NAD+ is required by hundreds of enzymatic reactions, and published work reports that its tissue concentrations decline with age across multiple organ systems.

Duration
NAD+ is a coenzyme every cell uses to convert food into usable energy. Tissue levels decline with age, and this is a direct-delivery route for people whose providers want to supplement it.

WHY NAD+
Every cell runs on it. Supply drops with age.

Illustrative of population-level findings. Most published human supplementation data involves NAD+ precursors rather than NAD+ itself.
HOW NAD+ WORKS
The coenzyme behind cellular energy production.
Glucose control.
NAD+ is a nicotinamide adenine dinucleotide coenzyme present in every cell. It shuttles electrons through the reactions that produce ATP, and it is consumed as a substrate by sirtuins and PARP enzymes involved in DNA repair. Because it is used up rather than recycled in those reactions, supply matters.
Carries electrons in energy production
NAD+ cycles between its oxidized and reduced forms to move electrons through glycolysis and the mitochondrial electron transport chain.
Substrate for sirtuins and PARPs
These enzyme families consume NAD+ while performing DNA repair and regulating cellular stress responses, which is why demand can exceed supply.
Declines measurably with age
Published tissue analyses report progressively lower NAD+ concentrations across adult decades.
Delivered by injection
Injection avoids the digestive breakdown that limits oral NAD+. Dose and frequency are set by your provider at intake.
