Magnesium hydroxide vs Magnesium lactate

For 200 mg elemental magnesium, magnesium hydroxide requires 480 mg of compound and magnesium lactate requires 1,665 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.

Same elemental amount, different compound mass

At 100, 200 and 400 mg elemental magnesium, the chemistry accompanying the 2026-08-10 snapshot uses 41.68% magnesium by mass for magnesium hydroxide and 12.01% for magnesium lactate; 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 hydroxide: 200 mg worked example

For 200 mg elemental magnesium as magnesium hydroxide, the chemistry accompanying the 2026-08-10 snapshot requires 480 mg of compound: 200 ÷ 0.4168, rounded to whole milligrams.

That requires 1 size 00 capsules at 730 mg of compound per capsule, before other ingredients. The model uses the Mg(OH)₂ fraction throughout.

Magnesium lactate: 200 mg worked example

For 200 mg elemental magnesium as magnesium lactate, the chemistry accompanying the 2026-08-10 snapshot requires 1,665 mg of compound: 200 ÷ 0.1201, rounded to whole milligrams.

That requires 3 size 00 capsules at 730 mg of compound per capsule, before other ingredients. The model uses the Mg(C₃H₅O₃)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 hydroxide form group has 1 audited capsule labels and the magnesium lactate group has 1; their distributions below use the mass-budget counts stored for each form, at powder density 0.6–0.8 g/mL.

Capsule mass budgets within each form group · 2026-08-10
Salt group	All labels	Audited capsules	Fits 0/00	Needs 000	Exceeds 000
Magnesium hydroxide	10	1	1	0	0
Magnesium lactate	6	1	1	0	0

At 2026-08-10, magnesium hydroxide 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 9 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 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.

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 1 publications with magnesium hydroxide and 2 with magnesium lactate; the combined list contains 3 unique publications, with shared records printed once.

Study-set membership · reviewed 2026-09-11
Salt	Publications	Publication years
Magnesium hydroxide	1	2025–2025
Magnesium lactate	2	2001–2005

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.

Comparing the Bioavailability of Two Seawater-Derived Magnesium Preparations.
Journal of medicinal food · 2025 · PMID 40955524
Design
Double-blind, randomized, three-arm crossover study in 20 healthy young men and women: placebo (maltodextrin), seawater-derived magnesium citrate (Aquamin-Mg, minimum 10% elemental magnesium), and seawater-derived magnesium hydroxide (Aquamin-MgTg, minimum 33% elemental magnesium). Total magnesium doses were standardized to the RDA for elemental magnesium.
What it measured
Incremental 18-hour urinary magnesium excretion as the relative-bioavailability marker; serum magnesium concentration at 1 and 2 hours post-ingestion (colorimetric assay, run in triplicate).
Limits
Small sample (n=20); healthy young adults only, not a magnesium-deficient or older population; only two seawater-derived preparations plus placebo were tested, no head-to-head comparison against standard magnesium citrate/oxide/glycinate salts; short observation window (18 h urine, 2 h serum).
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.
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.
