2026-09-13 · Overnight expansion and connected records

The overnight release contains 16 studies and 74 published price observations as of 2026-09-13, alongside new pages derived from the retained source records.

• Methodology and the dataset expose evidence tiers, calculation inputs and dated gaps.
• Excipient facets, filed declarations and capsule shell groups connect source composition fields to their matching labels.
• Formulation clusters compare filed ingredient lists and serving structures across brands; price spreads stay within a single salt.
• Salt pairs show compound mass at equal elemental amounts with hydration intervals.
• The FDA recall register preserves recalling-firm names, product descriptions and source records.
• Food vs supplement compares masses containing 100 mg elemental magnesium.
• 16 absorption studies retain their measured endpoints and populations; 74 published prices retain observation dates and match status.
• Products and brands now link their filed ingredients, declarations and shared formulations; salt pages link their comparisons. Collection entries and breadcrumbs connect these pages to the magnesium hub.

2026-09-11 · Chemistry, measured absorption and prices

The 2026-09-11 revision organized 3 kinds of evidence around each label: salt chemistry, published absorption measurements and dated retail observations.

Salt pages expose elemental fractions and compound mass, the capsule audit shows mass against capacity, and study records attach outcomes to the experiments that measured them. Product pages retain the source of the assigned salt and the basis of each price match.

2026-09-10 · Publication scope narrowed

The 2026-09-10 revision introduced 3 publication tiers: priced, derived and registry-only, separating pages with an observed price or computed quantity from simple registry transcriptions.

Registry-only records remained accessible while their indexing was restricted. Subsequent work added label-specific arithmetic and dated statements of missing information, and reopened those records for indexing. The current editorial policy and methodology describe the published evidence.
