NAD+ 500 mg vs 1000 mg: compare labelled quantity
Compare the same material and format before using a unit-price calculation.
| PEL option | Labelled amount | Current source |
|---|---|---|
| 1000 mg | 1000 mg | Open this current option |
| 500 mg | 500 mg | Open this current option |
What the difference means
1000 mg is twice the labelled mass of 500 mg. It does not by itself mean twice a measured result, prove a report relationship or provide an administration instruction.
Compare the final package
Include the number of containers and the final delivered cost, then calculate against the labelled quantity. Use the unit-price worksheet and inspect the current NAD+ source documents before comparing offers.
