NFH magnesium labels
NFH files 3 on-market magnesium labels using 2 different salts, with a median of 150 mg elemental magnesium per serving.
Mass budget · computed
What NFH'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.
| Capsule labels audited | 3 |
|---|---|
| Fit a size 0 or 00 capsule | 0 |
| Require the largest standard size, 000 | 3 |
| Exceed every standard capsule | 0 |

Which magnesium salts NFH uses
| Salt | Labels | Elemental fraction | Compound needed per 100 mg |
|---|---|---|---|
| glycinate | 2 | 11.83–14.1% | 709–845 mg |
| citrate | 1 | 11.3–16.16% | 619–885 mg |
Composition across the portfolio · as filed
What NFH puts in the capsule besides magnesium
- 3 of 3 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.

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.
