NAD+ Dosage Guide: How Much, How Often, and Common Mistakes

NAD+ at a glance:

• Drug class: Metabolic / longevity research peptide
• Route: subcutaneous injection in research
• Typical frequency: no established human regimen
• Half-life: typically short systemically

Most people who quit NAD+ do it during titration, and most of those quits trace to dosing decisions. Get the schedule right and the rest is much easier.

Standard Dosing Schedule for NAD+

No FDA-approved human dosing.

The typical schedule for NAD+ is no established human regimen via subcutaneous injection in research. Half-life of typically short systemically explains why this schedule works — the drug stays active long enough to support that interval.

Titration: Why Starting Low Matters

For this class of compound, gradual titration is the standard approach. The starting doses listed above are not therapeutic — they exist to let the body adapt and to reduce gastrointestinal symptoms .

A typical titration plan for NAD+ holds each dose step for at least four weeks before moving up. Faster titration is associated with more dropouts due to side effects.

Missed Doses

If a dose of NAD+ is missed: for daily schedules, the rule of thumb is to take it as soon as remembered if within a defined window, otherwise skip it and resume the regular schedule. The exact window depends on the half-life (typically short systemically) and the specific product label. Never double up to make up for a missed dose.

Dose Adjustments

Dose adjustments may be needed for the following:

• Significant weight loss or weight gain
• Side-effect intolerance at the current step
• Changes in renal or hepatic function
• Drug interactions (particularly relevant for any concurrent medications)

We cover the side-effect side of dose decisions in NAD+ side effects and the cost angle of dose escalation in NAD+ cost.

What the Trials Used

Published clinical data on this compound is limited. Most reported dosing comes from observational or non-clinical sources.

That data drives the labeled dosing range, which is what physicians prescribe by.

Special Populations

The dosing guidance above applies to general adult use. Special populations — pregnancy, pediatric, severe renal impairment, hepatic dysfunction, elderly with frailty — require individualized assessment that this page can't substitute for.

For NAD+: the standard contraindications for this drug class apply.

Bottom Line

Dosing NAD+ is a long game. Get the titration right, hold steady, and adjust deliberately based on how your body responds.
