NAD+ Dosing Calculator
Vial size, bacteriostatic water, and dose — converted to insulin-syringe units, pre-loaded with NAD+'s documented doses.
Typical dose: 250 – 500 mg · oral
NAD+ documented dose levels
| Phase | Dose | Frequency | Route |
|---|---|---|---|
| Weeks 4-8 | 250 mg NR or NMN | Once daily | Oral |
| Ongoing | 500 mg NR or NMN | Once or twice daily | Oral |
| Studied as 4 consecutive days; no established schedule | 500 mg NAD+ in 500 mL saline | Per infusion — run time is the critical setting, not the milligrams | Intravenous |
Reconstitution quick reference
A 5 mg vial at a 500,000 mcg dose of NAD+, by how much bacteriostatic water you add:
| Bacteriostatic water | Concentration | U-100 syringe units per dose |
|---|---|---|
| 1 mL | 5 mg/mL | 10000 units |
| 2 mL | 2.5 mg/mL | 20000 units |
| 3 mL | 1.667 mg/mL | 30000 units |
Different vial size or dose? The calculator above handles any combination.
NAD+ dosing questions
What is a typical NAD+ dose?
250 – 500 mg · oral
How many insulin-syringe units is a NAD+ dose?
With a 5 mg vial reconstituted with 2 mL of bacteriostatic water, a 500,000 mcg dose measures 20000 units on a U-100 insulin syringe. The calculator above recomputes this for your own vial size, water volume, and dose.
How often is NAD+ taken?
Once daily
