What Adaptogen Research'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 Adaptogen Research uses
| Salt | Labels | Elemental fraction | Compound needed per 100 mg |
|---|---|---|---|
| citrate | 1 | 11.3–16.16% | 619–885 mg |
| malate | 1 | 13.2–15.54% | 644–758 mg |
| aspartate | 1 | 8.42% | 1,188 mg |
Composition across the portfolio · as filed
What Adaptogen Research puts in the capsule besides magnesium
- 1 of 5 label lists 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.
- 5 labels use a cellulose-based shell.

Gaps in the record for Adaptogen Research
- 2 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.

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.
