Magnesium bicarbonate is a form of water with high amounts of magnesium and bicarbonate ions. It contributes to your daily magnesium needs and supports a healthy pH level by increasing bicarbonate intake. Magnesium bicarbonate is the ultimate form of magnesium and the best form of bicarbonate. Super absorbable is the only way to describe magnesium bicarbonate water. Many forms of magnesium are not very bioavailable, which means you have to take more to get enough. Magnesium bicarbonate is absorbed into the bloodstream with water directly through the small intestine. Ethan Evers, in his book The Eden Prescription, says, "Magnesium (Mg) in drinking water has a higher impact than that in food because it has hydrated ions which are absorbed very efficiently (only about half of Mg from food is absorbed). Also, food cooked in Mg-rich water loses less of its own Mg during cooking.
