Equal elemental amount · snapshot 2026-08-10
For 200 mg elemental magnesium, magnesium lactate requires 1,665–1,963 mg of compound and magnesium l-threonate requires 2,424 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 10.19–12.01% magnesium by mass for magnesium lactate and 8.25% for magnesium l-threonate; dividing the elemental amount by these fractions gives the compound masses below.
| Property | Magnesium lactate | Magnesium L-threonate |
|---|---|---|
| Elemental Mg by compound mass | 10.19–12.01% | 8.25% |
| Anhydrous reference formula | Mg(C₃H₅O₃)₂ | Mg(C₄H₇O₅)₂ |
| Molar mass of that reference formula | 202.45 g/mol | 294.50 g/mol |
| Composition interval | anhydrous 12.01% or dihydrate 10.19% (238.48 g/mol) | One formula fraction used for Mg(C₄H₇O₅)₂ in this model. |
| Compound for 100 mg elemental Mg | 833–981 mg | 1,212 mg |
| Compound for 200 mg elemental Mg | 1,665–1,963 mg | 2,424 mg |
| Compound for 400 mg elemental Mg | 3,331–3,925 mg | 4,848 mg |
| Size 00 capsules for 100 mg elemental Mg | 2 capsules at 730 mg compound fill each | 2 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 lactate, the chemistry accompanying the 2026-08-10 snapshot requires 1,665–1,963 mg of compound: 200 ÷ 0.1201 through 200 ÷ 0.1019, rounded to whole milligrams.
That requires 3 size 00 capsules at 730 mg of compound per capsule, before other ingredients. The mass interval reflects anhydrous 12.01% or dihydrate 10.19% (238.48 g/mol).
For 200 mg elemental magnesium as magnesium l-threonate, the chemistry accompanying the 2026-08-10 snapshot requires 2,424 mg of compound: 200 ÷ 0.0825, 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(C₄H₇O₅)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 2026-10-17. 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.

A whole capsule count describes the minimum number of modelled containers needed to hold compound mass. It does not establish the dimensions, packing density or excipient content of a retail product. The ingredient list and serving statement on each linked record supply the product-specific context.
Declarations against capacity
In the 2026-08-10 snapshot, the magnesium lactate form group has 1 audited capsule labels and the magnesium l-threonate group has 6; their distributions below use the mass-budget counts stored for each form, at powder density 0.8 g/mL, the top of the usual 0.6–0.8 range.
| Salt group | All labels | Audited capsules | Fits 0/00 | Needs 000 | Exceeds 000 |
|---|---|---|---|---|---|
| Magnesium lactate | 6 | 1 | 1 | 0 | 0 |
| Magnesium L-threonate | 9 | 6 | 6 | 0 | 0 |
At 2026-08-10, magnesium lactate has 1 of 1 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 5 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 l-threonate has 6 of 6 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 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 lactate and 0 with magnesium l-threonate; the combined list contains 2 unique publications, with shared records printed once.

|---|---|---|
| Magnesium lactate | 2 | 2001–2005 |
| Magnesium L-threonate | 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.

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.
As of 2026-10-17, magnesium lactate has 0 verified matches and 0 pending matches in the price set. No verified median is available as of 2026-10-17. Observation dates: No published observations as of 2026-10-17.
