Pure Encapsulations Magnesium vs Magnesium 5: A Capsule-Dose Comparison

TL;DR:

  • The selected Pure Encapsulations US MG9 capsule declares 120 mg magnesium as glycinate; Magnesium 5 uses a three-capsule serving and adds other nutrients.
  • The updated Magnesium 5 Supplement Facts panel lists five elemental-magnesium contributions totalling 250.5 mg per three capsules. Its current product page uses the same total and five named forms; still confirm the market and current pack.
  • A single-mineral capsule can fit a focused plan; a broader formula can fit a different plan after all co-nutrients are reviewed. Neither form count nor capsule count proves a better outcome.

Editorial answer: Pure Encapsulations Magnesium Glycinate and BioEssentials Magnesium 5 answer different capsule-buying questions. The selected Pure US product supplies a clearly stated magnesium amount in each capsule; Magnesium 5 combines several magnesium forms with additional nutrients in a three-capsule daily serving. A useful comparison therefore starts with the unit, the complete ingredient list and whether the sources agree.

The Magnesium 5 Supplement Facts panel was updated on 7 September 2026. Its five listed elemental-magnesium contributions total 250.5 mg per three capsules, matching the current product page. Earlier versions of this guide cited 262 mg on an older label and 253 mg on the product page; those are not the current serving figures used below.

Identify the Two Capsule Products

The comparator is the 90-capsule option on Pure Encapsulations' official US Magnesium Glycinate consumer page. Its linked Supplement Facts panel, visually checked on 6 September 2026, declares 120 mg magnesium as magnesium glycinate per capsule. That illustration shows a 30-capsule pack; the selected 90-capsule pack is separately identified on the current page and as professional order code MG9 in the brand's product documentation, which corroborates the same per-capsule formula. MG9 is not the consumer shop's commerce SKU.

The current consumer page gives directions of one to four capsules daily with food. That range describes the US label, not a suggested target for every reader. The professional product sheet is the linked-sheet source summarized in the comparison graphic; the directly accessible panel above lets a reader inspect the per-capsule amount.

The BioEssentials side is the France-market Magnesium 5 product, with 90 capsules and a label direction of three daily with water, preferably during a meal. The review is tied to that regional label and the current public page. Market identity matters: a regional product name does not establish that every listing worldwide has the same panel.

Compare the Same Denominator

A per-capsule amount and a per-day amount have different denominators. Write the substance, amount and serving together before comparing front-label numbers.

Field Pure US MG9 Magnesium 5 FR
Pack count 90 capsules 90 capsules
Declared magnesium 120 mg per capsule 250.5 mg elemental magnesium per three capsules on the updated panel and current PDP
Directions reviewed One to four capsules daily with food Three capsules daily with water, preferably at a meal
What arithmetic can tell you Capsule count changes days per pack within the stated range 90 divided by three gives 30 label-directed daily servings
What arithmetic cannot tell you The appropriate individual daily amount An equivalent Pure regimen or an individual response

Do not manipulate capsule counts to manufacture equivalent regimens. That ignores additional ingredients, directions and individual circumstances; this comparison provides no dose-matching instruction.

The BioEssentials title also uses a 1,950 mg complex figure. That is not the declared elemental-magnesium quantity used in this table. Compound or complex mass cannot replace the magnesium amount printed in the active panel.

Read the Updated BioEssentials Panel

The updated French Supplement Facts panel lists the elemental-magnesium contributions per three capsules as bisglycinate 126 mg, malate 67.5 mg, taurate 24 mg, L-threonate 9 mg and citrate 24 mg. The total is 250.5 mg. The current product page names the same five forms and uses that total.

This comparison uses the updated panel and product page checked on 30 September 2026. The 1,950 mg complex figure describes the combined form mass, not 1,950 mg of elemental magnesium. The listed elemental contributions are label amounts, not a finished-batch laboratory result.

The five listed elemental contributions are not equal. Naming L-threonate does not establish a brain-specific outcome, and naming glycinate on the rival does not establish that everyone will tolerate it in the same way.

Compare the Full Active List

The Pure Supplement Facts panel linked by its current page lists a vegetarian capsule of cellulose and water plus ascorbyl palmitate as other ingredients. Its active table focuses on magnesium. The illustrated and selected pack counts remain distinct, as explained above.

Magnesium 5's French panel adds vitamin D 45 micrograms, vitamin B6 12 mg, zinc 15 mg and black-pepper fruit extract 30 mg per three capsules. These are consequential parts of the choice. They should be reviewed alongside every other supplement already used, rather than treated as automatic bonuses to a magnesium purchase.

The label identifies cholecalciferol, pyridoxine hydrochloride and zinc bisglycinate in the ingredient list. It states manufacture in China for POLARSTAR OÜ. It provides no named allergen declaration that would justify a free-from claim. This comparison makes no certification or allergen-ranking claim for either product; a reader with a specific requirement should obtain current information for the exact pack.

Neither list length wins by itself. Fewer actives can simplify a focused plan; a combined formula requires every added ingredient to be deliberately wanted and suitable.

