Magnesium lines as filed

Country Life Magnesium Glycinate 400 mg Tangy Berry Flavor retains 1 magnesium-related rows in NIH DSLD 183706, including 1 rows selected for the primary serving, from label 2019-02-25, examined 2026-09-13.

Magnesium (Form: as Magnesium Glycinate)

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.

Percentile = 100 × the number of prices at or below this EC100 ÷ the number of observed prices in this salt, rounded to an integer. Ties receive the same percentile. The comparison includes this label; a high percentile means higher observed cost. Price is the dated item observation, excluding tax, shipping, coupons and subscriptions.

Package arithmetic · observed inputs, computed totals

What the package works out to

Country Life Magnesium Glycinate 400 mg Tangy Berry Flavor works out to 32 days per package at the label's own serving and filed frequency of 1 servings per day, according to label 2019-02-25, calculated 2026-09-13.

Price per day at the label's own serving$0.9372 · computed from price observed 2026-09-11

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

Country Life Magnesium Glycinate 400 mg Tangy Berry Flavor files 1 magnesium percent-daily-value entries in NIH DSLD 183706; 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.
