How much water do I add to a 500 mg NAD+ vial?

The water amount is your choice, it only changes how strong each mL is. With 5 mL you get 100 mg per mL; with more water each unit holds less, which makes small doses easier to measure.

How many units is 1 mg of NAD+?

It depends on the strength of your mix. At 100 mg/mL, 1 mg is 1 unit. Enter your own vial and water in the calculator to get your number.

How long does mixed NAD+ keep?

Follow the storage line on your product or prescription. Bacteriostatic water itself should be used within 28 days of the first needle, per CDC guidance.

NAD+ dosage calculator

Enter your NAD+ vial size, the amount of water added and your dose to find the units you’ll draw with a U-100 insulin syringe.

Use this for reference only. Your dose is set by your prescriber or the product label; we only convert it into units.

Available vial sizes: 500, 1,000 mg
Status of approval: Not FDA-approved
500 mg mixed with 5 mL as an example: concentration: 100 mg/mL

How NAD+ math works

Divide the amount in the vial by the water to find the strength. When you add 5 mL of water to a 500 mg vial, each mL contains 100 mg. Divide your dose by the strength to find mL, then multiply that amount by 100 to calculate units on a U-100 syringe.

From that vial, a 2 mg dose measures 0.02 mL, or 2 units.

A quick look at NAD+ units

Your dose	500 mg vial + 5 mL	1,000 mg vial + 10 mL
2 mg	2 units	2 units
2.5 mg	2.5 units	2.5 units
4 mg	4 units	4 units
5 mg	5 units	5 units
10 mg	10 units	10 units
12.5 mg	12.5 units	12.5 units
20 mg	20 units	20 units
25 mg	25 units	25 units
75 mg	75 units	75 units

For that vial and water amount, the cell identifies the U-100 syringe line to draw to.

Does NAD+ have FDA-approved status?

It isn't FDA-approved for any use in people; it's sold as a research chemical. There is no FDA label, so no official dose is available. We only convert a dose you already have.

Questions people often ask

What amount of water goes into a 500 mg NAD+ vial?

You choose the water amount, which only changes the strength of each mL. Using 5 mL gives you 100 mg per mL. More water reduces the amount in each unit, so you can measure smaller doses more easily.

How many units does 1 mg of NAD+ equal?

The answer depends on how strong your mix is. When the strength is 100 mg/mL, 1 mg equals 1 unit. Use the calculator and enter your vial and water amounts to find your number.

How long does mixed NAD+ last?

Follow the storage instructions on your product or prescription. Per CDC guidance, use bacteriostatic water within 28 days after the first needle.
