Methodology

Methodology, version 1.0

How an entry gets made, what the status words mean, and what Dosescope deliberately does not do.

Updated Sep 18, 2025

What is recorded

For each product, one label revision at a time: serving size and directions as printed, every line of the Supplement Facts panel with its unit, declared form and percent Daily Value, other ingredients, quoted claims, warnings, sources, and single-day price observations.

Sources, in order of preference

  • A photograph of the physical label, with lot or batch number where legible.
  • The brand’s own website.
  • A retailer listing.
  • An official database entry.

When sources disagree, the row is marked “Sources conflict” and the entry is flagged for re-check. No number is shown until it is settled.

Status words

  • Listed: the amount as printed on the label.
  • Not listed on label: the panel does not mention this nutrient. This is not a measured zero.
  • Not obtained yet: a readable source for this line is still being secured.
  • Sources conflict: two sources disagree.

Review and publication

An entry is published only after a second reading against its sources, a rights check, and at least one ingredient row. Each product has at most one current label; earlier revisions stay reachable, marked as earlier labels and excluded from search engines. A withdrawn entry shows only its withdrawal note.

Comparisons

Only current labels in the same category can be compared, two or three at a time. Amounts are per serving as printed and are never scaled to a common serving. The “differences only” view hides identical rows but never rows with missing, unconfirmed or conflicting data.

What Dosescope does not do

  • It does not test products in a laboratory.
  • It does not score, rank or recommend.
  • It does not evaluate label claims or give medical advice.

Corrections

Published data is never silently edited. Corrections are dated on the entry and listed in the changelog.
