Mass budget · computed
What Wonder Laboratories'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.

| Fit a size 0 or 00 capsule | 4 |
| Require the largest standard size, 000 | 0 |

Which magnesium salts Wonder Laboratories uses
| Salt | Labels | Elemental fraction | Compound needed per 100 mg |
|---|---|---|---|
| aspartate | 4 | 7.49–15.64% | 639–1,335 mg |
| carbonate | 2 | 24.78–28.83% | 347–404 mg |
Composition across the portfolio · as filed
What Wonder Laboratories puts in the capsule besides magnesium
- 9 of 9 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.
- 4 labels use a gelatin shell.
- 5 labels use a cellulose-based shell.

Gaps in the record for Wonder Laboratories
- 3 of 9 labels do not name the magnesium salt in the filed record, so no compound mass can be computed for them.
- 9 of 9 labels have no US retail listing matched as of 2026-11-02. 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.
