Magnesium sulfate sanderite are rare. Kieserite is a monohydrate and is common among evaporitic deposits. Anhydrous magnesium sulfate was reported from some burning coal dumps. Double salts containing magnesium sulfate exist, for example there are several known sodium magnesium sulfates and potassium magnesium sulfates. An abnormally elevated plasma concentration of magnesium is called hypermagnesemia. Magnesium sulfate Magnesium sulfate is an inorganic salt with the formula MgSO(HO) where 0≤x≤7. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO·7HO), commonly called Epsom salt. The overall global annual usage in the mid-1970s of the monohydrate was 2.3 million tons, of which the majority
Magnesium citrate 11.23% magnesium by weight. Compared to trimagnesium citrate, it is much more water-soluble, less alkaline, and contains less magnesium. As a food additive, magnesium citrate is used to regulate acidity and is known as E number E345. Magnesium citrate works by attracting water through the tissues by a process known as osmosis. Once in the intestine, it can attract enough water into the intestine to induce defecation. The additional water stimulates bowel motility. This means it can also be used to treat rectal and colon problems. Magnesium citrate functions best on an empty stomach, and should always be followed with
