NAD+
A naturally occurring coenzyme essential for cellular energy production, DNA repair, and mitochondrial function — a foundational longevity research compound.
What It Is
NAD+ (nicotinamide adenine dinucleotide) is a naturally occurring coenzyme found in virtually every living cell, essential for cellular energy production, mitochondrial function, DNA repair, and healthy aging. It acts as an electron carrier during the metabolic processes inside mitochondria that convert nutrients into usable energy.
NAD+ also serves as a substrate for enzymes involved in DNA repair, cellular stress responses, and metabolic signaling — including sirtuins and PARPs. NAD+ levels naturally decline with age, which has made NAD+ restoration an important area of longevity research.

What to Expect
NAD+ is generally approached as a cellular-energy and rejuvenation protocol rather than a compound expected to produce a single, immediate effect, with interest centered on mitochondrial energy production, cellular repair, and metabolic function.
With injectable NAD+, some experience a noticeable tingling or warming sensation, particularly as the dose increases; injection-site redness or burning may also occur and typically resolves.
What to Pair It With
Reconstitution
Suggested Research Dosing Strategy
Administration Notes
Subcutaneous (abdomen) or intramuscular administration. “No-sting” bacteriostatic water is suggested to improve injection comfort.
A tingling sensation as the dose increases can be normal, but is not required for effect — reduce the dose if it becomes uncomfortable.
Gradual titration may improve individual tolerability.
Research Considerations
NAD+ sits at the center of several fundamental cellular processes — energy metabolism, and enzymes involved in cellular maintenance and repair including sirtuins (cellular stress response, metabolic regulation) and PARPs (DNA repair, which increases NAD+ demand under cellular damage).
Research has expanded from simple energy production into mitochondrial function, DNA repair, metabolic health, cellular stress response, and neurological health — though clinical benefits of supplementation for specific outcomes remain an active research area.
