Data Sources & Provenance

• Primary: on-package labels, manufacturer sites, official retailers
• Secondary: brand documentation and regulatory disclosures
• User submissions: queued for editorial review before publication
• Provenance: each entry tracks source type, capture date, and reviewer

Coverage & Update Cadence

• Coverage: 189k+ products across 6k+ brands
• Refresh: continuous ingestion plus regular editorial sweeps
• We strive to review brand-reported changes quickly and prioritize user submissions within a few days.

Quality Assurance

• Automated checks: label completeness, unit/serving validation, ingredient normalization
• Manual review: form/elemental mapping, variant matching (size/count/flavor), reasonableness checks
• Acceptance: no critical conflicts, taxonomy match, unit consistency
• Change log: material updates flagged in the record's history

Ingredient Parsing & Nutrient Math

• Forms: map labeled forms (e.g., magnesium glycinate) to elemental amounts where provided
• Units: normalize mg/µg/IU; round to label-appropriate precision
• Daily totals: computed per user servings and aggregated across products/stacks
• Proprietary blends: recorded as declared; amounts shown only if disclosed

Known Limitations

• Packaging changes and regional variants may lag before review
• Proprietary blends may not disclose all ingredient amounts
• Some forms or claims may be brand-specific and not standardized
• Region-specific formulas or claims may differ from US labels
