Frequently Asked Questions About Epsom Salt
Is all Epsom salt the same?
All Epsom salt contains the naturally occurring minerals of magnesium and sulfate. There are different ways of manufacturing and packaging Epsom salt, but chemically, it’s all exactly the same. There are also different “grades” of Epsom salt for different applications such as human use and agricultural applications.
Any package that has a “drug facts” box or that’s labeled “USP” has been manufactured, tested and certified to meet stringent regulatory standards of the FDA and the United States Pharmacopeia, and is deemed safe and acceptable for human use. For human use, the Epsom Salt Council recommends only Epsom salt with the USP designation.
