At powder density 0.6–0.8 g/mL, 238 mg of powder fits a size 0 capsule (holds about 545 mg).

The verdict uses the most favourable reading for the product — the smallest compound mass the label allows. It excludes the shell and other ingredients; their unreported masses are not added as guesses.

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.

Magnesium lines as filed

Solgar Potassium Magnesium Aspartate retains 1 magnesium-related rows in NIH DSLD 201597, including 1 rows selected for the primary serving, from label 2019-04-25, examined 2026-09-13.

Magnesium (Form: as Magnesium Aspartate)

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.

What the package works out to

Solgar Potassium Magnesium Aspartate has no filed serving count for package arithmetic in NIH DSLD 201597, according to label 2019-04-25, 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

Solgar Potassium Magnesium Aspartate files 1 magnesium percent-daily-value entries in NIH DSLD 201597; the check below applies the group-specific references in 21 CFR 101.9 to its 20 mg primary serving, calculated 2026-09-13.

Declared values and current-reference arithmetic
Group as filedDeclaredReferenceRecomputedDifference
Adults and children 4 or more years of age5%420 mg5%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

Solgar Potassium Magnesium Aspartate lists 5 other ingredients in NIH DSLD 201597, label dated 2019-04-25, 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.
