What NHC Natural Healthy Concepts'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.

What NHC Natural Healthy Concepts puts in the capsule besides magnesium
- 2 of 4 labels list magnesium stearate. Stearate is 4.1% magnesium by mass and that magnesium is not on the Supplement Facts line; the amount of stearate is not declared, so it cannot be quantified.
- 3 labels use a cellulose-based shell.

Gaps in the record for NHC Natural Healthy Concepts
- 3 of 4 labels do not name the magnesium salt in the filed record, so no compound mass can be computed for them.
- 4 of 4 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.
