| Declared elemental magnesium | 49 mg per serving | observed · label 2024-03-22 |
| Resolved salt | Magnesium aspartate · full-record | computed · name resolved from filed text |
| Reference formula | Mg(C₄H₆NO₄)₂; 288.5 g/mol | computed · chemical reference |
| Elemental fraction | 8.42% by mass | computed |
| Compound mass per serving | 581.95 mg = 49 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
BulkSupplements.com Magnesium D-Aspartate retains 1 magnesium-related rows in NIH DSLD 310742, including 1 rows selected for the primary serving, from label 2024-03-22, examined 2026-09-13.
| Filed amount | Serving order | Filed salt / notes | Calculation role |
|---|---|---|---|
| 49 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.
Package arithmetic · observed inputs, computed totals
What the package works out to
BulkSupplements.com Magnesium D-Aspartate works out to 184–368 days per package at the label's own serving and filed frequency of 1–2 servings per day, according to label 2024-03-22, calculated 2026-09-13.
| Net contents as filed | 250 Gram(s); 8.8 Ounce(s) |
|---|---|
| Serving size as filed | 680 mg (about 1/4 tsp) |
| Servings per package | 368 |
| Daily servings in the label instructions | 1–2 |
| Days per package at the label's own serving | 184–368 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.
Percent daily value · observed and computed
The label's percent daily value, recomputed
BulkSupplements.com Magnesium D-Aspartate files 1 magnesium percent-daily-value entries in NIH DSLD 310742; the check below applies the group-specific references in 21 CFR 101.9 to its 49 mg primary serving, calculated 2026-09-13.
| Group as filed | Declared | Reference | Recomputed | Difference |
|---|---|---|---|---|
| Adults and children 4 or more years of age | 12% | 420 mg | 12% | 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.
