Are there any dangers associaed with magnesium?

Answer 1

Magnesium is pretty reactive, though like aluminum it's a self-protecting metal: a thin layer of the oxide forms which protects the rest of the metal. However, while it's somewhat difficult to ignite, once it does it burns with an intense heat. At very high serum levels it can cause a range of problems including cardiac arrest, though since it's fairly readily excreted by the kidneys this is usually only a problem for people whose kidneys aren't working all that well.

Answer 2

Magnesium is one of the least toxic metals. Because of it's low toxicity, it is often the metal of choice for applicatons that involve human consumption. Most antacids are magnesium salts, and sacrificial anodes in water heaters are magnesium to prevent more toxic metals from leeching.

Answer 3

Magnesium is an element that is needed in the human diet. It is possible to consume too much of it (as it is possible to consume too much of anything) but that rarely happens. It is much more likely that people will consume too much sodium. Magnesium and its compounds are non-toxic and environmentally benign.

Answer 4

Magnesium is very explosive so accidental explosions are always and issue and if you do not have enough in your body you can have medical issues.

Answer 5

Magnesium is flammable.

It burns very hot and bright and cannot be put out with water or a normal fire extinguisher.
