Magnesium lines as filed
SuperSmart Magnesium Malate 2400 mg retains 1 magnesium-related rows in NIH DSLD 315600, including 1 rows selected for the primary serving, from label 2024-08-22, examined 2026-09-13.
| Filed amount | Serving order | Filed salt / notes | Calculation role |
|---|---|---|---|
| 480 mg | 1 | Salt not identified in this row as of 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.
Package arithmetic · observed inputs, computed totals
What the package works out to
SuperSmart Magnesium Malate 2400 mg works out to 40 days per package at the label's own serving and filed frequency of 1 servings per day, according to label 2024-08-22, calculated 2026-09-13.
| Net contents as filed | 120 Tablet(s) |
|---|---|
| Discrete units in the package | 120 |
| Serving size as filed | 1–3 Tablet(s) |
| Units per serving | 1–3 |
| Servings per package | 40 |
| Daily servings in the label instructions | 1 |
| Days per package at the label's own serving | 40 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.
Benchmark · 9 observed prices in malate
A same-salt reference for this package
At the median cost per 100 mg observed across 9 malate labels ($0.1142), a package of this size (19,200 mg elemental in SuperSmart Magnesium Malate 2400 mg) would correspond to $21.93, using observations from 2026-08-10 to 2026-09-11, calculated 2026-09-13. This is a benchmark, not a retailer quote.
| Salt and number of observations | Magnesium malate · n = 9 |
|---|---|
| Median observed cost per 100 mg | $0.1142 |
| Filed elemental magnesium per package | 19,200 mg |
| Benchmark package equivalent | $21.93 = median EC100 × package elemental mg ÷ 100 |
| Evidence tier | benchmark · calculated 2026-09-13 |
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
SuperSmart Magnesium Malate 2400 mg files 1 magnesium percent-daily-value entries in NIH DSLD 315600; the check below applies the group-specific references in 21 CFR 101.9 to its 480 mg primary serving, calculated 2026-09-13.
| Group as filed | Declared | Reference | Recomputed | Difference |
|---|---|---|---|---|
| Adults and children 4 or more years of age | 127% | 420 mg | 114% | 13 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.
