Magnesium Gluconate is a food-grade magnesium salt of gluconic acid, a white to off-white powder widely used as a highly bioavailable magnesium source in dietary supplements, sports nutrition, and medical foods.We supply bulk Magnesium Gluconate sourced from leading China manufacturers, available in powder form for global food and beverage producers. Our Magnesium Gluconate is widely used in dietary supplements, electrolyte formulas, iV therapy solutions, chewable multivitamins and energy drinks.
Magnesium Gluconate is manufactured by the neutralisation of gluconic acid with magnesium carbonate or magnesium oxide, followed by crystallisation and drying.
It meets USP, EP, FCC and BP specifications and is classified GRAS by FDA. Its high water solubility and neutral taste make it ideal for liquid and effervescent mineral supplement formats.
