Soak the day's troubles away and balance body and mind with soothing, rejuvenating magnesium. Life-Flo Pure Magnesium Flakes are highly concentrated crystals of magnesium chloride sourced from the ancient Zechstein Seabed in the Netherlands with nothing added and nothing removed. Found 1,600 to 2,000 meters beneath the Earth's surface, the seabed offers pure, pristine magnesium crystals enriched with trace elements from ancient seawater. One cup of our pure flakes provides approximately 90 grams of magnesium chloride. Pour 1-2 cups into a warm bath (101F to 105F is best) to help relax and refresh overworked muscles and joints, soothe dry skin, and help calm your mind. No time for a bath? Pour some flakes into a warming footbath and soak for a few minutes to revive tired feet and enjoy a quick reset. Our pure magnesium flakes are the real thing with no additives, fillers, or preservatives. Like all Life-Flo products, they are lab verified for purity and potency. Each batch is tested and packaged in our own facility.
