What it is

Magnesium chloride hexahydrate is a form of magnesium chloride, a salt made from magnesium and chlorine. It is often produced by reacting magnesium hydroxide or magnesium oxide with hydrochloric acid. It appears as white crystals and is soluble in water.

Why it's used

Manufacturers add magnesium chloride hexahydrate to foods as a source of magnesium, which is an essential mineral. It is also used as a firming agent and to add a salty or bitter taste. It is commonly found in sports drinks, electrolyte beverages, and some plant-based waters.

Health notes

Magnesium chloride is Generally Recognized As Safe (GRAS) by the FDA for use in food. Magnesium is an essential nutrient involved in many bodily functions. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated magnesium chloride and set an acceptable daily intake. High doses of magnesium from supplements or medications can cause diarrhea, nausea, and abdominal cramping, but these effects are unlikely from typical food sources.

Allergen info

Not a major allergen. It is not derived from any of the 9 FDA major allergens, nor does it contain gluten.
