Magnesium Bath Flakes are made from Magnesium Chloride, Epson Salts are made of Magnesium Sulfate.1

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 metabolised in the human body.2 However, Epsom Salts are especially useful and used specifically by parents of children with autism because of its sulfate content, which the children are usually deficient in. Sulfate is also crucial to the body and is wasted in the urine of autistic children, thus, it is a great idea to rebalance their body.

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.3

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 Ssulfate 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. 4
