NAD+ — Cellular Energy Cycle

nad-plus replenishes the coenzyme that powers energy production and sirtuin-driven repair — both of which decline with age — as a daily subcutaneous cycle.

Why this protocol

nad-plus is a coenzyme every cell uses to turn fuel into energy and to run DNA-repair and the sirtuin enzymes tied to healthy aging. Its levels fall with age, and the longevity rationale is simple: top the pool back up. Clinics typically deliver it by IV; the subcutaneous route here is the at-home community approach to the same goal.

It is a mono protocol — a single coenzyme on a daily schedule. The main practical issue is the flushing/urge sensation a fast dose can cause, which is why it is injected slowly and titrated up rather than started high.

Convention drawn from the NAD+ page's cited evidence — subcutaneous self-dosing is the community adaptation of clinic IV protocols, so the dose and schedule are convention rather than a trial-proven regimen. No therapeutic claims.

Cycle & schedule

  1. Cycle (4–8 weeks)

    NAD+ 50–100 mg once daily subcutaneously, starting at the low end and injecting slowly to limit flushing.

  2. Washout (2–4 weeks)

    Take 2–4 weeks off; the break is when to recheck any metabolic or energy markers you are tracking.
