NAD+ quick reference: mg ↔ units

Bidirectional reference for a 100 mg NAD+ vial reconstituted with 5 mL BAC water (concentration 20.00 mg/mL).

Dose (mg)	Dose (mcg)	U-100 units
25	25000	125
50	50000	250
100	100000	500
200	200000	1000

Read across in either direction. The mg ↔ units relationship is linear at a fixed concentration — change vial size or BAC water and every row in this table moves.

Worked example

NAD+ mg ↔ units, both directions on one vial

Working from one 100 mg NAD+ vial mixed with 5 mL of bacteriostatic water → 20.00 mg/mL.
mg → units: 50 mg ÷ 20.00 × 100 = 250 units.
units → mg: 250 units ÷ 100 × 20.00 = 50 mg — round-trip exact, that's how you sanity-check a logged value.
mcg flip: 50 mg = 50000 mcg, useful when the protocol writes the dose below the 1 mg threshold.
Every row here is specific to this vial; reconstitute with a different volume and you start from a different concentration.

Scenarios people actually run into

Three things that come up logging NAD+

Protocol says 50 mg. Syringe says 250 units. Those are the same draw on this vial — and only on this vial.
Someone online says "NAD+ dose is 20 units." That number is meaningless without their vial mg and their diluent mL. Ignore the units number and convert from the mg.
Logged a dose in units last week and a dose in mg today. The mg ↔ units flip on this page is how you confirm both entries describe the same actual draw.

NAD+ is a coenzyme every cell uses to convert food into energy, and people inject it to push back against the natural age-related drop in NAD+ levels. Most users report it for energy, mental clarity, and recovery; researchers also study it for DNA-repair and metabolic-aging pathways. Human studies confirm injections raise blood NAD+ levels meaningfully, though long-term outcome data is still developing. This page covers reconstitution math and typical daily-or-cycle logging cadence.

How the NAD+ mg ↔ units converter works

NAD+ doses are written in mg (50, 100), and unit counts run into the hundreds. This converter handles the mg-to-units math but most users plan around mL volumes (1, 2, 2.5 mL) rather than units.

The formula in both directions: mg = mL × concentration mg/mL, and units = mL × 100 on a U-100 syringe. With a 20 mg/mL NAD+ solution, 50 mg comes out to 250 units, and 250 units comes out to 50 mg. The converter handles the unit flip automatically so you never multiply or divide in your head while holding a syringe.

Concentration is the input that changes the answer most. A 100 mg vial diluted with 1 mL is twice as concentrated as the same vial diluted with 2 mL, which means the same dose draws half as many units. That is the single biggest source of converter confusion: a remembered unit count from an old vial does not transfer to a new vial reconstituted with different water volume.

Tracking NAD+ unit counts

NAD+ is unusual in this list because the cadence is so variable. The dose log itself is the source of truth for what protocol was actually followed; without it, retrospective analysis is essentially guesswork.

Documenting NAD+ administration requires careful attention to the route, as a key differentiator in study protocols is intravenous (IV) versus subcutaneous (SubQ) delivery. IV infusions are typically observed in clinical or research settings, involving large quantities such as 250 mg, 500 mg, or even 1000 mg, infused directly into the bloodstream over several hours. Tracking for this route should include the total dose, infusion duration, and any observed parameters. In contrast, subcutaneous self-administration involves logging much smaller doses (e.g., 50 mg) on a more frequent schedule. A comprehensive tracking log allows for clear delineation between these two methods, ensuring that the recorded data accurately reflects the significant difference in dose magnitude and delivery pharmacokinetics.

Common NAD+ mg ↔ units mistakes

Trying to fit a 50 mg dose into a single insulin-syringe draw without re-running the math.
Miscalculating the dose volume and not planning for the need for multiple insulin syringes or a single larger syringe to administer the full calculated amount.
Reusing a unit count from a previous vial without re-checking diluent volume.

Frequently asked questions about NAD+ mg ↔ units

What's the formula behind this NAD+ mg ↔ units converter?

Both directions use the same concentration. Going mg → units: (dose mg ÷ concentration mg/mL) × 100. Going units → mg: (units ÷ 100) × concentration. For this NAD+ example at 20.00 mg/mL, 50 mg works out to about 250 units, and the same number of units converts back to 50 mg. NAD+ is the only common peptide where the converter math runs above 100 units — switch to mL-based draws above that line.

Why does my NAD+ unit count not match a number I read online?

Almost always because the other source assumed a different vial concentration. A "NAD+ dose = 20 units" tip is meaningless without knowing whether the vial was reconstituted with 1, 2, or 3 mL of water. The converter on this page asks for your actual vial mg and diluent mL so the answer reflects your vial, not someone else's. NAD+ is the only common peptide where the converter math runs above 100 units — switch to mL-based draws above that line.

Does the NAD+ converter handle mcg as well as mg?

Yes — 1 mg equals 1,000 mcg, and the converter does the unit flip automatically when you switch the input. This matters for peptides where typical doses sit below 1 mg: a 250 mcg NAD+ dose displayed as 0.25 mg is the same number, just easier to read. NAD+ is the only common peptide where the converter math runs above 100 units — switch to mL-based draws above that line.

When would I convert NAD+ units back to mg?

Most often when checking a dose someone else recorded. Logs and protocols sometimes write the dose in units (because it's what shows on the syringe), other times in mg (because it's what the protocol step is named). The reverse direction lets you confirm a logged unit count actually matches the planned mg target before drawing the next dose. NAD+ is the only common peptide where the converter math runs above 100 units — switch to mL-based draws above that line.
