NAD+ Dosage Chart and Injection Calculator, 1000 mg Vial
NAD+ dosage chart figures for injections come from a small set of human trials. Most of them gave it by drip, in amounts far below what one 1000 mg vial holds. No FDA-approved NAD+ product to inject turned up in openFDA when we searched on 23 October 2026. So the real question is the math: how strong the liquid is, and how much of it a figure takes.
Short answer
Six human records name an injected NAD+ amount, and most of them were slow drips into a vein. None of them is a dose for you. The trial chart below lists each amount next to its record. The calculator and the strength table turn any amount into mL and syringe units.
Below you get the trial chart, a calculator, and a table for a 1000 mg vial at six water volumes. For how the routes compare, read our NAD+ injections guide.

NAD+ calculator for a 1000 mg vial
Type the vial size, the water you added, and an amount in mg. The tool gives the strength, the volume, the units, and how many fills of your syringe it takes. It opens with the vial size, a middle water volume, and the amount from the recruiting injection trial in the chart.

What amounts did NAD+ injection trials use?
Six human records give a figure for injected NAD+. Two are published trials in heart failure. Four are registry entries, and most have no posted results. Each row shows who took part, the route, the amount, and how long it ran.
The two heart failure trials on PubMed and four entries on ClinicalTrials.gov record these injected amounts:
| Who took part | Route | Amount | Length | Record |
|---|---|---|---|---|
| Adults with heart failure (180) | Into a vein | 10 mg a day | 7 days | PMID 40954388 |
| Older adults with heart failure (60) | Injection, route not named | 50 mg in 50 mL saline a day | 7 days | PMID 39228487 |
| Healthy adults (up to 70, recruiting) | Under the skin, into muscle, or a quick shot into a vein | 100 mg in 2 mL bacteriostatic (bac) water | Single doses per arm | NCT06919328 |
| Healthy adults (53) | Infusion into a vein | 500 mg in 500 mL saline | One infusion | NCT06382688 |
| After cord blood transplant (12 planned) | Infusion into a vein | 10, 20 or 50 mg a day by group | 21 days | NCT06558253 |
| Liver cancer, with two cancer drugs (37 planned) | Into a vein | 100 mg a day on days 1 to 3 | Each 21-day cycle | NCT06590844 |
Disclaimer: these are amounts recorded in human trials and trial registries, in the patients named. An openFDA search found no FDA-approved NAD+ injection, so none of them is a dose for you. A licensed clinician makes any dosing call.
Look at how strong the trial liquids were. The heart failure drip and the healthy adult drip were both 1 mg per mL. The only trial with a shot under the skin used 50 mg per mL. Those liquids are far weaker than a 1000 mg vial mixed with a few mL of water.

Why the oral NAD+ doses are a different list
Search results often mix two kinds of numbers. Pills sold for NAD+ are mostly NR or NMN. Those are building blocks the body turns into NAD+. Their trials gave them by mouth, and their amounts are not injection amounts.
Those oral figures sit on our NAD+ profile, with their own trials. Please keep them out of this calculator, which is built for an injection vial. For how the two molecules differ, see NMN vs NAD+.
How strong is a 1000 mg vial at each water volume?
Method: we divided 1000 mg by each water volume, then divided each trial amount by that strength and multiplied by 100 for units. A script did every cell. Units are rounded to one decimal place.
Using the trial amounts from the chart above and the U-100 syringe scale, our script gives these volumes:
| Water | Strength | Most in 1 mL | 10 mg | 50 mg | 100 mg | 500 mg |
|---|---|---|---|---|---|---|
| 2 mL | 500 mg/mL | 500 mg | 2 units | 10 units | 20 units | 100 units |
| 2.5 mL | 400 mg/mL | 400 mg | 2.5 units | 12.5 units | 25 units | 1.25 mL, 2 syringe fills |
| 4 mL | 250 mg/mL | 250 mg | 4 units | 20 units | 40 units | 2 mL, 2 syringe fills |
| 5 mL | 200 mg/mL | 200 mg | 5 units | 25 units | 50 units | 2.5 mL, 3 syringe fills |
| 8 mL | 125 mg/mL | 125 mg | 8 units | 40 units | 80 units | 4 mL, 4 syringe fills |
| 10 mL | 100 mg/mL | 100 mg | 10 units | 50 units | 100 units | 5 mL, 5 syringe fills |
Disclaimer: this table is arithmetic on a 1000 mg vial. It turns trial amounts into volumes and units. It does not suggest what anyone should inject.
How to read it: find your water volume in the first column, then read across to the trial amount. Water changes the volume each amount takes, not the total mg in the vial.

When does one draw stop fitting a 1 mL syringe?
A U-100 insulin syringe holds at most 1 mL. With a 1000 mg vial, one full syringe holds 1000 divided by the water volume in mL. Using the trial amounts from the chart and the trial strength from the shot study, the break points work out like this:
100 mg fits one 1 mL draw at 10 mL of water or less. 500 mg fits one draw at 2 mL or less. Matching the shot trial's 50 mg per mL would take 20 mL of water.
Disclaimer: these are syringe capacity numbers worked out from the trial records. They show what fits in a syringe, not how much anyone should take, and a licensed clinician makes any dose decision.
Past those points, the same amount needs two or more fills. One listing we read printed a 10 mL vial, which could not hold 20 mL.
Smaller syringes reach the limit sooner. A 0.5 mL syringe holds half as much, so the break points halve too. The calculator above lets you pick the syringe and shows the fills. For reading the marks, see the insulin syringe units chart.

What we checked on 23 October 2026
To confirm the 1000 mg size, we opened public NAD+ seller listings on 23 October 2026. Seven loaded with readable text. Four more were blocked, behind a login, or gone. This is our own small snapshot, not a survey of the market.
- All 7 of 7 offered a 1000 mg vial.
- 3 of 7 also offered a 500 mg vial.
- Only 1 of 7 printed a water volume for the 1000 mg vial.
- 2 of 7 printed the size of the vial glass, and both said 10 mL.
- 3 of 7 said each lot or batch has its own lab report.
We also ran the calculator against the strength table above. All 24 unit cells across the six water rows matched. Since most listings give no water volume, the label mg and your own water volume are the two numbers to check. Our storage guide for Vietnam heat covers keeping a vial once it is mixed.

Common questions
How much bac water goes into a 1000 mg NAD+ vial?+
No trial or label sets a water volume for a 1000 mg vial. The water only changes the strength, and the vial still holds 1000 mg either way. The strength table on this page gives the mg per mL at six common volumes.
How do I reconstitute 1000 mg of NAD+?+
Add a known volume of bac water, then divide 1000 by that volume to get mg per mL. Check that the water fits inside the vial glass first. One listing we read printed a 10 mL vial, so water above that would not fit. Our storing guide covers handling after mixing.
How many units of NAD+ should I inject?+
No trial or label gives a unit count for anyone to follow. Units are only a way to read volume, and the volume depends on how much water went in. The strength table converts each trial amount into units at six water volumes, and the calculator does the same for your own numbers.
Can you inject too much NAD+?+
No human trial has posted a maximum. The transplant trial planned to stop raising the dose if a group had a serious reaction, but it has no results yet. So the records cannot say where a limit sits, and this page does not guess one.
Are the NAD+ doses on the profile page the same as these?+
No. The NAD+ profile lists amounts of NR and NMN, which are pills people swallow so the body can make NAD+. This chart covers NAD+ given by injection or drip. Milligrams of a pill and of an injection do not swap one for one.
