What Freeda'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.

| Salt | Labels | Elemental fraction | Compound needed per 100 mg |
|---|---|---|---|
| citrate | 3 | 11.3–16.16% | 619–885 mg |

What Freeda puts in the capsule besides magnesium
- 2 of 6 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.
- 5 labels use a cellulose-based shell.

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.
