Metabolic Maintenance Potassium/Magnesium Aspartate
Metabolic Maintenance Potassium/Magnesium Aspartate declares 99 mg of elemental magnesium per serving as aspartate, which would require 1,176 mg of the salt in each unit — more than the 1,100 mg a size 000 capsule holds; NIH DSLD 25095, label dated 2013-08-23, calculation 2026-09-13.

What the declared salt would weigh
Metabolic Maintenance Potassium/Magnesium Aspartate declares 99 mg of elemental magnesium per serving in NIH DSLD 25095, requiring 1,175.77 mg of magnesium aspartate under the salt model calculated 2026-09-13.
| Step | Value | Evidence |
|---|---|---|
| Declared elemental magnesium | 99 mg per serving | observed · label 2013-08-23 |
| Resolved salt | Magnesium aspartate · label-row | 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 | 1,175.77 mg = 99 mg ÷ elemental fraction | computed |
| Compound mass per discrete unit | 1,175.77 mg | computed |
At powder density 0.6–0.8 g/mL, 1,176 mg of powder exceeds every standard capsule size — the largest, 000, holds about 1,100 mg.
If the declared salt were the sole source of magnesium here, each capsule would need 1,176 mg of powder, which no standard capsule holds. So the label does not establish aspartate as the only source. A blend with a denser salt or a non-standard capsule could reconcile it. This is a statement about the label's arithmetic, not about what is in the bottle.
The verdict uses the most favourable reading for the product — the smallest compound mass the label allows. It excludes the shell and other ingredients; their unreported masses are not added as guesses.
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.

Observed means a value transcribed from a label or price observation. Computed means arithmetic or normalization of those inputs. Modelled means the result depends on a stated physical assumption, including capsule capacity. Evidence tiers and their limits.

Magnesium lines as filed
Metabolic Maintenance Potassium/Magnesium Aspartate retains 1 magnesium-related rows in NIH DSLD 25095, including 1 rows selected for the primary serving, from label 2013-08-23, examined 2026-09-13.
| Filed amount | Serving order | Filed salt / notes | Calculation role |
|---|---|---|---|
| 99 mg | 1 | aspartate Magnesium (Form: as Magnesium Aspartate) | 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
Metabolic Maintenance Potassium/Magnesium Aspartate has no filed serving count for package arithmetic in NIH DSLD 25095, according to label 2013-08-23, calculated 2026-09-13.
| Net contents as filed | 120 Capsule(s) |
|---|---|
| Discrete units in the package | 120 |
| Serving size as filed | 1 Capsule(s) |
| Units per serving | 1 |
| Servings per package | Servings not filed as of 2026-09-13 |
| Daily servings in the label instructions | 1 |
| Days per package at the label's own serving | Days not computable from filed frequency and serving count as of 2026-09-13 |
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
Metabolic Maintenance Potassium/Magnesium Aspartate files 1 magnesium percent-daily-value entries in NIH DSLD 25095; the check below applies the group-specific references in 21 CFR 101.9 to its 99 mg primary serving, calculated 2026-09-13.
| Group as filed | Declared | Reference | Recomputed | Difference |
|---|---|---|---|---|
| Adults and children 4 or more years of age | 25% | 420 mg | 24% | 1 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.
