Magnesium lines as filed

Thompson Magnesium 100 mg retains 1 magnesium-related rows in NIH DSLD 36326, including 1 rows selected for the primary serving, from label 2014-08-26, examined 2026-09-13.

Filed amounts, salt names and serving order
Filed amountServing orderFiled salt / notesCalculation role
400 mg1gluconate, oxide

Magnesium (Form: as Magnesium Oxide, and Magnesium Gluconate)

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

Thompson Magnesium 100 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 2014-08-26, calculated 2026-09-13.

Arithmetic using the label's own serving, not intake advice
Net contents as filed120 Tablet(s)
Discrete units in the package120
Serving size as filed4 Tablet(s)
Units per serving4
Servings per package30
Daily servings in the label instructions1
Days per package at the label's own serving30 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

Thompson Magnesium 100 mg files 1 magnesium percent-daily-value entries in NIH DSLD 36326; the check below applies the group-specific references in 21 CFR 101.9 to its 400 mg primary serving, calculated 2026-09-13.

Declared values and current-reference arithmetic
Group as filedDeclaredReferenceRecomputedDifference
Adults and children 4 or more years of age100%420 mg95%5 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.
