Ancient Minerals magnesium comes from the Zechstein Seabed, an ancient sea deep beneath northern Europe, sealed away for about 250 million years and protected from modern pollution. The result is an ultra-pure, naturally sourced magnesium chloride. Magnesium is involved in hundreds of processes in the body, including muscle relaxation, nerve function, energy and restful sleep, yet many people don’t get enough of it from their diet. Soaking in magnesium is a relaxing, easy way to get more. Ways to use it: Relaxing bath: dissolve 1 to 2 cups in a warm bath and soak for at least 20 minutes. Foot soak: dissolve ½ cup in a basin of warm water and soak your feet for 20 to 30 minutes. Homemade magnesium oil: dissolve flakes in equal parts warm distilled water to make your own magnesium spray. It’s a wonderful end-of-day ritual for tired, achy muscles, busy minds and better rest. Good to know: it may leave a slightly slick feeling on the skin, so rinse off after soaking if you like. A mild tingle on the skin is normal. Cautions: for external use only. Avoid applying to broken skin. Talk with your provider if you have kidney disease. Sold by the ounce, so you can try it or refill your supply. Sold by the ounce.
