Magnesium lines as filed

Pure Encapsulations Magnesium EasySticks Natural Blueberry flavor retains 1 magnesium-related rows in NIH DSLD 204716, including 1 rows selected for the primary serving, from label 2019-07-24, examined 2026-09-13.

Filed amounts, salt names and serving order

Magnesium (Form: as Di-Magnesium Malate)

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

Pure Encapsulations Magnesium EasySticks Natural Blueberry flavor files 30 servings per package, with no complete daily-frequency range for computing days, according to label 2019-07-24, calculated 2026-09-13.

Serving size as filed3.1 Gram(s) (1 stick pack)

Price per serving$0.3323 · computed from price observed 2026-09-07

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

Pure Encapsulations Magnesium EasySticks Natural Blueberry flavor files 1 magnesium percent-daily-value entries in NIH DSLD 204716; the check below applies the group-specific references in 21 CFR 101.9 to its 150 mg primary serving, calculated 2026-09-13.

Declared values and current-reference arithmetic
Group as filedDeclaredReferenceRecomputedDifference
Adults and children 4 or more years of age36%420 mg36%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.
