Magnesium Oil is in fact not oil, but rather a saturated salt solution made of 69% water and 31% magnesium chloride, which has an oily feel. Every molecule of magnesium chloride binds six water molecules. This property means the magnesium chloride stays permanently wet, which supports its absorption through the skin. Magnesium Chloride is primarily produced from seawater. Because of increasing oceanic pollution, such magnesium salts need to be refined, causing the loss of other co-occurring minerals. The result is an artificial and processed product. Our magnesium chloride comes from an ancient dried up Zechstein Sea where salts are protected from any pollution on the surface. So, we ensure a 100% money-back guarantee for our quality-conscious customers within 30-days of purchase.
