NAD+ reconstitution calculator

NAD+ ships as 500 mg, 1000 mg vials of lyophilized powder. Pick the size, type the water volume, read the concentration. The molecular weight is already filled in, so the molar result is there too.

Concentration = peptide mass ÷ diluent volume. Molarity = (mg/mL ÷ g/mol) × 1000. Research use only.

What the numbers mean for NAD+

NAD+ has a molecular weight of 663.43 g/mol (C21H27N7O14P2). So 500 mg is about 754 micromoles, whatever volume you dissolve it in. At 250 mg/mL that is 377 mM.

Each vial holds only powder, from 500 mg up to 1000 mg, and no diluent. Add bacteriostatic water down the inside of the glass, swirl, and do not shake. The reconstitution guide covers the handling; this page covers the arithmetic.

Common questions

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

Any volume that gives a concentration you can measure easily. 1 mL gives 500 mg/mL, 2 mL gives 250 mg/mL, 5 mL gives 100 mg/mL. The peptide amount stays 500 mg whatever you add.

What is the concentration of NAD+ 500 mg in 2 mL?+

250 mg/mL, which is the same as 250 µg/µL. With a molecular weight of 663.43 g/mol that is 377 mM.

Which NAD+ vial sizes does the calculator cover?+

The ones we sell: 500 mg, 1000 mg. Pick a chip or type any other mass.

Where does the NAD+ molecular weight come from?+

The reference value on the product's Specifications tab, 663.43 g/mol. The observed mass for the vial you receive is on its own lab report, which the QR code on the vial opens.
