Why this one is different

This tool doesn't sell magnesium, so the comparison has no reason to lean toward any one brand or form. No product links, no shop buttons, no catalog hiding behind a quiz.

Magnesium is a high-interest supplement category, and interest in sleep-related use is rising even as some individual forms cool off. Plenty of quizzes exist. Most of them route you to four products the site happens to stock.

What you get instead: a safety gate that runs before any matching, goal-based scoring you can trace back to your own answers, and independent label math on elemental magnesium.

Safety check Runs before any matching

How this works

Safety runs first. If a caution applies, matching stops there and no form or dose is suggested. The label checker still works.

The magnesium number on a Supplement Facts panel is elemental magnesium, not the weight of the whole compound. Magnesium citrate powder, for instance, is mostly citrate by weight. Use the elemental number for your daily total.

Magnesium form

Elemental magnesium per serving (mg)

Servings per day

Daily supplemental total

Enter your label numbers

elemental mg per serving × servings per day = total supplemental magnesium per day

Pick a form and the tool also estimates how much total compound weight that elemental amount represents.

For U.S. adults, NIH lists recommended magnesium intakes of roughly 310 to 420 mg per day depending on age and sex. The 350 mg upper limit applies to magnesium from supplements and medications, not magnesium naturally present in food.

Types, trade-offs, and what people actually mean

No form wins universally. What changes is the goal it suits, how it treats your stomach, what it costs, and how thin the evidence gets once you leave general supplementation behind.

Elemental-magnesium percentages are approximate and vary with hydration state and manufacturing. Evidence labels are deliberately conservative: for several popular uses the honest answer is that research is still developing.
