Since 2007 when Mark Sircus published his book "Transdermal Magnesium Therapy", Magnesium oil has been in high demand and for good reasons. In Mark Sircus book on Transdermal Magnesium Therapy, he highlights that "magnesium is the single most important mineral for maintaining proper electrical balance and facilitating smooth metabolism in the cells". Magnesium deficiency is wide spread and in this book Mark Sircus explains that the majority of the population are magnesium deficient. And its highly likely that you know someone suffering from a related disease or illness. On page 36 he explains: "transdermal magnesium, which involves absorbsion directly through the skin, is inexpensive, safe, a do it yourself at home technique". Also "By using what is called Magnesium oil, either topically or in a soak, massive amounts of magnesium can be absorbed naturally, by our bodies". He also adds, "Transdermal application of magnesium (oil) is actually superior to oral supplements in many ways".
Without doubt, supplementation of magnesium oil applied topically whether directly to the skin or in a bath soak, is the best way to absorb magnesium, but what is the best best form or type of magnesium oil.
First of all, magnesium oil is not an oil, its a highly saturated solution magnesium chloride in water. It is called magnesium oil due to its slippery feel on the skin and unlike oils it is fully absorbed and does not leave any residue on the skin.
There are two types of magnesium oil that can be purchased, ocean sourced magnesium chloride and ancient mineral magnesium chloride deposits. There are many concerns over the ocean sourced magnesium oils, mainly due the array of pollutants that are found in today's oceans. The best type of magnesium oil that can be purchased is magnesium oil from deep under ground, sourced 1500 to 2000 meters below, from the ancient Zecstein Seabed located below northern Europe. Naturally protected from modern chemicals/pollutants the zechstein magnesium oil is ultra pure and does not need high refining methods commonly used with ocean sourced magnesium oils. Purity is key.
