What Nature's Way'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 Nature's Way uses
| Salt | Labels | Elemental fraction | Compound needed per 100 mg |

What Nature's Way puts in the capsule besides magnesium
- 2 of 5 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.
- 1 label uses a cellulose-based shell.

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

FDA assigns 3 recall classes by the assessed hazard, using the FDA classification definitions, checked 2026-09-13:
- Class I: Exposure to or use of the violating product carries a reasonable probability of serious harm to health or death.
- Class II: Exposure or use may produce temporary or medically reversible harm; the probability of serious harm is remote.
- Class III: Adverse health consequences from exposure or use are unlikely.
The FDA adverse event reporting system (CAERS) holds 100 reports naming Nature's Way 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.
