: Version 3: every label amount, set against every product
Rebuilt the site on the full NIH Dietary Supplement Label Database download (version 9.4.0, January 2026). Product pages had said the database gave no amounts; they now show every amount on the label, set against all products listing the same ingredient, the FDA Daily Value and the adult upper limit. Labels are grouped into one page per product name and brand (former duplicate addresses redirect to it), ingredients and their forms are grouped across spellings, and ten analyses with downloadable data were added. Former research and ranking pages redirect to the page answering the same question.
: Brand name deduplication
Merged product brand names that differed only by letter case or punctuation into a single canonical brand, with 301 redirects from the former slugs. No products were dropped in the merge.
: Release-history tracking added
Began retaining source-observed DSLD data snapshots (product and ingredient counts per release) so future comparisons against prior releases are honest and traceable.
: Ingredient aggregate integrity fix
Repaired ingredient-page aggregates, rankings, and category counts that had been inflated by product rows excluded from the canonical product population.
: Duplicate product listings flagged
DSLD periodically re-submits the same product across multiple label revisions, producing near-duplicate entries under the same name and brand. Flagged the non-canonical duplicates (38% of the catalog at the time) as noindex while keeping them served, so search engines see one canonical page per product.
: Initial data build completed
The first full ETL run populated the portal database from the FDA/NIH Dietary Supplement Label Database (DSLD).
