KAL files 18 on-market magnesium labels, and 2 of the 3 audited declare more of the named salt than a standard capsule can hold.
Mass budget · computed
A Supplement Facts panel declares the element; the salt carrying it is heavier. Dividing each label's declared magnesium by its salt's elemental fraction gives the powder mass the serving must contain — and whether that fits a capsule.

17 published excipient facets occur across 18 labels from KAL in the NIH DSLD records, counted 2026-09-13.
The FDA adverse event reporting system (CAERS) holds 30 reports naming KAL as of 2026-09-13. This is a count of submitted reports across all the firm's products; it is not an incidence rate and implies no causation.
The metric
EC100 = container price ÷ (elemental mg per serving × servings per container ÷ 100)
It normalizes the declared elemental amount to a 100 mg unit. It does not score ingredients, quality, or outcomes.
