Magnesium lines as filed
Nature's Lab Magnesium Soothe 350 mg Raspberry Lemon retains 1 magnesium-related rows in NIH DSLD 207246, including 1 rows selected for the primary serving, from label 2019-10-23, examined 2026-09-13.
| Filed amount | Serving order | Filed salt / notes | Calculation role |
|---|---|---|---|
| 350 mg | 1 | carbonate, citrate Magnesium (Form: as Magnesium Citrate, Magnesium Carbonate) | 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.
Within one salt · computed from observed prices
Cost per 100 mg within citrate
Nature's Lab Magnesium Soothe 350 mg Raspberry Lemon's $0.0514 per 100 mg of elemental magnesium is at percentile 11 among 19 citrate labels with observed prices, using confirmed gold-set matches observed 2026-08-10 to 2026-09-11, calculated 2026-09-13.
| Observed item price · Amazon | $17.99 on 2026-08-10 |
|---|---|
| Cost per 100 mg elemental | $0.0514 |
| Observed prices in citrate | 19 confirmed matches |
| Percentile | 11 |
| Match confidence | legacy-provisional |
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
Nature's Lab Magnesium Soothe 350 mg Raspberry Lemon works out to 50 days per package at the label's own serving and filed frequency of 2 servings per day, according to label 2019-10-23, calculated 2026-09-13.
| Net contents as filed | 16.5 oz.; 463 Gram(s) |
|---|---|
| Serving size as filed | 4.6–6.9 Gram(s) (1-1.5 rounded tsp) |
| Servings per package | 100 |
| Daily servings in the label instructions | 2 |
| Days per package at the label's own serving | 50 days |
| Price per serving | $0.1799 · computed from price observed 2026-08-10 |
| Price per day at the label's own serving | $0.3598 · 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
Nature's Lab Magnesium Soothe 350 mg Raspberry Lemon files 1 magnesium percent-daily-value entries in NIH DSLD 207246; the check below applies the group-specific references in 21 CFR 101.9 to its 350 mg primary serving, calculated 2026-09-13.
| Group as filed | Declared | Reference | Recomputed | Difference |
|---|---|---|---|---|
| Adults and children 4 or more years of age | 87% | 420 mg | 83% | 4 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.
