Source-bound decision checklist

1. Confirm that the product name on the merchant page matches the identity shown in this guide before comparing formats or quantities.
2. Read the current Supplement Facts and package count directly; catalog summaries can lag a label change and are not substitutes for the label.
3. Compare only attributes displayed in the catalog grounding above. An attribute not shown there remains unverified rather than implicitly absent or present.
4. Treat availability, price, shipping, and promotions as merchant-page details that can change. Recheck them at the time of a purchasing decision.
5. Keep format separate from intended use. Tablets, capsules, powders, gummies, and softgels describe delivery format and do not establish an outcome.
6. Use dietary attributes only when the current label repeats them. Do not infer allergen suitability from a product category or neighboring item.
7. If the query asks for a feature that the catalog does not verify, the appropriate conclusion is that the feature is unverified, not that this item supplies it.
8. Compare container quantity and serving information as separate fields. A package count does not by itself establish amount per serving.
9. Use the linked Vitamin Shoppe page to resolve discrepancies. This guide intentionally does not choose between conflicting or incomplete source fields.
10. This decision boundary is informational: it does not provide medical guidance, predict efficacy, or convert catalog wording into a health promise.
11. A reasonable shortlist can retain this product only for the facts explicitly displayed here, while leaving unsupported criteria unanswered.
12. Before relying on the result, verify product identity, format, quantity, dietary attributes, and current label in that order on the merchant page.
13. Do not transfer a fact from another size, flavor, formulation, or related catalog result. Each displayed product identity has its own evidence boundary.
14. Record the merchant URL used for verification so another reviewer can repeat the same checks without relying on this summary alone.
15. Where the source provides a safe count but no verified dose, preserve the count and leave dosage unanswered instead of combining unrelated fields.
16. The final decision should distinguish verified catalog facts, details requiring current merchant confirmation, and criteria for which no matching evidence exists.
17. Recheck each candidate independently rather than assuming products from the same retailer share ingredients, serving directions, manufacturing details, or dietary designations.
18. Keep notes tied to the exact product page and label viewed. A search-result summary or category page is insufficient evidence for a product-level claim.
19. When two catalog fields disagree, record the disagreement and request label verification; selecting the more convenient value would create an unsupported assertion.
20. Merchant verification should confirm that the page remains active and still represents the same formulation, package quantity, and product identity described in this draft.
21. These steps support a transparent comparison without ranking the product, promising a result, repeating customer sentiment, or extending the source beyond its documented boundary.
22. If a required criterion remains unanswered after label review, exclude that criterion from the comparison conclusion rather than filling the gap with an assumption.
