# A Natural Endeavor

> Traceable US supplement label facts, deterministic quantity comparison, source metadata, and reference-only ingredient indexes.

## Main capabilities

- Search published label candidates without auto-selecting ambiguous names.
- Read original quantities, serving size, deterministic normalization, version, and source snapshot.
- Compare 2–5 labels only when ingredient identity, measurement object, unit, and basis are compatible.
- Inspect source records and rights scope.
- Retrieve reference-only ingredient evidence indexes.
- Aggregate label, references, and sources in one dossier.

## Data coverage and freshness

- Market: US only. Other markets return UNSUPPORTED_MARKET.
- Published label count: 93997.
- Last successful stored-snapshot sync: 2026-09-28T22:48:24.131Z.
- Runtime reads stored snapshots; it does not imply real-time upstream or inventory freshness.

## Sources and rights

Structured label records originate from NIH ODS DSLD. Source links identify provenance and do not imply endorsement. Packaging images, trademarks, third-party assets, and unapproved source bodies are excluded. NCCIH references, when mapped, are link-only unless separately approved.

## Limitations

No diagnosis, personalized dose, treatment, pregnancy/child safety conclusion, drug-combination guarantee, product ranking, purchase, or medical advice. Equal label quantity is not clinical equivalence. Missing quantity is not zero.
