Swolverine magnesium labels
Swolverine files 1 on-market magnesium label, and 1 of the 1 audited declares more of the named salt than a standard capsule can hold.
Mass budget · computed
What Swolverine'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 | 1 |
|---|---|
| Fit a size 0 or 00 capsule | 0 |
| Require the largest standard size, 000 | 0 |
| Exceed every standard capsule | 1 |

What Swolverine puts in the capsule besides magnesium
- 1 of 1 label lists 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.
- 1 label uses 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.
