Magnesium lines as filed

SimplySupplements Magnesium 100 mg retains 1 magnesium-related rows in NIH DSLD 22271, including 1 rows selected for the primary serving, from label 2013-08-23, examined 2026-09-13.

The elemental amount comes from the selected magnesium line. A salt named under another nutrient does not make that nutrient's quantity an elemental magnesium value. Distinct unresolved primary amounts remain ambiguous; they are not added together.

Package arithmetic · observed inputs, computed totals

What the package works out to

SimplySupplements Magnesium 100 mg has no filed serving count for package arithmetic in NIH DSLD 22271, according to label 2013-08-23, calculated 2026-09-13.

Days = filed servings per container ÷ filed servings per day. If the label gives a frequency range, the largest frequency gives the shortest duration. Cost per serving = observed item price ÷ filed servings; cost per label-day multiplies this by the filed frequency. This follows the label's own instructions; it is package arithmetic, not intake advice.
