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.

Magnesium lines as filed
Swanson Albion Magnesium & Calcium retains 1 magnesium-related rows in NIH DSLD 308453, including 1 rows selected for the primary serving, from label 2024-12-21, examined 2026-09-13.
| Filed amount | Serving order | Filed salt / notes | Calculation role |
|---|---|---|---|
| 133 mg | 1 | Salt not identified in this row as of 2026-09-13 TRAACS, Buffered | 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
Swanson Albion Magnesium & Calcium works out to 30 days per package at the label's own serving and filed frequency of 3 servings per day, according to label 2024-12-21, calculated 2026-09-13.
| Net contents as filed | 90 Veggie Capsule(s) |
|---|---|
| Discrete units in the package | 90 |
| Serving size as filed | 1 Veggie Capsule(s) |
| Units per serving | 1 |
| Servings per package | 90 |
| Daily servings in the label instructions | 3 |
| 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
Swanson Albion Magnesium & Calcium files 1 magnesium percent-daily-value entries in NIH DSLD 308453; the check below applies the group-specific references in 21 CFR 101.9 to its 133 mg primary serving, calculated 2026-09-13.
| Group as filed | Declared | Reference | Recomputed | Difference |
|---|---|---|---|---|
| Adults and children 4 or more years of age | 32% | 420 mg | 32% | 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.

Other ingredients in the filed record
Swanson Albion Magnesium & Calcium lists 7 other ingredients in NIH DSLD 308453, label dated 2024-12-21, examined 2026-09-13.
| Entry | Ingredient |
|---|---|
| 1 | Hypromellose |
| 2 | Magnesium Oxide |
| 3 | Citric Acid |
| 4 | Maltodextrin |
| 5 | Silica |
| 6 | Rice Flour |
| 7 | Magnesium Stearate |
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.
