Magnesium carbonate vs Magnesium malate

For 200 mg elemental magnesium, magnesium carbonate requires 694–807 mg of compound and magnesium malate requires 1,287–1,515 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.

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.

Magnesium carbonate: 200 mg worked example

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.

Magnesium malate: 200 mg worked example

For 200 mg elemental magnesium as magnesium malate, the chemistry accompanying the 2026-08-10 snapshot requires 1,287–1,515 mg of compound: 200 ÷ 0.1554 through 200 ÷ 0.1320, rounded to whole milligrams.

That requires 2–3 size 00 capsules at 730 mg of compound per capsule, before other ingredients. The mass interval reflects anhydrous or dihydrate.

Compound mass reference in 25 mg elemental increments

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.

How each salt's capsule labels distribute

In the 2026-08-10 snapshot, the magnesium carbonate form group has 0 audited capsule labels and the magnesium malate group has 17; their distributions below use the mass-budget counts stored for each form, at powder density 0.6–0.8 g/mL.

Salt groupAll labelsAudited capsulesFits 0/00Needs 000Exceeds 000
Magnesium carbonate230000
Magnesium malate7317548

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 malate has 5 of 17 audited capsule labels at or below 730 mg minimum compound mass per capsule, 4 above 730 mg but at or below 1100 mg, and 8 above 1100 mg. Its other 56 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

Which measurements are attached to these salts?

As of the literature review dated 2026-09-11, the supplied study collection associates 2 publications with magnesium carbonate and 3 with magnesium malate; the combined list contains 5 unique publications, with shared records printed once.

Study-set membership · reviewed 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.

  1. Effects of short-term magnesium supplementation on ionized, total magnesium and other relevant electrolytes levels.

    Biometals : an international journal on the role of metal ions in biology, biochemistry, and medicine · 2022 · PMID 35041150

    Design
    Short-term, 10-day supplementation study in 61 healthy young female adults, comparing three magnesium supplement forms: magnesium oxide (powder/granulate), magnesium citrate, and magnesium carbonate (effervescent tablets).
    What it measured
    Ionized magnesium concentration and its percentage of total magnesium; serum total magnesium concentration; other serum electrolyte levels — each assessed at baseline and after the 10-day intervention.
    Limits
    Healthy young female adults only, no male or older/deficient populations studied; short 10-day intervention with no longer-term follow-up; three specific product formulations were tested, so results may not generalize to other products of the same salts; the abstract does not report the per-arm breakdown of the 61 participants.

  2. Dose-Dependent Absorption Profile of Different Magnesium Compounds

    Biological Trace Element Research · 2020 · PMID 30761462

    Design
    Absorption of several magnesium compounds profiled across doses rather than at a single dose.
    What it measured
    Absorption is treated as dose-dependent, so a comparison made at one dose need not hold at another — which is why single-dose head-to-head results disagree.
    Limits
    Compound coverage and sample size vary by arm; read the paper before carrying any single figure across.

  3. Timeline (Bioavailability) of Magnesium Compounds in Hours: Which Magnesium Compound Works Best?

    Biological trace element research · 2019 · PMID 29679349

    Design
    Single-dose administration of 400 mg/70 kg magnesium as one of five compounds (magnesium sulfate, magnesium oxide, magnesium acetyl taurate, magnesium citrate, magnesium malate) to Sprague Dawley rats, with a control group, followed by time-dependent tissue and serum sampling.
    What it measured
    Time-dependent magnesium absorption profile (area under the curve) in serum; magnesium tissue penetration and concentration, including brain tissue; behavioral indicators (e.g., anxiety-related behavior) recorded in the animals.
    Limits
    Animal model (Sprague Dawley rats), not humans — extrapolation of pharmacokinetic and behavioral findings to people is not established; single dose only, no chronic-dosing data; per-compound group sample size is not stated in the abstract; behavioral endpoints were measured only in rodents. The tested acetyl taurate is distinct from the unmodified taurate in the chemistry table.

  4. Scottsdale Magnesium Study: Absorption, Cellular Uptake, and Clinical Effectiveness of a Timed-Release Magnesium Supplement in a Standard Adult Clinical Population.

    Journal of the American College of Nutrition · 2018 · PMID 29425476

    Design
    Placebo-controlled study at two clinics in 91 adults; 53 received MagSRT (500 mg dimagnesium malate plus vitamins B6, B12, and folate, dosed as 2 tablets containing 250 mg elemental magnesium) and the remainder received placebo. A subset of 24 MagSRT participants continued the trial to 90 days.
    What it measured
    Serum magnesium at 4 and 8 hours post-dose; red blood cell (RBC) magnesium at baseline, 30 days, and 90 days (subset); magnesium status questionnaire score at baseline, 30 days, and 90 days.
    Limits
    Comparator was placebo only, not a head-to-head comparison against other magnesium salts; the tested product combined dimagnesium malate with B-vitamins and folate, so effects cannot be isolated to the malate salt alone; 90-day follow-up was limited to a subset (n=24) of the original 53 treated participants; outcome included a self-reported symptom questionnaire alongside biochemical markers.

  5. Study of magnesium bioavailability from ten organic and inorganic Mg salts in Mg-depleted rats using a stable isotope approach

    Magnesium Research · 2005 · PMID 16548135

    Design
    Eighty male Wistar rats fed a magnesium-depleted diet for three weeks, then randomised into ten groups, each receiving a different magnesium salt labelled with a stable isotope.
    What it measured
    Stable isotopes allow absorption and retention to be traced directly rather than inferred from urine, across ten salts at once — the widest head-to-head comparison in the literature.
    Limits
    Rats, not people, and magnesium-depleted rats at that: depletion itself raises absorption. The breadth of the comparison is its value; the species is its limit.

Price observations within each salt

As of 2026-09-13, the published price set contains 0 verified magnesium carbonate matches and 6 verified magnesium malate 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.
