Magnesium glycinate vs Magnesium taurate

For 200 mg elemental magnesium, magnesium glycinate requires 1,418–1,691 mg of compound and magnesium taurate requires 2,260 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 11.83–14.10% magnesium by mass for magnesium glycinate and 8.85% for magnesium taurate; 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 glycinate: 200 mg worked example

For 200 mg elemental magnesium as magnesium glycinate, the chemistry accompanying the 2026-08-10 snapshot requires 1,418–1,691 mg of compound: 200 ÷ 0.1410 through 200 ÷ 0.1183, 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 bisglycinate; chelate hydration varies by supplier.

Magnesium taurate: 200 mg worked example

For 200 mg elemental magnesium as magnesium taurate, the chemistry accompanying the 2026-08-10 snapshot requires 2,260 mg of compound: 200 ÷ 0.0885, 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(C₂H₆NO₃S)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.

How each salt's capsule labels distribute

In the 2026-08-10 snapshot, the magnesium glycinate form group has 42 audited capsule labels and the magnesium taurate group has 8; 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 glycinate12642161313
Magnesium taurate128116

At 2026-08-10, magnesium glycinate has 16 of 42 audited capsule labels at or below 730 mg minimum compound mass per capsule, 13 above 730 mg but at or below 1100 mg, and 13 above 1100 mg. Its other 84 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 taurate has 1 of 8 audited capsule labels at or below 730 mg minimum compound mass per capsule, 1 above 730 mg but at or below 1100 mg, and 6 above 1100 mg. Its other 4 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 6 publications with magnesium glycinate and 1 with magnesium taurate; the combined list contains 7 unique publications, with shared records printed once.

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. Comparative Clinical Study on Magnesium Absorption and Side Effects After Oral Intake of Microencapsulated Magnesium (MAGSHAPE™ Microcapsules) Versus Other Magnesium Sources.

    Nutrients · 2024 · PMID 39770988

    Design
    Double-blind, randomized, cross-over clinical study in 40 healthy women and men. Participants followed a low-magnesium diet for 7 days and fasted 8 hours, then received a single oral dose of each of four products in cross-over fashion: microencapsulated magnesium (Mg-MS / MAGSHAPE), magnesium oxide (MgO), magnesium citrate (Mg-C), and magnesium bisglycinate (Mg-BG). Blood was drawn by digital puncture before dosing (0 h) and at 1, 4, and 6 hours after each product.
    What it measured
    Plasma magnesium concentration at 0, 1, 4, and 6 hours after oral intake of each of the four products; gastrointestinal side effects (intestinal motility, sensations of gastric heaviness) associated with each product.
    Limits
    Single-dose exposure per product, not chronic supplementation; sample size n=40; a specific proprietary microencapsulation technology was tested, which may not generalize to other encapsulation methods; plasma magnesium was the only absorption marker used (no urinary or tissue measurement).
  2. The bioaccessibility and tolerability of marine-derived sources of magnesium and calcium.

    Methods (San Diego, Calif.) · 2024 · PMID 38608850

    Design
    Two-part study. (1) In vitro digestion (INFOGEST method) comparing solubility of Aquamin-Mg (seawater-derived, 12% magnesium), a commercially available magnesium bisglycinate, and a specific branded magnesium bisglycinate (PrizMAG) during simulated gastric and intestinal digestion phases, with and without co-administered food. (2) A randomized, double-blind, placebo-controlled 12-week study in a small cohort of healthy older adults given a combined Aquamin-Mg/Aquamin-F supplement.
    What it measured
    In vitro mineral solubility during simulated gastric and intestinal digestion phases; adverse-event reporting and tolerability over the 12-week human study arm.
    Limits
    The solubility comparison was performed in vitro (simulated digestion model), not as in vivo human absorption; the human arm assessed tolerability/safety only, not comparative bioavailability; the human cohort was described only as small and limited to older adults, with no numeric sample size given in the abstract.
  3. 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.
  4. 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.
  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.
  6. Mg citrate found more bioavailable than other Mg preparations in a randomised, double-blind study

    Magnesium Research · 2003 · PMID 14596323

    Design
    Randomised, double-blind, placebo-controlled parallel study in 46 healthy individuals, 300 mg of elemental magnesium per day, comparing an amino-acid chelate, citrate and oxide.
    What it measured
    Relative bioavailability of the three preparations was compared at an equal elemental dose.
    Limits
    46 participants, healthy, 300 mg per day; “amino-acid chelate” is a class rather than one defined compound, so the chelate arm is not a single substance.
  7. Bioavailability of magnesium diglycinate vs magnesium oxide in patients with ileal resection

    JPEN: Journal of Parenteral and Enteral Nutrition · 1995 · PMID 7815675

    Design
    Comparison of magnesium diglycinate (a chelate) with magnesium oxide in patients who had undergone ileal resection.
    What it measured
    The work followed in vitro and in situ findings suggesting diglycinate is absorbed by a different route than inorganic salts, and tested that in patients with impaired absorption.
    Limits
    Patients after ileal resection are a specific clinical population with poor absorption to begin with; results do not transfer to people with an intact gut.

Retail observations · after chemistry and evidence

Price observations within each salt

As of 2026-09-13, the published price set contains 11 verified magnesium glycinate matches and 0 verified magnesium taurate 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.

Magnesium glycinate: its own retail sample
