Magnesium lines as filed

Complete H2O Minerals Magnesium Concentrate retains 1 magnesium-related rows in NIH DSLD 252064, including 1 rows selected for the primary serving, from label 2021-07-27, examined 2026-09-13.

Filed amounts, salt names and serving order
Filed amountServing orderFiled salt / notesCalculation role
18 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.

Package arithmetic · observed inputs, computed totals

What the package works out to

Complete H2O Minerals Magnesium Concentrate files 32 servings per package, with no complete daily-frequency range for computing days, according to label 2021-07-27, calculated 2026-09-13.

Arithmetic using the label's own serving, not intake advice
Net contents as filed16 Oz(s); 1 Pint(s); 473 mL
Serving size as filed15 mL (1 Tbsp.)
Servings per package32
Daily servings in the label instructionsComplete daily-frequency range not filed as of 2026-09-13
Days per package at the label's own servingDays not computable from filed frequency and serving count as of 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

Complete H2O Minerals Magnesium Concentrate files 1 magnesium percent-daily-value entries in NIH DSLD 252064; the check below applies the group-specific references in 21 CFR 101.9 to its 18 mg primary serving, calculated 2026-09-13.

Declared values and current-reference arithmetic
Group as filedDeclaredReferenceRecomputedDifference
Adults and children 4 or more years of age20%420 mg4%16 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.
