up&up Magnesium 250 mg

Label facts and derived measurements

The numbers for this label

up&up Magnesium 250 mg has 11 published fields below, traced to NIH DSLD 19971 and the 2026-08-10 registry snapshot, with calculations dated 2026-09-13.

Observed means a value transcribed from a label or price observation. Computed means arithmetic or normalization of those inputs. Modelled means the result depends on a stated physical assumption, including capsule capacity. Evidence tiers and their limits.

Source transcription · observed

Magnesium lines as filed

up&up Magnesium 250 mg retains 1 magnesium-related rows in NIH DSLD 19971, including 1 rows selected for the primary serving, from label 2013-03-25, 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

up&up Magnesium 250 mg has no filed serving count for package arithmetic in NIH DSLD 19971, according to label 2013-03-25, 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.

Percent daily value · observed and computed

The label's percent daily value, recomputed

up&up Magnesium 250 mg files 1 magnesium percent-daily-value entries in NIH DSLD 19971; the check below applies the group-specific references in 21 CFR 101.9 to its 250 mg primary serving, calculated 2026-09-13.

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.

Composition · observed

Other ingredients in the filed record

up&up Magnesium 250 mg lists 9 other ingredients in NIH DSLD 19971, label dated 2013-03-25, examined 2026-09-13.

Capsule material: vegetarian. The material classification follows the filed ingredient names; it is not a test of the shell.

This label lists magnesium stearate, whose reference elemental fraction is 4.1% by mass. No stearate quantity is available in this record as of 2026-09-13, so its magnesium contribution cannot be quantified or added to the Supplement Facts magnesium total.

Label declarations · observed

Target groups as filed

up&up Magnesium 250 mg has 2 target-group entries in NIH DSLD 19971, label dated 2013-03-25, examined 2026-09-13.

Provenance · observed

Registry record, versions and scanned label

up&up Magnesium 250 mg is identified by 1 NIH DSLD record, 19971, according to the retained record examined 2026-09-13; the label date is 2013-03-25.

The barcode is retained as an identifier, not as proof of a retail match. A registry version count records the number held; it does not reveal what changed. The label date, registry snapshot and price-observation date describe different events.

Gaps in this record

What is not available for this label

up&up Magnesium 250 mg has 3 unresolved data gaps in the retained NIH DSLD and price records as of 2026-09-13.

An unmatched retail price describes our matching coverage. It does not establish that a product is unavailable. The elemental cost calculator can apply the same EC100 formula to a price you supply.
