Supplement decision tools
Magnesium Form Selector
Compare magnesium forms with your goal, stomach tolerance and health context in mind. Start with the elemental amount, not a claim that one form is best for everyone.
Quick answer
The selector points you to a relevant comparison, not a diagnosis or product ranking. If you have a kidney, medicine, pregnancy or other medical concern, check that first. No magnesium form is an established universal winner for sleep.
Find the next useful comparison. The selector does not name a best product or diagnose magnesium deficiency.

Why form matters
Compare elemental amount, form, serving size and tolerance. NIH ODS explains magnesium forms, labels and medication cautions. Absorption differences do not automatically establish better health outcomes.
How this tool works
Answer the health-context question first, then choose the topic and your experience with loose stools. A caution takes priority over form guidance. Otherwise the result explains what to compare and links to the relevant guide.
Sleep example: choosing sleep does not produce a glycinate recommendation. NCCIH describes limited and conflicting magnesium sleep findings.
For constipation, a magnesium laxative has a different purpose and directions from an everyday supplement. The selector cannot choose treatment or a laxative dose.
