What is Magnesium Gluconate CAS 3632-91-5?

Magnesium Gluconate, also called magnesium D-gluconate, is the magnesium salt of gluconic acid with the formula C12H22MgO14 on an anhydrous basis. It is a water-soluble mineral salt used as a bioavailable magnesium source.

Is Magnesium Gluconate supplied as an anhydrous product or a hydrate?

Commercial magnesium gluconate is commonly supplied as a hydrate, while its formula and assay are usually expressed on an anhydrous basis. The amount of water of hydration can vary, so specification sheets should be used for exact content and dosing.

How does Magnesium Gluconate compare with inorganic magnesium salts?

It is freely soluble in water and generally has a milder taste than many inorganic magnesium salts, making it suitable for foods, beverages, and oral supplements. Because the gluconate anion has a higher molecular weight, its magnesium content by weight is lower than that of magnesium oxide or sulfate.

Which applications benefit most from Magnesium Gluconate?

It is especially useful where clean solubility, mild flavor, and compatibility in aqueous systems are important. Typical uses include dietary supplements, fortified foods and beverages, pharmaceutical oral dosage forms, and soluble mineral blends.

What grades are available for Magnesium Gluconate?

The grade depends on the intended end use. Food-grade/FCC and pharmaceutical grades such as USP or BP/Ph. Eur. are common, with assay, heavy metals, and microbial limits matched to the selected application.
