Magnesium lines as filed
Trace Minerals Research Stress-X Magnesium Powder Lemon Lime retains 1 magnesium-related rows in NIH DSLD 61989, including 1 rows selected for the primary serving, from label 2016-06-24, examined 2026-09-13.
| Filed amount | Serving order | Filed salt / notes | Calculation role |
|---|---|---|---|
| 350 mg | 1 | carbonate, malate Magnesium (Form: as Magnesium Malate, 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.

Cost per 100 mg within malate
Trace Minerals Research Stress-X Magnesium Powder Lemon Lime's $0.0571 per 100 mg of elemental magnesium is at percentile 11 among 9 malate 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 | $19.99 on 2026-09-07 |
|---|---|
| Cost per 100 mg elemental | $0.0571 |
| Observed prices in malate | 9 confirmed matches |
| Percentile | 11 |
| Match confidence | legacy-verified |
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
Trace Minerals Research Stress-X Magnesium Powder Lemon Lime works out to 50–100 days per package at the label's own serving and filed frequency of 1–2 servings per day, according to label 2016-06-24, calculated 2026-09-13.
| Net contents as filed | 17.6 oz.; 500 Gram(s) |
|---|---|
| Serving size as filed | 0.5–1 tsp (2.5-5 g) |
| Servings per package | 100 |
| Daily servings in the label instructions | 1–2 |
| Days per package at the label's own serving | 50–100 days |
| Price per serving | $0.1999 · computed from price observed 2026-09-07 |
| Price per day at the label's own serving | $0.1999–0.3998 · 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
Trace Minerals Research Stress-X Magnesium Powder Lemon Lime files 1 magnesium percent-daily-value entries in NIH DSLD 61989; 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 | 86% | 420 mg | 83% | 3 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.
