Is a very important mineral for the body. There are thousands of studies that involve magnesium therapy in some form. These studies evaluate magnesium’s effect on everything from skin health to diabetes and hypertension. Magnesium oil is made from a mixture of magnesium chloride flakes and water. When these two substances are combined, the resulting liquid has an oily feel, but isn’t technically an oil. Magnesium chloride is an easy-to-absorb form of magnesium that may be able to raise levels of this nutrient within the body when applied topically to the skin. The magnesium is absorbed through the skin and is claimed to have health benefits, such as to relieve muscle pains and aches and to enhance relaxation.
