Wholesale Epsom Salt USP Grade (Magnesium Sulfate) — Bath, Foot Soak & Garden

Greenway Biotech Epsom Salt is pure USP-Grade magnesium sulfate heptahydrate (MgSO4·7H2O) - the same pharmaceutical-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. Beyond the bathtub, the same bag works in the garden as a fast-acting source of magnesium and sulfur for plants showing confirmed magnesium deficiency - tomatoes, peppers, roses, citrus, and leafy greens are the most common responders. Available in 2 lb, 5 lb, 10 lb, and 25 lb resealable bags. 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. Backed by a 90-day money-back guarantee.
