What Geri-Care puts in the capsule besides magnesium
- 2 of 2 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 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.
