What is Magnesium Chloride?

Magnesium chloride is the name for the chemical compounds with the formulas MgCl2 and its various hydrates MgCl2(H2O)x. These salts are typical ionic halides, being highly soluble in water. The hydrated magnesium chloride can be extracted from brine or sea water. Our Magnesium Chloride comes from the Dead Sea where its healing benefits have been utilised for literally hundreds if not thousands of years. Our small white flakes of magnesium chloride hexahydrate (MgCl2.6H2O) have a MgCl2 content of 47% (well above that of Epsom Salts) and are ideal for use transdermally (i.e., acting across the skin surface). Transdermal application allows the body to absorb as much magnesium as it may require. Unlike oral magnesium supplementation (which is characterized by certain limits on the rate and amount of uptake and assimilation), magnesium applied directly on skin via baths or footbaths (i.e., transdermal application) can rapidly and effectively raise tissue (and cellular) levels of magnesium. Topical application of dissolved magnesium flakes (e.g., in a bath) simultaneously provides energy and relaxes muscles. This means users will be primed for peak performance, being relaxed and energized. Users also report deeper, more restful sleep, reduced stress, and greater well being. There are a large number of uses for Magnesium Chloride so please don't hesitate to get in touch if you have any questions.

Magnesium Chloride Applications

Magnesium Chloride Hexahydrate is an all natural product with an incredible number of uses:


  • Health & Beauty: Magnesium baths, foot soaks, wound applications, etc. As well as having numerous health benefits Magnesium Chloride Hexahydrate promotes restful sleep, performance, energy, relaxation and general wellbeing.

  • Agriculture & Farming: Used commercially as a fertilizer, animal feed supplement, dust suppressant and for de-icing purposes.

  • Building & Industry: Used for creating oxychloride cement, so-called Sorel cement. As a dust suppressant on building sites. In the creation of magnesium metal, certain textiles and detergents. In drilling operations and cooling systems.

  • Dust Control: The hygroscopic nature of Magnesium Chloride flakes makes it a preferred dust suppressant on roads, building sites, farm yards, mines and other dusty environments.

  • De-Icing: Interestingly, magnesium chloride is one of the world's more popular de-icing agents. It can be applied after ice has formed, to remove ice buildup from roadways, driveways and sidewalks.

  • Damp Suppression: Placed in open containers Magnesium Chloride removes damp from the environment.

  • Aquariums: An ingredient in artificial seawater.


Magnesium Chloride Detoxifying Baths

For purposes of cellular detoxification and tissue purification, the most effective form of magnesium is magnesium chloride, which has a strong excretory effect on toxins and stagnant energies stuck in the tissues of the body, drawing them out through the pores of the skin. Chloride is required to produce a large quantity of gastric acid each day and is also needed to stimulate starch-digesting enzymes.


According to Daniel Reid, author of The Tao of Detox, magnesium sulfate, commonly known as Epsom salts, is rapidly excreted through the kidneys and therefore difficult to assimilate. This would explain in part why the effects from Epsom salt baths do not last long and why you need more magnesium sulfate in a bath than magnesium chloride to get similar results. Magnesium chloride is easily assimilated and metabolized in the human body. In addition to its functions as an electrolyte, chloride combines with hydrogen in the stomach to make hydrochloric acid, a powerful digestive enzyme that is responsible for the breakdown of proteins, absorption of other metallic minerals, and activation of intrinsic factor, which in turn absorbs vitamin B12. Using other magnesium salts is less advantageous because these have to be converted into chlorides in the body anyway. We may use magnesium as oxide or carbonate but then we need to produce additional hydrochloric acid to absorb them. Many aging individuals, especially with chronic diseases who desperately need more magnesium, cannot produce sufficient hydrochloric acid and thus cannot absorb the oxide or carbonate. Chloride is a highly important and vital mineral required for both human and animal life. Without chloride, the human body would be unable to maintain fluids in blood vessels, conduct nerve transmissions, move muscles, or maintain proper kidney function. As a major electrolyte mineral of the body, chloride performs many roles, and is rapidly excreted from the body. Magnesium chloride solution was not only harmless for tissues, but it had also a great effect over leucocytic activity and phagocytosis; so it was perfect for treatment of external wounds. – Dr. Jean Durlach


For Storage - Magnesium Chloride draws water from the air and turns to liquid. Therefore we recommend you store your Magnesium Chloride in a non metallic airtight container upon receipt of your shipped product.
