Greenway Biotech Epsom Salt is pure magnesium sulfate heptahydrate (MgSO4·7H2O), repackaged from USP-grade raw material - the same purity specification used for pharmaceutical excipients. Fine-grain crystals dissolve quickly in warm water with no stirring or gritty residue, making it well suited to relaxing bath soaks, foot soaks, and DIY body scrubs.
Available in 1, 3, 5, 10, 20 and 25 lb bags, or two 25 lb bags. For garden, lawn and hydroponic use, see our Epsom Salt for Plants.
Sourced within the United States and packaged at our family-owned Madera, California facility - registered with the FDA. Third-party lab tested and screened for heavy metals; results consistently well below required limits. 100% magnesium sulfate with no added fragrance, dye, filler, or preservative. External use only.
