What Nature's Life puts in the capsule besides magnesium

- 1 label uses a gelatin 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.
