Verify the NAD+ sample and selected amount
Open the actual documents and keep the report-to-option relationship explicit.
The current PEL NAD+ listing links the following originals. Report labels are navigational aids; read each full image for its sample, amount, methods and date.
Compare to the selected option
Choose 500 mg or 1000 mg on the current product page, then inspect the corresponding evidence. A report for one amount is not automatically evidence for the other amount or every future supplied lot.
Resolve a gap
If a date, sample or current-lot relationship is unclear, ask PEL with the exact product option and original report link.
