Brand Database
Brand profiles evaluate each NAD+ supplement against a published pharmaceutical-spec rubric: ingredient source, third-party testing, dosing accuracy, cGMP compliance, and claims substantiation. The database is being populated through editorial review.
Brand profiles coming soon
The brand database is being populated through editorial review: independent testing data, purity reports, and formulation analysis for leading NAD+ supplement brands. In the meantime, see the reference content on precursors and delivery methods.
Third-party tested
Every listed brand must publish current certificates of analysis from an independent laboratory.
cGMP facilities
FDA-registered and audited manufacturing facilities are a required minimum for brand inclusion.
Editorial independence
NADFaq's current editorial practice excludes paid placements; any change is disclosed at /conflict-of-interest.
Brand review methodology
When the brand database is populated, every profile on this page will follow a pharmaceutical-spec review protocol rather than a commerce-oriented ranking. The evaluation rubric covers active ingredient identity and purity (verified against an independent third-party certificate of analysis), cGMP compliance (FDA- registered facility with a verifiable audit record), label-claim accuracy (dose declared versus dose measured), and stability-under-storage data for the specific form sold. Profiles will also document the supply chain for the active ingredient — who synthesizes it, where, and under what quality system — because ingredient provenance is the variable that most often separates reliable products from the rest of the market.
NADFaq’s current editorial practice excludes affiliate links, commissions, and paid placements; any future change will be disclosed at conflict of interest. Products are purchased at retail using editorial budget and tested against their label claims. Reviews avoid the comparative superlatives common in supplement marketing — “best,” “top-rated,” “our #1 pick” — and stick to verifiable, measurable criteria.
