NAD+ (Nicotinamide Adenine Dinucleotide) · Cost per dose
NAD+ (Nicotinamide Adenine Dinucleotide) cost per dose
A 500 mg vial of NAD+ (Nicotinamide Adenine Dinucleotide) divided by the amount you use gives your cost per dose — but a reconstituted vial only stays usable for around 28 days refrigerated, so any doses left when it expires were paid for and never used. Enter your own price and amount below for the real figure.
Vials are priced per vial, but you use them per dose. Put in what you paid and the amount you use, and this works out the real number — including the doses you lose if the vial expires before you finish it. Nothing is stored or sent anywhere.
Why NAD+ (Nicotinamide Adenine Dinucleotide) costs more than the sticker price
The vial size above is the presentation NAD+ (Nicotinamide Adenine Dinucleotide) is most commonly sold in, at 500 mg. Divide the price by the doses in the vial and you get the headline figure — but a reconstituted vial only stays usable for a limited window, commonly quoted as around 28 days refrigerated. Any doses still in the vial when that window closes were paid for and never used, so the honest number is the price divided by the doses you actually reach.
That is also why a smaller vial sometimes works out cheaper per dose than a larger one, even when the larger one looks better per milligram. If the calculator above shows waste, try a smaller vial size and watch the real figure move.
Common questions
How much does NAD+ (Nicotinamide Adenine Dinucleotide) cost per dose?
Divide what you paid for the vial by the number of doses in it. A 500 mg vial contains 500 mg, or 500000 mcg, so the number of doses depends entirely on the amount you use. The calculator on this page does the arithmetic, including the doses you lose if the vial expires first.
Is a bigger NAD+ (Nicotinamide Adenine Dinucleotide) vial cheaper?
Per milligram, usually yes. Per dose you actually use, not always — a larger vial you cannot finish inside its stability window can work out more expensive than a smaller one you do finish, because the leftover doses were still paid for.
Why is my real cost higher than price divided by doses?
Because a reconstituted vial has a limited usable window, commonly quoted as around 28 days refrigerated. Doses still in the vial when that window closes are wasted, so the honest figure is the price divided by the doses you reach in time.
