Magnesium chloride salts is rare in healthy individuals with a normal diet, because excess magnesium is readily excreted in urine by the kidneys. A few cases of oral magnesium toxicity have been described in persons with normal renal function ingesting large amounts of magnesium salts, but it is rare. If a large amount of magnesium chloride is eaten, it will have effects similar to magnesium sulfate, causing diarrhea, although the sulfate also contributes to the laxative effect in magnesium sulfate, so the effect from the chloride is not as severe. Chloride (Cl) and magnesium (Mg) are both essential nutrients important for normal
Hydrated silica an odourless, tasteless, white, gelatinous substance, which is chemically inert. Chemical Formula: SiO · HO Diatomaceous earth, originally mined as "tooth powder" is a naturally occurring hydrated silica. As a fine gel abrasive, frequently combined with softer calcium carbonate (from chalk) it helps to remove plaque. Milled to a slightly larger size, the grains are more aggressive and are used in tooth bleaching formulations. It also has synergetic effects when compounded with traditional flame retardants such as magnesium hydroxide and aluminium hydroxide. Hydrated silica is listed by the US Food and Drug Administration as "Generally Recognized as Safe". Toothpaste: Chemistry:
