NAD+ offerings: test the claim before judging the package
A framework for reading a longevity-labelled service with a more precise set of questions.
Translate the headline into a specific claim
A phrase about energy, cellular support or healthy ageing can cover several different ideas. Write down the exact outcome being suggested, the product involved and the basis offered for the statement. If the explanation remains broad, you cannot tell what evidence would actually support it.
Keep general biology separate from the offered service
An explanation of a substance’s role in the body is not automatically evidence about a commercial intervention. Ask whether supporting information concerns the same product, route and outcome as the offer. The gap between background explanation and the proposed service is a question worth examining.
Review the commitment without assuming the benefit
Clarify who is responsible for assessment, what uncertainties are acknowledged and what the financial agreement includes. A premium presentation does not settle those questions. NAD+ appears in this library to help readers examine the offering, not as an endorsement of a longevity result.
