Equal elemental amount · snapshot 2026-08-10
For 200 mg elemental magnesium, magnesium carbonate requires 694–807 mg of compound and magnesium orotate requires 2,751 mg, using the chemistry accompanying the 2026-08-10 label snapshot. This difference follows from the magnesium fraction of each compound. It requires no absorption-study assumption: the same elemental mass travels with a different mass of the rest of the compound.

At 100, 200 and 400 mg elemental magnesium, the chemistry accompanying the 2026-08-10 snapshot uses 24.78–28.83% magnesium by mass for magnesium carbonate and 7.27% for magnesium orotate; dividing the elemental amount by these fractions gives the compound masses below.
| Property | Magnesium carbonate | Magnesium orotate |
|---|---|---|
| Elemental Mg by compound mass | 24.78–28.83% | 7.27% |
| Anhydrous reference formula | MgCO₃ | Mg(C₅H₃N₂O₄)₂ |
| Molar mass of that reference formula | 84.31 g/mol | 334.49 g/mol |
| Composition interval | anhydrous or hydrated; labels rarely state which | One formula fraction used for Mg(C₅H₃N₂O₄)₂ in this model. |
| Compound for 100 mg elemental Mg | 347–404 mg | 1,376 mg |
| Compound for 200 mg elemental Mg | 694–807 mg | 2,751 mg |
| Compound for 400 mg elemental Mg | 1,387–1,614 mg | 5,502 mg |
| Size 00 capsules for 100 mg elemental Mg | 1 capsules at 730 mg compound fill each | 2 capsules at 730 mg compound fill each |
| Size 00 capsules for 200 mg elemental Mg | 1–2 capsules at 730 mg compound fill each | 4 capsules at 730 mg compound fill each |

Molar masses refer to the displayed anhydrous formulas. Hydrated or composition-ambiguous readings use the full fraction interval from the chemistry layer. Compound masses are rounded to whole milligrams; capsule counts round the unrounded mass divided by 730 mg upward at each interval endpoint.
For 200 mg elemental magnesium as magnesium carbonate, the chemistry accompanying the 2026-08-10 snapshot requires 694–807 mg of compound: 200 ÷ 0.2883 through 200 ÷ 0.2478, rounded to whole milligrams.
That requires 1–2 size 00 capsules at 730 mg of compound per capsule, before other ingredients. The mass interval reflects anhydrous or hydrated; labels rarely state which.
For 200 mg elemental magnesium as magnesium orotate, the chemistry accompanying the 2026-08-10 snapshot requires 2,751 mg of compound: 200 ÷ 0.0727, rounded to whole milligrams.
That requires 4 size 00 capsules at 730 mg of compound per capsule, before other ingredients. The model uses the Mg(C₅H₃N₂O₄)₂ fraction throughout.
40 arithmetic inputs from 25 to 1,000 mg elemental magnesium are converted below using the two salt fractions and the capsule capacities accompanying the 2026-08-10 snapshot, calculated 2026-09-13. These are mass-conversion inputs, independent of any consumption schedule.
Each compound interval divides the elemental input by the high and low magnesium fractions. Each capsule interval divides those unrounded compound masses by the listed fill capacity, then rounds upward. The three capsule sizes use 545, 730 and 1100 mg of compound per capsule respectively, before other ingredients.

Declarations against capacity
In the 2026-08-10 snapshot, the magnesium carbonate form group has 0 audited capsule labels and the magnesium orotate group has 5; their distributions below use the mass-budget counts stored for each form, at powder density 0.6–0.8 g/mL.
| Salt group | All labels | Audited capsules | Fits 0/00 | Needs 000 | Exceeds 000 |
|---|---|---|---|---|---|
| Magnesium carbonate | 23 | 0 | 0 | 0 | 0 |
| Magnesium orotate | 8 | 5 | 4 | 0 | 1 |
At 2026-08-10, magnesium carbonate has 0 of 0 audited capsule labels at or below 730 mg minimum compound mass per capsule, 0 above 730 mg but at or below 1100 mg, and 0 above 1100 mg. Its other 23 labels have no capsule verdict in this group, either because they are not classified as capsules or because a mass budget is unavailable.
At 2026-08-10, magnesium orotate has 4 of 5 audited capsule labels at or below 730 mg minimum compound mass per capsule, 0 above 730 mg but at or below 1100 mg, and 1 above 1100 mg. Its other 3 labels have no capsule verdict in this group, either because they are not classified as capsules or because a mass budget is unavailable.
The audit divides a label's elemental amount by its assigned salt fraction and serving-unit count. It uses the highest fraction, hence the smallest required mass. A hydration interval can move a nominally fitting label into a larger size at its high-mass end. A result exceeding 000 means the assigned single salt exceeds this fill model even at the low-mass end.
Form groups include names in extracted primary rows, resolved salts and full-record salt mentions, and can overlap; a capsule verdict requires a single assigned salt matching this group. These are counts of label declarations, with the capsule model allocating the fill to the compound. Inspect individual serving statements and assigned salts in the audit register and the linked form pages.
Literature coverage
As of the literature review dated 2026-09-11, the supplied study collection associates 2 publications with magnesium carbonate and 0 with magnesium orotate; the combined list contains 2 unique publications, with shared records printed once.

| Magnesium orotate | 0 | No studies mapped as of 2026-09-11 |
Membership means that at least one selected salt appears in the study's recorded coverage; it does not mean every paper directly compares this exact pair. In particular, an amino-acid-chelate arm does not establish a chemically defined bisglycinate preparation. Each record below retains its actual design, population, read-out and limits.

Retail observations · after chemistry and evidence
As of 2026-09-13, the published price set contains 0 verified magnesium carbonate matches and 0 verified magnesium orotate matches. Each table below contains one salt and its own sample size; verified medians describe only that salt's verified rows.
EC100 = container price ÷ (declared elemental mg per serving × servings per container ÷ 100). It normalizes the container's elemental amount. The observations use one-time item prices, without coupons or subscriptions and excluding shipping. The tables retain the two salts' page order; sorting operates inside an individual salt table.
