Supplement FDA Adverse Event 2014-2024 Decade Audit

A modeled 10-year audit of US dietary supplement adverse events, organized against the FDA CFSAN Adverse Event Reporting System (CAERS) framework, 2014-01-01 through 2024-12-31. The figures are analyzed aggregates calibrated against published CAERS-derived literature — directional estimates, not a live extract of raw CAERS records (see Data provenance below). Organized by 14 ingredient categories, severity tier, top reactions, and (where publicly attributable) brand and ingredient flags.

What's in it

Files: data.json, caers-supplement-adverse-events-by-category-2014-2024.csv, caers-supplement-adverse-events-trends-severity-ingredients-2014-2024.csv. Main table categories (14 rows): category, total_reports_2014_2024, serious_outcome_count, serious_outcome_pct, top_reactions, top_ingredients, top_brands_publicly_named, trend_2014_to_2024_pct_change, source_caers_url.

Data provenance (read before citing)

This dataset is MODELED, not extracted. The numeric values in the tables (per-category report counts, serious-outcome percentages, 2014→2024 trends) are analyzed aggregates calibrated against published CAERS-derived literature — e.g., Geller et al. (NEJM 2015) and FDA/CFSAN summary analyses — applied through the 14-category supplement taxonomy below. They are directional estimates, not exact counts extracted from raw FDA CAERS quarterly files.

  • Sourced (verifiable): the FDA CAERS system and the published peer-reviewed CAERS analyses the estimates are calibrated against; the FDA serious-outcome definitions (death / life-threatening / hospitalization / disability / congenital-anomaly / required-intervention); the 14-category taxonomy (vitamins, minerals, herbal/botanicals, weight-loss, sports/bodybuilding, immune, digestive/probiotic, sexual-health, sleep/relaxation, energy/stimulant, CBD/cannabinoid, hormones/precursors, multivitamins, MLM-distributed brands, other).
  • Modeled / estimated: every numeric value in the tables (category counts, severity %, trend %). Mixed-category products are counted toward each applicable category, so category totals sum above the unique-record total.
  • NOT a live extract: this is not a download of raw CAERS files. For the official raw quarterly CAERS data, see https://www.fda.gov/food/compliance-enforcement-food/cfsan-adverse-event-reporting-system-caers. Do not quote these figures as exact FDA record counts.

(This same provenance statement appears on the study page and in data.json. CAERS is voluntary and captures an FDA-estimated 1–10% of true events; reports do not establish causation.)
