Cross-brand record matches

Matching filed formulations

11 matching filed formulation clusters connect 27 magnesium labels across brands in NIH DSLD snapshot 2026-08-10, fingerprinted 2026-09-13; each cluster contains at least 4 distinct excipients and 2 brands.

The fingerprint hashes the sorted lowercase excipient list, shell classification, units per serving and elemental mg per unit rounded to 5 mg. A matching filed formulation indicates similarity between records; it does not prove a common manufacturer. Salt identity and excipient quantities are outside this fingerprint.

Read a cluster from filed inputs to prices

27 labels enter the 11 groups in this table, using NIH DSLD snapshot 2026-08-10 and fingerprints calculated 2026-09-13; the cluster page retains each input and the original label identifiers.

Start with the ingredient list and serving structure to identify the match. The product links expose the original serving statement, elemental amount and source record. Brand links open the surrounding portfolio, including other formulations and any dated FDA name matches. Ingredient links open only published facets meeting the 10-label threshold.

Brand counts consolidate known spelling variants, while the linked brand names retain their original filed spelling. The fingerprint preserves ingredient wording; the linked excipient facets normalize specified synonyms. Thus a facet membership alone does not establish a formulation match.

Price intervals use published EC100 observations inside each resolved salt. A single observation has equal minimum and maximum but no multi-observation spread ratio. An unresolved salt cannot enter a same-salt price interval. Each cluster's price table shows observation dates and match status; the methodology defines these evidence categories.
