DC magnesium labels
DC files 12 on-market magnesium labels, and 2 of the 2 audited declare more of the named salt than a standard capsule can hold.

What DC'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.

Which magnesium salts DC uses
| Salt | Labels | Elemental fraction | Compound needed per 100 mg |
|---|---|---|---|
| oxide | 5 | 60.32% | 166 mg |
| aspartate | 2 | 8.42% | 1,188 mg |
Composition across the portfolio · as filed
What DC puts in the capsule besides magnesium
- 12 of 12 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.
- 2 labels use a gelatin shell.
- 10 labels use a cellulose-based shell.

Gaps in the record for DC
- 5 of 12 labels do not name the magnesium salt in the filed record, so no compound mass can be computed for them.
- 10 of 12 labels have no US retail listing matched as of 2026-09-13. That is a matching gap on our side, not evidence of unavailability.

- 135 mg per unit, rounded to 5 mg; 6 filed ingredients: 1 labels from this brand, 3 labels and 2 brands in the cluster.
The FDA adverse event reporting system (CAERS) holds 3 reports naming DC as of 2026-09-13. This is a count of submitted reports across all the firm's products; it is not an incidence rate and implies no causation.
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.
