NAD+ Reconstitution & Dosage Calculator
This free NAD+ calculator turns your vial size, the bacteriostatic water you add, and your target amount into a concentration, a draw volume, and the exact units on a U-100 insulin syringe. NAD+ is dosed in larger milligram amounts, so draws are big — the calculator flags when an amount exceeds your syringe.
Quick summary
- Converts vial size (mg), bacteriostatic water (mL), and a milligram amount into concentration, draw volume, and U-100 units.
- Built for the larger milligram NAD+ amounts, with reference math for 100 and 500 mg vials.
- Educational measurement tool only — it does not diagnose, treat, or recommend an amount.

What this NAD+ calculator does
This calculator does one job well: it turns your vial size, the amount of bacteriostatic water you add, and your target amount into a concentration (mg/mL), a draw volume (mL), and the matching units on a U-100 insulin syringe. Change any input and the result updates instantly.
NAD+ ships as a freeze-dried powder. Before it can be measured into a syringe it has to be reconstituted — dissolved in bacteriostatic water. How much water you add sets the concentration, and the concentration sets how many units each amount works out to. The presets above cover the most common NAD+ vial setups; use the custom fields for anything else.
How to use the NAD+ calculator
Pick your syringe
Choose the U-100 insulin syringe you'll draw with. Smaller syringes (0.3 mL / 30u) have finer lines, which helps when the draw is small.
Enter your vial and water
Set the milligrams in your NAD+ vial and the bacteriostatic water you added. Together these set the concentration.
Set your target amount
Toggle mg or mcg and pick (or type) the amount you're measuring for. The calculator does the conversion for you.
Read the draw
The result panel shows concentration, draw volume, and the exact U-100 units to pull, plus how many doses your vial contains.
NAD+ reconstitution math, explained
The math is short. Concentration = vial size ÷ bacteriostatic water. Draw volume = target amount ÷ concentration. Units = draw volume × 100 (a U-100 syringe reads 100 units per mL). The table below shows common NAD+ setups and the units for a 1 mg amount at each.
| Vial size | Bac water | Concentration | Units per 1 mg |
|---|---|---|---|
| 100 mg | 1.0 mL | 100 mg/mL | 10 units |
| 100 mg | 2.0 mL | 50 mg/mL | 20 units |
| 100 mg | 3.0 mL | 33.33 mg/mL | 30 units |
| 500 mg | 5.0 mL | 100 mg/mL | 10 units |
| 500 mg | 10.0 mL | 50 mg/mL | 20 units |
NAD+ amount-to-units reference
How common amounts convert to U-100 syringe units at two example concentrations. These are arithmetic conversions for reference, not a recommendation of any amount.
| Amount | Volume (mL) | U-100 units |
|---|---|---|
| 25 mg (25000 mcg) | 0.5 mL | 50 units |
| 50 mg (50000 mcg) | 1 mL | 100 units |
| 100 mg (100000 mcg) | 2 mL | 200 units |
| Amount | Volume (mL) | U-100 units |
|---|---|---|
| 25 mg (25000 mcg) | 0.25 mL | 25 units |
| 50 mg (50000 mcg) | 0.5 mL | 50 units |
| 100 mg (100000 mcg) | 1 mL | 100 units |
Mixing, color & storage tips
Big amounts, large draws
NAD+ is dosed in tens to hundreds of milligrams, so draws are large and often exceed a single 1 mL syringe. Many references split the amount or inject slowly — the calculator flags anything over your syringe capacity.
Buffered vs unbuffered
Some NAD+ preparations are pH-buffered, which can affect comfort and stability. Follow the specific product's reconstitution and storage guidance.
A clear solution
NAD+ reconstitutes to a clear liquid (often faintly colored depending on preparation). Discard if it becomes cloudy or shows particles.
Storage
Refrigerate the reconstituted vial and keep it dark; use within a limited window. Keep the dry powder cold for longer storage and do not freeze a mixed vial.

NAD+ — frequently asked questions
What does this NAD+ calculator tell me?
It converts your vial size, bacteriostatic water volume, and target amount into concentration (mg/mL), draw volume (mL), and U-100 syringe units.
Is the NAD+ reconstitution calculator free?
Yes — free, browser-based, no account.
How much bacteriostatic water for a 100 mg NAD+ vial?
A 100 mg vial with 2 mL makes 50 mg/mL; with 1 mL it makes 100 mg/mL. Because NAD+ amounts are large, concentration choice mostly affects how many draws a vial yields.
How many units is 50 mg of NAD+?
At 50 mg/mL it is 100 units (1 mL). At 100 mg/mL it is 50 units. Large amounts often exceed a 1 mL syringe, so the calculator flags that.
