Cellular energy
NAD+ is the substrate mitochondria need to convert nutrients into ATP — your body's energy currency.

NAD+
Reset.
The coenzyme behind every energy reaction in your body. NAD+ levels drop with age, and exogenous NAD+ replenishes the substrate your mitochondria, sirtuins, and DNA-repair pathways depend on.

// 01What it is
NAD+ (Nicotinamide Adenine Dinucleotide) is the coenzyme that drives every energy-producing reaction in the cell. It's the substrate sirtuins use to regulate gene expression, and the molecule DNA-repair pathways consume to fix damage.
NAD+ levels drop sharply with age — by 50, you may be running on half the NAD+ you had at 25. Exogenous NAD+ replenishes that pool, restoring cellular energy production, cognitive function, and longevity-pathway activity.
It's the cornerstone of modern longevity protocols and a clean addition under any peptide cycle that pushes the body hard.
// 02How it works
Four pathways — energy, repair, cognition, longevity — all running off the same coenzyme.
02 / REPAIR
DNA repair
PARP enzymes consume NAD+ to repair DNA damage from oxidative stress, sun, and inflammation.
03 / SIGNAL
Activate sirtuins
Sirtuins regulate genes tied to longevity, metabolism, and inflammation — they need NAD+ to function.
04 / RESULTS
Energy & clarity
Net effect: more cellular energy, sharper cognition, better recovery, slower biological aging markers.
// 03Key benefits
Cellular energy
Restores the substrate mitochondria need to produce ATP at full output.
Cognitive clarity
Many users report sharper focus and reduced "brain fog" within 1–2 weeks.
DNA repair support
Replenishes NAD+ that PARP enzymes burn through fixing daily oxidative damage.
Longevity pathways
Sirtuins can't function without NAD+. More substrate = better gene-expression signaling.
Recovery support
Pairs cleanly under any high-output peptide cycle — especially Reta, Tirz, or HGH.
Mood + sleep
Many users report better sleep architecture and steadier mood through a NAD+ run.
