What are the symptoms of magnesium deficiency?

Magnesium is an ingredient found in many treatments for acid reflux. Antacids frequently combine magnesium hydroxide or magnesium carbonate with aluminum hydroxide or calcium carbonate. These mixtures can neutralize acid and relieve your symptoms.Magnesium deficiency does not cause low stomach acid. Rather, low stomach acid can be a factor in magnesium deficiency. One third to 1/2 of the magnesium found in foods is absorbed by the body in the small intestine. Foods high in sugar and fats are difficult for the stomach to digest.
