What the declared salt would weigh
Ortho Molecular Products Reacted Magnesium Powder declares 300 mg of elemental magnesium per serving in NIH DSLD 173935, requiring 2,127.66–2,535.93 mg of magnesium glycinate under the salt model calculated 2026-09-13.
| Step | Value | Evidence |
|---|---|---|
| Declared elemental magnesium | 300 mg per serving | observed · label 2018-02-23 |
| Resolved salt | Magnesium glycinate · label-row | computed · name resolved from filed text |
| Reference formula | Mg(C₂H₄NO₂)₂; 172.42 g/mol | computed · chemical reference |
| Elemental fraction | 11.83–14.1% by mass | computed |
| Why the fraction is a range | bisglycinate; chelate hydration varies by supplier | modelled · hydrate not specified |
| Compound mass per serving | 2,127.66–2,535.93 mg = 300 mg ÷ elemental fraction | computed |
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.

Magnesium lines as filed
Ortho Molecular Products Reacted Magnesium Powder retains 1 magnesium-related rows in NIH DSLD 173935, including 1 rows selected for the primary serving, from label 2018-02-23, examined 2026-09-13.
| Filed amount | Serving order | Filed salt / notes | Calculation role |
|---|---|---|---|
| 300 mg | 1 | bisglycinate Magnesium (Form: as TRAACS Magnesium Bisglycinate Chelate) | 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.
Package arithmetic · observed inputs, computed totals
What the package works out to
Ortho Molecular Products Reacted Magnesium Powder works out to 30 days per package at the label's own serving and filed frequency of 1 servings per day, according to label 2018-02-23, calculated 2026-09-13.
| Net contents as filed | 171 Gram(s); 6 Oz(s) |
|---|---|
| Serving size as filed | 5.7 Gram(s) (1 scoop) |
| Servings per package | 30 |
| Daily servings in the label instructions | 1 |
| Days per package at the label's own serving | 30 days |
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.
Benchmark · 20 observed prices in glycinate
A same-salt reference for this package
At the median cost per 100 mg observed across 20 glycinate labels ($0.1264), a package of this size (9,000 mg elemental in Ortho Molecular Products Reacted Magnesium Powder) would correspond to $11.37, using observations from 2026-08-10 to 2026-09-11, calculated 2026-09-13. This is a benchmark, not a retailer quote.
| Salt and number of observations | Magnesium glycinate · n = 20 |
|---|---|
| Median observed cost per 100 mg | $0.1264 |
| Filed elemental magnesium per package | 9,000 mg |
| Benchmark package equivalent | $11.37 = median EC100 × package elemental mg ÷ 100 |
| Evidence tier | benchmark · calculated 2026-09-13 |
The median is the middle sorted observation, or the average of the two middle observations for an even group. Each label contributes one observation. This value is neither an offer nor an estimate of a specific retailer's current price.
Percent daily value · observed and computed
The label's percent daily value, recomputed
Ortho Molecular Products Reacted Magnesium Powder files 1 magnesium percent-daily-value entries in NIH DSLD 173935; the check below applies the group-specific references in 21 CFR 101.9 to its 300 mg primary serving, calculated 2026-09-13.
| Group as filed | Declared | Reference | Recomputed | Difference |
|---|---|---|---|---|
| Adults and children 4 or more years of age | 75% | 420 mg | 71% | 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.
