Magnesium aspartate vs Magnesium gluconate

For 200 mg elemental magnesium, magnesium aspartate requires 2,375 mg of compound and magnesium gluconate requires 3,413 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.

Show the working

Same elemental amount, different compound mass

At 100, 200 and 400 mg elemental magnesium, the chemistry accompanying the 2026-08-10 snapshot uses 8.42% magnesium by mass for magnesium aspartate and 5.86% for magnesium gluconate; dividing the elemental amount by these fractions gives the compound masses below.

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 aspartate: 200 mg worked example

For 200 mg elemental magnesium as magnesium aspartate, the chemistry accompanying the 2026-08-10 snapshot requires 2,375 mg of compound: 200 ÷ 0.0842, 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(C₄H₆NO₄)₂ fraction throughout.

Magnesium gluconate: 200 mg worked example

For 200 mg elemental magnesium as magnesium gluconate, the chemistry accompanying the 2026-08-10 snapshot requires 3,413 mg of compound: 200 ÷ 0.0586, rounded to whole milligrams.

That requires 5 size 00 capsules at 730 mg of compound per capsule, before other ingredients. The model uses the Mg(C₆H₁₁O₇)₂ fraction throughout.

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.

Declarations against capacity

How each salt's capsule labels distribute

In the 2026-08-10 snapshot, the magnesium aspartate form group has 15 audited capsule labels and the magnesium gluconate group has 2; 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 aspartate46153111
Magnesium gluconate202200

At 2026-08-10, magnesium aspartate has 3 of 15 audited capsule labels at or below 730 mg minimum compound mass per capsule, 1 above 730 mg but at or below 1100 mg, and 11 above 1100 mg. Its other 31 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 gluconate has 2 of 2 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 18 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 aspartate and 2 with magnesium gluconate; the combined list contains 3 unique publications, with shared records printed once.

Study-set membership · reviewed 2026-09-11
SaltPublicationsPublication years
Magnesium aspartate22001–2005

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. 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.

  2. Bioavailability of US commercial magnesium preparations

    Magnesium Research · 2001 · PMID 11794633

    Design
    Four commercially available US preparations given to healthy volunteers; bioavailability measured as the increment in urinary magnesium excretion.
    What it measured
    The study set out to test the claim that organic magnesium salts are more easily absorbed than inorganic ones, using urinary excretion as the read-out.
    Limits
    Healthy volunteers, small sample, urinary excretion as a proxy for absorption rather than a direct measurement of retention.

  3. Blood and urinary magnesium kinetics after oral magnesium supplements.

    Clinical therapeutics · 1992 · PMID 1468087

    Design
    Randomized, crossover study in 12 healthy normomagnesemic subjects: a baseline period followed by three separate one-week supplementation trials at 16 mmol/dose — magnesium chloride solution, slow-release magnesium chloride tablets, and magnesium gluconate tablets — with a standardized diet during each trial.
    What it measured
    Urinary magnesium excretion in 0-4, 4-8, 8-12, and 12-24 hour collections; intraleukocyte, total serum, and ultrafiltrable serum magnesium at 0, 1, 2, 3, 4, 8, 12, and 24 hours; area-under-curve for each compartment relative to baseline for each supplement form.
    Limits
    Very small sample (n=12); only two chemical forms tested (chloride in two formulations, plus gluconate); short trial duration per arm (24 hours, with weekly crossover intervals); normomagnesemic (not magnesium-deficient) subjects only.
