What the declared salt would weigh

NFH Magnesium Citrate SAP declares 136 mg of elemental magnesium per serving in NIH DSLD 273296, requiring 841.58–1,203.54 mg of magnesium citrate 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

NFH Magnesium Citrate SAP has 11 published fields below, traced to NIH DSLD 273296 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.

Magnesium lines as filed

NFH Magnesium Citrate SAP retains 1 magnesium-related rows in NIH DSLD 273296, including 1 rows selected for the primary serving, from label 2023-01-23, 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.

Package arithmetic · observed inputs, computed totals

What the package works out to

NFH Magnesium Citrate SAP works out to 45 days per package at the label's own serving and filed frequency of 2 servings per day, according to label 2023-01-23, 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.

Other ingredients in the filed record

NFH Magnesium Citrate SAP lists 3 other ingredients in NIH DSLD 273296, label dated 2023-01-23, examined 2026-09-13.

Capsule material: vegetarian. The material classification follows the filed ingredient names; it is not a test of the shell.

This label lists magnesium stearate, whose reference elemental fraction is 4.1% by mass. No stearate quantity is available in this record as of 2026-09-13, so its magnesium contribution cannot be quantified or added to the Supplement Facts magnesium total.
