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.

Observed means a value transcribed from a label or price observation. Computed means arithmetic or normalization of those inputs. Modelled means the result depends on a stated physical assumption, including capsule capacity. Evidence tiers and their limits.

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 amount | Serving order | Filed salt / notes | Calculation role |
|---|---|---|---|
| 67 mg | 1 | ascorbate Vitamin C (Form: as Magnesium Ascorbate) | Other nutrient or serving row; excluded from primary amount |
| 321 mg | 1 | ascorbate, aspartate, oxide Magnesium (Form: as Magnesium Oxide, Magnesium Chelate, Magnesium Ascorbate, 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.
Package arithmetic · observed inputs, computed totals
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.
| Net contents as filed | 90 Tablet(s) |
|---|---|
| Discrete units in the package | 90 |
| Serving size as filed | 1 Tablet(s) |
| Units per serving | 1 |
| Servings per package | 90 |
| Daily servings in the label instructions | 1 |
| Days per package at the label's own serving | 90 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.
| Group as filed | Declared | Reference | Recomputed | Difference |
|---|---|---|---|---|
| Adults and children 4 or more years of age | 76% | 420 mg | 76% | 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.
