E511, or magnesium chloride, is a food additive widely used in the food industry as a preservative and stabilizer.
Although magnesium chloride (E511) is considered relatively safe for health when consumed moderately, it is important to remember that an excess of magnesium through additives can cause stomach upset and diarrhea.
Magnesium chloride (E511) is most commonly used in the production of canned vegetables, pickles, cheeses, sausages, and baked goods.
