NAD+ for a cellular energy cycle

NAD+ replenishes the coenzyme that powers energy production and sirtuin-driven repair. Both decline with age. This is a daily subcutaneous cycle to top them back up.

4–8 weeks + 2–4-week washout

01

Why this protocol

NAD+ 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 replenishing it is the whole longevity rationale here. 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.

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.
