Magnesium Sulfate Heptahydrate

Magnesium Sulfate Heptahydrate (MgSO₄·7H₂O) – Feed & Fertilizer Grade

Product Overview

Magnesium Sulfate Heptahydrate (MgSO₄·7H₂O) is a high-purity, water-soluble mineral compound derived from natural magnesite. Known for its monoclinic crystal structure and full solubility in water, it serves as an essential magnesium and sulfur source for animal feed, fertilizers, and various industrial applications. Free from heavy metals and toxic impurities, it provides bioavailable magnesium to improve metabolic efficiency, enzyme activation, and chlorophyll formation in both plants and animals.
