The numbers for this label
Thompson Magnesium 100 mg has 11 published fields below, traced to NIH DSLD 36326 and the 2026-08-10 registry snapshot, with calculations dated 2026-09-13.
| Field | Value | Evidence tier |
|---|---|---|
| NIH DSLD identifier | 36326 | observed |
| Resolved salt | Single salt unresolved as of 2026-09-13 | computed |

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
Thompson Magnesium 100 mg retains 1 magnesium-related rows in NIH DSLD 36326, including 1 rows selected for the primary serving, from label 2014-08-26, examined 2026-09-13.
| Filed amount | Serving order | Filed salt / notes | Calculation role |
|---|---|---|---|
| 400 mg | 1 | gluconate, oxide Magnesium (Form: as Magnesium Oxide, and Magnesium Gluconate) | 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
Thompson Magnesium 100 mg works out to 30 days per package at the label's own serving and filed frequency of 1 servings per day, according to label 2014-08-26, calculated 2026-09-13.
| Net contents as filed | 120 Tablet(s) |
|---|---|
| Discrete units in the package | 120 |
| Serving size as filed | 4 Tablet(s) |
| Units per serving | 4 |
| Servings per package | 30 |
| Daily servings in the label instructions | 1 |
| Days per package at the label's own serving | 30 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.
Percent daily value · observed and computed
The label's percent daily value, recomputed
Thompson Magnesium 100 mg files 1 magnesium percent-daily-value entries in NIH DSLD 36326; the check below applies the group-specific references in 21 CFR 101.9 to its 400 mg primary serving, calculated 2026-09-13.
| Group as filed | Declared | Reference | Recomputed | Difference |
|---|---|---|---|---|
| Adults and children 4 or more years of age | 100% | 420 mg | 95% | 5 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.
