Epsom salt, chemically known as magnesium sulfate, is a naturally occurring mineral compound valued for centuries for its therapeutic properties. Despite their similar appearance, the key difference between medical grade and food grade Epsom salts lies in their purity and the strict regulations they must meet for their intended use. While both are high-purity forms, only medical/pharmaceutical grade (USP) is approved for all internal and medical applications, whereas food grade (FCC) is safe for specific dietary and food processing roles.
