Magnesium lines as filed

Solgar Magnesium with Vitamin B6 retains 1 magnesium-related rows in NIH DSLD 218431, including 1 rows selected for the primary serving, from label 2020-04-23, examined 2026-09-13.

Magnesium (Form: as Magnesium Oxide)

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

Solgar Magnesium with Vitamin B6 works out to 83 days per package at the label's own serving and filed frequency of 1 servings per day, according to label 2020-04-23, calculated 2026-09-13.

Price per day at the label's own serving$0.2019 · computed from price observed 2026-08-10

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

Solgar Magnesium with Vitamin B6 files 1 magnesium percent-daily-value entries in NIH DSLD 218431; 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 age95%420 mg95%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.

Other ingredients in the filed record

Solgar Magnesium with Vitamin B6 lists 6 other ingredients in NIH DSLD 218431, label dated 2020-04-23, 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.
