Share
Updated October 20, 2026

Compound weight is not elemental magnesium
The weight of a magnesium compound includes more than magnesium itself. Use the line labeled “Magnesium” on the Supplement Facts panel for a meaningful comparison. A larger front-label compound number does not necessarily mean more elemental magnesium.
Does one form automatically work better?
This label comparison does not establish that one form is superior for sleep, memory or another personal goal. Product names and bottle counts cannot establish clinical benefit. Choose a formula with your healthcare professional when individual needs or medication use are relevant.
Compare value fairly
Divide the live bottle price by its labeled number of servings. Compare servings as well as total magnesium per serving; capsule count alone can be misleading.
Can I take both?
Do not add them together just because the forms differ. Count magnesium from all supplements and medicines, and review the combined intake with a healthcare professional.
