Mass budget · computed
What Genestra Brands's declared salts weigh
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.

Gaps in the record for Genestra Brands
- 1 of 2 label does not name the magnesium salt in the filed record, so no compound mass can be computed for it.
- 2 of 2 labels have no US retail listing matched as of 2026-09-13. That is a matching gap on our side, not evidence of unavailability.

The metric
What EC100 measures
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.