Read Absorption Studies Within Their Scope

The 1990 citrate-versus-oxide study combined laboratory solubility work with urinary-magnesium measurements after oral magnesium loads in volunteers. Citrate produced a larger urinary response than oxide under the reported conditions. It supports examining the preparation rather than treating every magnesium salt as interchangeable; it did not compare the two branded products in this guide.

The 2003 randomized, double-blind trial compared citrate, amino-acid chelate and oxide preparations in 46 healthy people at 300 mg elemental magnesium daily for 60 days. Several measures favored the organic preparations, with citrate performing differently across the reported endpoints. Its equal elemental amounts are useful study-design context. They do not validate this five-form blend or establish a head-to-head result for Pure MG9 and Magnesium 5.

The 2001 comparison of US commercial preparations reported lower absorption from the tested oxide preparation than from chloride, lactate and aspartate, assessed through urinary-magnesium measures. The authors also noted that some inorganic preparations could perform comparably to organic ones. That prevents a simplistic organic-versus-inorganic sales rule; formulation and protocol still matter.

These studies are relevant to how a comparison is constructed, but absorption-related measurements are not a promise about everyday experience. None provides a current finished-product trial of this exact pair. Both brands face the same evidence boundary: their ingredient names cannot be substituted for a trial of their complete marketed formulations.

Match the Product to the Purchase Question

Reader priority Potentially more practical fit Qualification
Keep the active formula focused on magnesium Pure US MG9 Confirm the pack and review its directions; fewer actives does not guarantee an individual response
Avoid adding B6, vitamin D, zinc or a botanical with magnesium Pure US MG9 The relevant advantage is active-list scope, not a clinical superiority claim
Consider a combined magnesium and co-nutrient formula Magnesium 5 may merit review All co-nutrients must fit the plan; confirm the current market-specific pack
Choose by the highest number of forms Neither can be selected on that basis alone Form count does not establish effective amount, absorption ranking or finished-product outcomes
Buy only after every specification matches Pause any unresolved product decision Apply the same current-pack check to either brand and market

This is where the competitor can fit better: someone seeking magnesium without additional labelled B6, vitamin D, zinc or botanical actives may find Pure's narrower active list more practical. Magnesium 5's potential relevance is the combined formula, conditional on confirming the current pack and reviewing the whole panel. Those are different use profiles, not universal rankings.

Price, discounts, subscriptions and delivery are excluded: no like-for-like transaction was verified. The US and France-facing products have different currency, checkout and delivery contexts.

Complete a Pre-Purchase Check

  1. Match the exact product name, market, capsule count and product code to the pack offered.
  2. Read elemental magnesium together with its capsule or daily-serving denominator.
  3. List every active ingredient and compare it with the supplements already used.
  4. Resolve any disagreement between the current pack, product page and supporting document.
  5. Read warnings and directions before comparing convenience or cost.

Magnesium 5's label reserves it for adults, discourages use during pregnancy or breastfeeding, says not to exceed the daily serving and requires keeping it away from young children. It says supplements do not replace a varied, balanced diet and healthy lifestyle; its L-threonate notice refers to the applicable novel-food regulation. Pure's US page advises professional consultation before use with pregnancy, lactation, a health condition or medication. Neither set of directions should be converted into a personalized regimen here.

Return to the current source for each product before buying. A clear denominator, a complete active list and agreement with the current pack are more useful purchase tools than a form-count contest. Where a detail remains unresolved, preserve the uncertainty and obtain clarification rather than filling the gap with an assumption.

Frequently Asked Questions

Which Pure Encapsulations product is compared here?

The United States Magnesium Glycinate 90-capsule product, professional order code MG9, is the comparator. The official consumer page offers that pack; its linked Supplement Facts illustration shows 120 mg magnesium as glycinate per capsule on a 30-capsule panel, corroborated for MG9 in professional product documentation. Regional labels and other Pure formats are outside this comparison.

Is one Pure capsule equivalent to one Magnesium 5 capsule?

No automatic equivalence is established. Pure reports 120 mg per capsule, while the updated BioEssentials panel lists contributions totalling 250.5 mg for a full three-capsule serving, matching the current PDP. Magnesium 5 also includes vitamin D, vitamin B6, zinc and black-pepper extract.

How much elemental magnesium does the current Magnesium 5 panel list?

The five elemental-magnesium contributions on the updated French panel total 250.5 mg per three capsules: 126 mg from bisglycinate, 67.5 mg from malate, 24 mg from taurate, 9 mg from L-threonate and 24 mg from citrate. The current PDP uses the same total. Confirm the market-specific pack before buying.

Can the cited magnesium studies identify a winner between these products?

No. The studies compare particular salts or preparations using defined protocols and absorption-related measurements. They did not compare the selected Pure MG9 product against the current Magnesium 5 formula.

When might the Pure product be the more practical choice?

It may fit someone seeking a magnesium-only active formula with a clearly stated per-capsule amount and without additional B6, vitamin D, zinc or botanical actives. That practical fit does not guarantee individual tolerance or make its daily label range a personal target.
