NAD+: reconstitution and unit calculator

Updated 12 Oct 2026

The calculator is here to help you read research. It only converts units: your own numbers, or doses reported in the cited studies.

Not a recommendation, not treatment guidance. The calculator only converts units. It does not tell you how much of any substance is advisable or safe to use. NAD+ is preselected in the calculator. The preset fills in only the vial size and example water, not a dose. Doses used in studies, with sources: dose page. About the substance: NAD+.

Picking one fills the vial size and an example water amount. You can change both.
milligrams (mg), printed on the vial label
millilitres (ml) of bacteriostatic water
Pick the unit: mg or mcg. 1 mg = 1000 mcg. mcg and µg mean the same: microgram.

Dosing calendar

Your browser makes a calendar file (.ics) that you can import into Google, Apple or Outlook calendar. Each entry carries the calculator result in syringe units and a reminder. The file is made in your browser, nothing is sent.

The schedule is your own choice, not a recommendation.

whole number, 1 - 365
doses, 0 = no early notice

How the math works

  1. Concentration = vial mg ÷ water ml. For example 5 mg ÷ 2 ml = 2.5 mg/ml = 2500 mcg/ml.
  2. Volume = desired mcg ÷ concentration (mcg/ml). For example 250 mcg ÷ 2500 mcg/ml = 0.1 ml.
  3. On a U-100 syringe 1 ml = 100 units, so 0.1 ml = 10 units.
  4. Doses left = vial mcg ÷ desired mcg, rounded down.

Calculator FAQ

Does the calculator tell me how much to use?

No. It only converts units: vial milligrams and added water millilitres into a concentration, and the amount you enter into millilitres and syringe units. It does not tell you how much of any substance is advisable or safe to use.

What doses of NAD+ have been used in studies?

Published human doses, with sources, are on the page NAD+: dosage in studies. They are not recommendations.

Is anything I type sent anywhere?

No. The calculation and the calendar file are made in your browser, and the numbers you enter are not sent anywhere.

What does U-100 mean?

On a U-100 insulin syringe, 1 ml is 100 units. The calculator shows the volume both in millilitres and in units on that scale.

In the glossary: bacteriostatic water. Research on substances: Peptides A-Z.
