    It appears to be pretty low toxicity.

    Magnesium chloride - Wikipedia, the free encyclopedia
    Magnesium ions are bitter-tasting, and magnesium chloride solutions are bitter in varying degrees, depending on the concentration of magnesium.

    Magnesium toxicity from magnesium 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.

    Just to add to the information Strange has provided, there is a fair amount of MgCl₂ in seawater, almost 10% of the amount of NaCl I think.

    Thank you. Can Magnesium Chloride be used as the source of the human intake of trace element magnesium when it is used as food additive?

    Thanks for your answer, but does the Magnesium Chloride belong to industry grade which is extracted directly from seawater?

    It could be one source. Most foods contain magnesium, though, and most people get all they need from their diet (humans need about 200mg per day). The body is apparently, very efficient at getting magnesium from foods and will even recycle it. So magnesium deficiency is pretty rare. Apparently it can occur in the elderly and alcoholics.

    Some beers contain a lot of magnesium.

    My book just says "a sizeable proportion" of magnesium is extracted from seawater (as opposed to mineral ores). I assume that means less than half. 30% comes from the USA followed by Russia and Canada - together they account for more than half the world's production. (That could be out of date, I suppose).

    Wow. Totally out of date. According to the U.S. Geological Survey's 2011 Minerals Yearbook China now produces 80% of the world's magnesium.

    Thank you so much for your answer. I have to say your answer is really great, and thank for immediate updating your answer, which is of great help to me!
