How many milligrams are in the vial
A strength and a volume are two numbers that multiply into one. Most NAD+ sellers print neither, some print one, and a few print both and leave the multiplication to you. Put the two numbers in and the answer appears with the working underneath it.

Why the multiplication is the whole problem
56 distinct dose lines appear across the 106 sellers on this roster, and they were ruled one at a time. 3 of them are what this site calls a strength only — a concentration with no volume beside it, carried by 10 distinct prices. Another 6 are a volume only, carried by 6 distinct prices: millilitres that cannot become milligrams because the strength is missing. Only 6 state both, on 10 prices — and on those, the multiplication is ours rather than the seller’s. 5 of the 18 totals on this site’s board were arrived at that way, and each one says so on the line where it appears.
Which is why this box exists rather than a longer explanation. How much NAD+ is in a vial sets out all 56 lines and the ruling on each; this page just does the sum.
What this does not tell you
This is what is in a container, not what reaches you and not what you should take. There is no clinician behind this site, it publishes no dosing schedule, and a milligram delivered one way is not a milligram delivered another — see the medical disclaimer.
It also cannot check the numbers you give it. If a seller states a strength and you supply the volume from memory, the answer is your recollection multiplied by their figure. And a concentration stated for one product does not carry to another the same seller sells.
Once you have a milligram total, the cost per milligram calculator turns it and a price into the figure this site is named after.
Why this page carries no advertising
Nothing on this page is paid and nothing on it ever will be. A calculator sitting beside a button that pays the person who built it is not a calculator. The pages that carry links to sellers are the route explainers, the cost table and the seller pages, and this one stays clean so those can be believed. It is a build guard rather than an intention — see the disclosure.
