What the declared salt would weigh
Trace Minerals Magnesium Tablets 300 mg declares 300 mg of elemental magnesium per serving in NIH DSLD 322518, requiring 1,175.09–2,508.36 mg of magnesium chloride under the salt model calculated 2026-09-13.
| Step | Value | Evidence |
|---|---|---|
| Declared elemental magnesium | 300 mg per serving | observed · label 2025-03-25 |
| Resolved salt | Magnesium chloride · full-record | computed · name resolved from filed text |
| Reference formula | MgCl₂; 95.21 g/mol | computed · chemical reference |
| Elemental fraction | 11.96–25.53% by mass | computed |
| Why the fraction is a range | anhydrous 25.5%, hexahydrate 12.0% | modelled · hydrate not specified |
| Compound mass per serving | 1,175.09–2,508.36 mg = 300 mg ÷ elemental fraction | computed |
| Compound mass per discrete unit | 587.54–1,254.18 mg | computed |
Size 0 holds about 545 mg, size 00 about 730 mg, and size 000 about 1,100 mg at powder density 0.6–0.8 g/mL. These are model inputs, not measurements of this product's capsule. Read the mass-budget method.

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
Trace Minerals Magnesium Tablets 300 mg retains 1 magnesium-related rows in NIH DSLD 322518, including 1 rows selected for the primary serving, from label 2025-03-25, examined 2026-09-13.
| Filed amount | Serving order | Filed salt / notes | Calculation role |
|---|---|---|---|
| 300 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
Trace Minerals Magnesium Tablets 300 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 2025-03-25, calculated 2026-09-13.
| Net contents as filed | 60 Tablet(s) |
|---|---|
| Discrete units in the package | 60 |
| Serving size as filed | 2 Tablet(s) |
| Units per serving | 2 |
| 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
Trace Minerals Magnesium Tablets 300 mg files 1 magnesium percent-daily-value entries in NIH DSLD 322518; the check below applies the group-specific references in 21 CFR 101.9 to its 300 mg primary serving, calculated 2026-09-13.
| Group as filed | Declared | Reference | Recomputed | Difference |
|---|---|---|---|---|
| Adults and children 4 or more years of age | 71% | 420 mg | 71% | 0 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.
