Magnesium gluconate
Description
Magnesium gluconate (CAS 3632-91-5) is an organic magnesium salt used across food, pharmaceutical, and personal care manufacturing as a bioavailable magnesium source and pH buffer.
Its high gastrointestinal tolerance relative to inorganic magnesium salts makes it a preferred choice for supplement formulators and functional food producers seeking high-quality ingredients.
In dietary supplements and functional foods, it serves as an elemental magnesium carrier in tablets, capsules, and fortified beverages where tolerability and label-friendly positioning matter.
Pharmaceutical manufacturers incorporate it into oral rehydration formulas and magnesium-deficiency therapeutics where consistent purity and controlled release profiles are required for safety.
In food processing, it functions as a pH regulator and stabilizer in dairy analogues, infant nutrition, and processed foods requiring mineral fortification without flavor interference.
Personal care formulators use it as a chelating and buffering agent in skin-conditioning products and mineral-enriched topical preparations to enhance product stability and performance.
Magnesium gluconate is supplied as a white crystalline powder, available in both anhydrous and hydrated forms. Standard grades include food-grade (FCC), USP, and BP/Ph. Eur.
These grades support procurement across regulated pharmaceutical and food manufacturing environments. Packaging typically ranges from kilogram-scale bags to bulk sacks suited for industrial production.
