Methodology

A "formula" is the sorted set of (compound, form, rounded elemental amount) tuples on a label plus its serving size. Products sharing an identical formula across at least two distinct brands form an exact-twin cluster — evidence of private-label / white-label manufacturing rather than a distinct formulation. The near-twin pass relaxes the match to compound+form only, ignoring declared amounts.

Every cluster with 25+ products

298 clusters are large enough to list here; the thousands of smaller ones are counted in the totals above but not given their own indexed page.
