Magnesium lines as filed

Natural Nutra Chelated Magnesium 250 mg retains 1 magnesium-related rows in NIH DSLD 246886, including 1 rows selected for the primary serving, from label 2021-04-22, examined 2026-09-13.

Selected primary serving

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.

What the package works out to

Natural Nutra Chelated Magnesium 250 mg works out to 45–90 days per package at the label's own serving and filed frequency of 1–2 servings per day, according to label 2021-04-22, calculated 2026-09-13.

Arithmetic using the label's own serving, not intake advice
Net contents as filed90 Tablet(s)
Discrete units in the package90
Serving size as filed1 Tablet(s)
Units per serving1
Servings per package90
Daily servings in the label instructions1–2
Days per package at the label's own serving45–90 days

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.

A same-salt reference for this package

At the median cost per 100 mg observed across 14 oxide labels ($0.0571), a package of this size (22,500 mg elemental in Natural Nutra Chelated Magnesium 250 mg) would correspond to $12.84, using observations from 2026-08-10 to 2026-09-11, calculated 2026-09-13. This is a benchmark, not a retailer quote.

The median is the middle sorted observation, or the average of the two middle observations for an even group. Each label contributes one observation. This value is neither an offer nor an estimate of a specific retailer's current price.

Percent daily value · observed and computed

The label's percent daily value, recomputed

Natural Nutra Chelated Magnesium 250 mg files 1 magnesium percent-daily-value entries in NIH DSLD 246886; the check below applies the group-specific references in 21 CFR 101.9 to its 250 mg primary serving, calculated 2026-09-13.

Declared values and current-reference arithmetic
Group as filedDeclaredReferenceRecomputedDifference
Adults and children 4 or more years of age63%420 mg60%3 percentage points

Percent daily value = declared elemental mg ÷ the group's reference mg × 100, rounded to an integer. The adult and age-four-plus reference is 420 mg. Historical labels can use earlier references; a difference does not establish a filing error. Full-record entries may cover multiple serving sizes, so this table identifies the primary-serving basis explicitly. Group references and interpretation.
