Rainbow Light Magnesium Calcium+

Rainbow Light Magnesium Calcium+ declares 321 mg of elemental magnesium from an amino acid chelate — a class of compounds, not a defined substance, so no elemental fraction exists and the salt mass cannot be computed; NIH DSLD 245930, label dated 2021-03-25, calculation 2026-09-13.

Magnesium lines as filed

Rainbow Light Magnesium Calcium+ retains 2 magnesium-related rows in NIH DSLD 245930, including 1 rows selected for the primary serving, from label 2021-03-25, examined 2026-09-13.

Filed amounts, salt names and serving order

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

Rainbow Light Magnesium Calcium+ works out to 90 days per package at the label's own serving and filed frequency of 1 servings per day, according to label 2021-03-25, calculated 2026-09-13.

Servings per package90
Daily servings in the label instructions1
Days per package at the label's own serving90 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

Rainbow Light Magnesium Calcium+ files 1 magnesium percent-daily-value entries in NIH DSLD 245930; the check below applies the group-specific references in 21 CFR 101.9 to its 321 mg primary serving, calculated 2026-09-13.

Declared values and current-reference arithmetic
Group as filedDeclaredReferenceRecomputedDifference
Adults and children 4 or more years of age76%420 mg76%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.
