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.

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.
