Magnesium ascorbate: 7 labels, magnesium per serving as filed
7 labels name magnesium ascorbate. Magnesium per serving is printed as filed. No single elemental fraction is defined for this name.
This site's chemistry model has no single formula for magnesium ascorbate as filed on labels, so no elemental fraction, compound mass or capsule count is computed. 7 on-market labels name magnesium ascorbate; median filed amount 321 mg elemental magnesium per serving; 5 of them blend it with other forms. No US retail price is matched as of 2026-11-02.

How much elemental magnesium is actually in 100, 200 or 400 mg of ascorbate?
This site's chemistry model has no single formula for magnesium ascorbate as filed on labels, so compound mass for 100, 200 or 400 mg elemental magnesium is not computed as of 2026-08-10.
measuredThe chemistry model has no formula for this filed salt, so a fraction is not computed.

Estimated salt mass versus assumed capsule capacity
No capsule label names magnesium ascorbate alone as of 2026-08-10, so no capsule verdict is counted. The 7 labels naming this form remain in the full registry.
computed with assumptionNo capsule label naming ascorbate alone can be checked against capsule sizes in this snapshot.
| Mass budget verdict | Labels |
|---|---|
| Capsule labels naming this salt alone | None as of 2026-08-10 |
A size 00 capsule holds about 730 mg of powder at powder density 0.8 g/mL, the top of the usual 0.6–0.8 range; a size 000 about 1,100 mg.
