesis.
Supporting Healthy NAD+
How To Support It
Precursors (NMN, NR), exercise, fasting, and quality sleep all support NAD+ pathways.
