AN Amazing Nutrition Amazing Formulas Magnesium Citrate 200 mg declares 200 mg of elemental magnesium per serving in NIH DSLD 251825, requiring 1,237.62–1,769.91 mg of magnesium citrate under the salt model calculated 2026-09-13.
| Step | Value | Evidence |
|---|---|---|
| Declared elemental magnesium | 200 mg per serving | observed · label 2021-08-23 |
| Resolved salt | Magnesium citrate · full-record | computed · name resolved from filed text |
| Reference formula | Mg₃(C₆H₅O₇)₂; 451.11 g/mol | computed · chemical reference |
| Elemental fraction | 11.3–16.16% by mass | computed |
| Why the fraction is a range | trimagnesium dicitrate 16.2%; dibasic and hydrated forms as low as 11.3% | modelled · hydrate not specified |
| Compound mass per serving | 1,237.62–1,769.91 mg = 200 mg ÷ elemental fraction | computed |
| Compound mass per discrete unit | 1,237.62–1,769.91 mg | 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
AN Amazing Nutrition Amazing Formulas Magnesium Citrate 200 mg retains 1 magnesium-related rows in NIH DSLD 251825, including 1 rows selected for the primary serving, from label 2021-08-23, examined 2026-09-13.
| Filed amount | Serving order | Filed salt / notes | Calculation role |
|---|---|---|---|
| 200 mg | 1 | Salt not identified in this row as of 2026-09-13 | 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.

What the package works out to
AN Amazing Nutrition Amazing Formulas Magnesium Citrate 200 mg works out to 120 days per package at the label's own serving and filed frequency of 1 servings per day, according to label 2021-08-23, calculated 2026-09-13.
| Net contents as filed | 120 Tablet(s) |
|---|---|
| Discrete units in the package | 120 |
| Serving size as filed | 1 Tablet(s) |
| Units per serving | 1 |
| Servings per package | 120 |
| Daily servings in the label instructions | 1 |
| Days per package at the label's own serving | 120 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 · 19 observed prices in citrate
A same-salt reference for this package
At the median cost per 100 mg observed across 19 citrate labels ($0.1039), a package of this size (24,000 mg elemental in AN Amazing Nutrition Amazing Formulas Magnesium Citrate 200 mg) would correspond to $24.94, 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 citrate · n = 19 |
|---|---|
| Median observed cost per 100 mg | $0.1039 |
| Filed elemental magnesium per package | 24,000 mg |
| Benchmark package equivalent | $24.94 = 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.
