What Is Magnesium Pidolate? Identity and Elemental Magnesium for Formulators

What is magnesium pidolate? It is a magnesium salt made with pidolic acid, which is also called pyroglutamic acid. The salt supplies magnesium, but most of its weight comes from the other parts of the compound. This difference matters when you work out how much powder your capsule or drink mix needs.

At Maxmedchem, we manufacture and supply magnesium pidolate powder for supplement formulation. We recommend writing the ingredient identity and the elemental magnesium amount as two separate fields in the product brief. Your buyer can then request the right material, and your lab can calculate how much of that material belongs in the batch.

What Is Magnesium Pidolate on a Chemical Specification?

Match the name, CAS number, and formula

PubChem’s compound record identifies magnesium pidolate under CAS 62003-27-4. It gives the molecular formula C10H12MgN2O6 and a formula mass of 280.52 g/mol. The record describes a salt with two pidolate units for each magnesium ion. You may also see the name magnesium 2-pyrrolidone-5-carboxylate.

Use the full identity to check a supplier quote. If one document says only “organic magnesium” and another says magnesium pidolate, ask the seller to confirm what it will ship. If the grade contains a carrier or a second source of magnesium, get the complete composition. The certificate, shipping label, and purchase order should all point to the same material.

Tell the difference between formula identity and commercial grade

A chemical database describes a substance. It does not describe the water content, particle size, or contaminant results of a shipment. Two lots can share a CAS number and still behave differently on a capsule line. Ask for a technical data sheet and a lot certificate rather than using a database entry as a purchasing specification.

Ask the formulator which physical details matter. A powder blend may need information on particle size to help keep it uniform. A capsule trial may need bulk density and flow data. A drink prototype may need a dispersion check. Put those needs in the brief before you approve a sample.

What Is Magnesium Pidolate Worth in Elemental Magnesium?

Work through the chemical calculation

Magnesium has an atomic mass of about 24.305 g/mol. Divide that by the salt formula mass of 280.52 g/mol and multiply by 100. The result is about 8.66% elemental magnesium in the pure anhydrous salt. This describes the share of mass made up by magnesium atoms. It does not describe how much magnesium a person absorbs. PubChem atomic masses.

For a simple example, 500 mg of pure anhydrous magnesium pidolate corresponds to about 43.3 mg of elemental magnesium. If an actual lot tests at 8.50% by mass as received, 500 mg of that lot contains 42.5 mg. Use the second calculation for that lot. Save the method and assay basis next to the number on the batch sheet.

Give the label reviewer the same units as the lab

The FDA supplement nutrition labeling guide explains how to declare mineral amounts and sources on U.S. supplement labels. Keep the elemental magnesium per serving separate from the mass of pidolate powder in the formula. Confirm how the source should appear on the final label in your target market.

Use the full serving when you review the numbers. A serving could contain more than one capsule. It could also contain magnesium from more than one input. Add the contribution of each verified source. Ask your label reviewer to check rounding and the declared amount after your lab reviews the actual formula.

What Is Magnesium Pidolate Like in a Pilot Formula?

Start by testing what you can observe. Weigh the sample, check how it moves through the intended process, and see whether the dose fits the format. A grade can meet the chemical specification and still need a different fill setup. Your test should use the complete blend with the same excipients and pack you intend to sell.

For a dry blend, take samples at defined points and ask the lab to check whether the mineral is evenly distributed. For a drink, use the proposed water volume, temperature, and mixing method. Note the taste and any settling after the time a customer is likely to wait. Those observations help the formulator choose a direction before ordering a commercial amount.

Track any change after storage. Powder can handle differently after a pack has been open or after it has spent time in a different environment. Record the conditions and compare the results with your limits. If you see a difference, check whether it came from the powder, the rest of the formula, or the pack before changing suppliers.

An important early check is whether one serving can fit the package without an awkward instruction. If the calculated powder mass is too large for the planned capsule, measure actual blend fill before changing the nutrient target. A two-capsule serving or a stick pack changes both the user experience and the budget. It may be a better choice, but it deserves its own estimate.

Decide how the pilot will distinguish a raw material issue from a process issue. Compare a reserve sample from the same lot with material pulled from the line. If the two behave differently, check handling and storage before blaming the supplier. If both behave differently from the prior lot, compare their test records and physical properties. Those comparisons are only possible when your team kept the lot numbers and conditions.

Do not confuse an element test with a compound test. Two samples with the same magnesium percentage can contain different salts or blends. Likewise, a matching identity does not guarantee that two lots have the same elemental content by weight. Ask the lab to explain what each test establishes and where you still need another check.

For a project that needs several deliveries, record which pack is approved and how it will be stored after receipt. The same material in a different liner or container may need a review of handling and storage. Agree on the change notice before you place the order so the warehouse can identify a difference at receiving.

What Is Magnesium Pidolate in a Supplier Qualification File?

Ask for a representative sample, a current specification, a technical data sheet, and a certificate for the specific lot. Include the test method and reporting basis for elemental magnesium. Ask which tests verify the compound identity and which address limits for contaminants. Give the quality team room to define its own incoming checks.

State the target grade and planned order quantity on the request for quotation. Ask about wholesale pricing, minimum order, pilot sample lead time, pack size, and delivery to your site. Confirm whether the quote covers the testing and pack you need. Compare the offers using the same units rather than comparing total bags from different grades.

Our view is that a good raw material file answers three questions quickly. Can you identify it? Can you calculate the serving from the lot result? Can your line use it consistently? If any answer is missing, put that check into the pilot. Our supplement ingredient catalog and manufacturing profile can help you identify other inputs and plan the order.

Request a magnesium pidolate sample and a bulk quote. Contact Maxmedchem with the target market, format, required assay, pilot size, and commercial volume. Ask for the current technical and lot documents before you set a release date.

FAQs

Is magnesium pidolate the same as magnesium pyroglutamate?

Magnesium pyroglutamate is a name used for this salt. Match the exact chemical identity and grade in your documents.

What is its CAS number?

PubChem lists 62003-27-4 for magnesium pidolate.

How much magnesium is in the pure salt?

The formula gives about 8.66% by mass for pure anhydrous material. Use the tested result for the commercial lot.

Is 500 mg of pidolate the same as 500 mg of magnesium?

No. At the theoretical elemental fraction, 500 mg of pure anhydrous salt contains about 43 mg of magnesium.

What should I verify first when buying bulk powder?

Verify identity, elemental assay and basis, lot traceability, and fit with the planned format.
