THE UTLRA FLAKES DIFFERENCE AND OPTIMSM: OptiMSM bath flakes contain the same high potency magnesium chloride concentration as our best-selling flakes, but also contains elemental sulfur that provides added benefits including joint and immune health support. Without sufficient MSM sulfur, your body cannot maintain an appropriate level of homeostasis and OptiMSM has earned the reputation for the purest, safest, and most consistent MSM in the world. | WHY CHOOSE MAGNESIUM FLAKES VS EPSOM SALT: Bath flakes are made from magnesium chloride. Epsom salts are magnesium sulfate. Although both contain a form of magnesium, magnesium chloride is much better suited for topical application and absorption. Flake Baths are great for stress relief, muscle aches and soreness improving circulation, restoring cellular levels, relieving headaches, joint pain, and much more. | ONLY THE PUREST & HIGHEST CONCENTRATED MAGNESIUM SOURCES: Genuine Zechstein magnesium chloride, sourced from 1500 meters underground the ocean and 250 Million years in the making, is the purest magnesium source in the world. Our MSM is sourced from Bergstrom Nutrition who uses proprietary distillation and purification techniques to make the purest MSM in America. | MAGNESIUM BODY WASH APPLICATION INSTRUCTIONS: Dissolve 1-3 cups of flakes into a warm footbath or full tub, and soak for 30 min or longer. Dissolve up to 8lbs of magnesium flakes in a full body immersion for intense application. Temperature of the water should be warm, but not hot. Hot water can cause the skin to eliminate mag chloride vs absorb magnesium. Each cup of ULTRA bath flakes dissolved contains 15g of elemental magnesium and 3g organic MSM sulfur. | #1 TRUSTED NAME IN CONCENTRATED TOPICAL MAGNESIUM PRODUCTS: Since 2007 Ancient Minerals by Enviromedica, has produced the highest quality topical flakes, essential oil, goodnight lotion, miracle cream, and aloe vera gel magnesium.
