Magnesium Chloride vs Magnesium Sulphate


I have been asked many times about the differences between magnesium chloride and magnesium sulphate, commonly known as Epsom Salts. There is a great article a bout it written by Dr Mark Sircus, a well-know and recognised researcher of magnesium and its benefits. I quote it here:


“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.[1] However, Epsom salts are used specifically by parents of children with autism because of the sulfate, which they are usually deficient in , sulfate is also crucial to the body and is wasted in the urine of autistic children.

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. This is a powerful hydrotherapy that draws toxins from the tissues, replenishes the “vital fluid” of the cells and restores cellular magnesium to optimum levels. Magnesium Chloride is environmentally safe, and is used around vegetation and in agriculture. It is not irritating to the skin at lower concentrations, and is less toxic than common table salt.

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 external wounds treatment.

Dr. Jean Durlach et al, at the Université P. et M. Curie, Paris, wrote a paper about the relative toxicities between magnesium sulfate and magnesium chloride. They write, “The reason of the toxicity of magnesium pharmacological doses of magnesium using the sulfate anion rather than the chloride anion may perhaps arise from the respective chemical structures of both the two magnesium salts. Chemically, both MgSO4 and MgCl2 are hexa-aqueous complexes. However MgCl2 crystals consist of dianions with magnesium coordinated to the six water molecules as a complex, [Mg(H2O)6]2+ and two independent chloride anions, Cl-. In MgSO4, a seventh water molecule is associated with the sulphate anion, [Mg(H2O)6]2 +[SO4. H2O]. Consequently, the more hydrated MgSO4 molecule may have chemical interactions with paracellular components, rather than with cellular components, presumably potentiating toxic manifestations while reducing therapeutic effect.”

MgSO4 is not always the appropriate salt in clinical therapeutics. MgCl2 seems the better anion-cation association to be used in many clinical and pharmacological indications.[2] Dr. Jean Durlach et al

Magnesium sulfate is a chemical compound containing magnesium and sulfate, with the formula MgSO4. In its hydrated form the pH is 6.0 (5.5 to 7.0). It is often encountered as the heptahydrate, MgSO4·7H2O, commonly called Epsom salts. Anhydrous magnesium sulfate is used as a drying agent. Since the anhydrous form is hygroscopic (readily absorbs water from the air) and therefore harder to weigh accurately, the hydrate is often preferred when preparing solutions, for example in medical preparations. Epsom salts have traditionally been used as a component of bath salts.

Oral supplementation is probably the first one most of us will think of. However, not all of us can absorb oral magnesium efficiently, especially if the digestive system is clogged up with impurities, or is not very efficient – which is true of the majority of the world population over the age of 30. Even when it is healthy, much of magnesium we take orally passes through the body unabsorbed, and if we take too much then even less of it will be absorbed, since it is a laxative.

This makes transdermal magnesium supplementation a much more suitable option for most people. Transderamlly, magnesium gets into the cells – where it is most needed – very quickly.

The most popular ways to supplement magnesium transdermally is a bath, a spray, or a massage. Body spray and massage are most economical ways to do it. Just spray or massage the body with magnesium oil once a day after a bath or a shower. Leave it on for 1 hour, or even overnight if you can, and you should feel the relaxing and tension relieving effects of magnesium very soon.

Transdermally, magnesium can also be administered in baths, foot baths and compresses. For a bath I suggest using magnesium flakes as the more economical way to achieve the best concentration. Use about 500g of magnesium chloride flake in a bath, and 250g in a foot bath. Such procedures are most beneficial before bed time, since deep relaxation resulting from and increase of magnesium in the body will certainly promote sleep.


This is an amazingly relaxing and therapeutic treatment which I have developed recently. It is aimed at those who are desperately deficient in magnesium and need quick supplementation. The treatment uses far-infrared heat to open up pores and boost circulation not only in the skin, but in deeper body structures. With the pores open and blood flow increased, magnesium stands a better chance to be absorbed quickly and in large quantities.

The treatment is preceded by a massage to stimulate circulation and soften up the tissues. The infrared heat helps open up the cell membranes, which contributes towards magnesium absorption.

Apart from being very therapeutic, the treatment is thoroughly relaxing, thanks to the effects of magnesium and the infrared heat. It promotes detoxification on the cellular level, helps to relieve aches, pains, muscle spasms, arthritis, sleep problems, fatigue, boost immunity, promote relaxation, help relieve water retention and is a really great start to a weight loss programme. People generally lose a lot of water during the treatment which has an added physical effect of feeling lighter afterwards.

One of my customers described the way she felt during the treatment as “wrapped in a soft cocoon”, and another said that it felt “like being in a mother’s womb waiting to be born”.
