Mass budget · computed; capsule comparison · modelled

What the declared salt would weigh

NOW Magnesium Malate Caps declares 95 mg of elemental magnesium per serving in NIH DSLD 313611, requiring 611.33–719.7 mg of magnesium malate under the salt model calculated 2026-09-13.

Size 0 holds about 545 mg, size 00 about 730 mg, and size 000 about 1,100 mg at powder density 0.6–0.8 g/mL. These are model inputs, not measurements of this product's capsule. Read the mass-budget method.

Label facts and derived measurements

The numbers for this label

NOW Magnesium Malate Caps has 14 published fields below, traced to NIH DSLD 313611 and the 2026-08-10 registry snapshot, with calculations dated 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.

Source transcription · observed

Magnesium lines as filed

NOW Magnesium Malate Caps retains 1 magnesium-related rows in NIH DSLD 313611, including 1 rows selected for the primary serving, from label 2024-05-23, examined 2026-09-13.

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.

Cost per 100 mg within malate

NOW Magnesium Malate Caps's $0.1712 per 100 mg of elemental magnesium is at percentile 78 among 9 malate labels with observed prices, using confirmed gold-set matches observed 2026-08-10 to 2026-09-11, calculated 2026-09-13.

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

NOW Magnesium Malate Caps works out to 60 days per package at the label's own serving and filed frequency of 3 servings per day, according to label 2024-05-23, calculated 2026-09-13.

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

NOW Magnesium Malate Caps files 1 magnesium percent-daily-value entries in NIH DSLD 313611; the check below applies the group-specific references in 21 CFR 101.9 to its 95 mg primary serving, calculated 2026-09-13.

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.
