At powder density 0.6–0.8 g/mL, 455 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

BulkSupplements.com Magnesium Gluconate 500 mg retains 1 magnesium-related rows in NIH DSLD 294870, including 1 rows selected for the primary serving, from label 2023-07-18, examined 2026-09-13.

Filed amountServing orderFiled salt / notesCalculation role
80 mg1Salt not identified in this row as of 2026-09-13Selected 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

BulkSupplements.com Magnesium Gluconate 500 mg works out to 100 days per package at the label's own serving and filed frequency of 1 servings per day, according to label 2023-07-18, calculated 2026-09-13.

Servings per package100
Daily servings in the label instructions1
Days per package at the label's own serving100 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

BulkSupplements.com Magnesium Gluconate 500 mg files 1 magnesium percent-daily-value entries in NIH DSLD 294870; the check below applies the group-specific references in 21 CFR 101.9 to its 80 mg primary serving, calculated 2026-09-13.

Declared values and current-reference arithmetic
Group as filedDeclaredReferenceRecomputedDifference
Adults and children 4 or more years of age19%420 mg19%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.
