Magnesium Chloride Hexahydrate is a food-grade, high-purity mineral salt used to restore magnesium levels in RO-treated water and support food, beverage, and pharmaceutical formulations. It dissolves faster and more completely than magnesium sulfate, and as a chloride-based salt, offers a sulfate-free alternative where sulfate content needs to be minimized.
Formulated for fast-dissolving, sulfate-free magnesium delivery:
Certified food grade (FCC, E511) for use in food, beverage, and pharmaceutical applications
Exceptionally high solubility (up to 235 kg/100L water) for fast, complete dissolution
High purity (99–105% assay) in a granulated crystalline form for consistent dosing
Stable for up to 3 years when stored in a dry, well-ventilated environment
