The sodium phosphate in our digestive tracts breaks down stomach acids and regulates bile. When overwhelmed by fatty, bitter or sugar-filled foods and beverages, including alcohol, the body cannot make enough sodium phosphate to handle all the stomach acids needed for digestion. As a result, we get acid symptoms like heartburn, diarrhea, gas, sour belching, and a yellow coating on the back of the tongue. In babies, Nat phos is a very natural gentle way to relieve colic, sour vomiting, and sour smelling green diarrhea. In children, Nat phos can ease the crash and headaches of sugar highs. As a safe source for heartburn relief during pregnancy, Nat phos is irreplaceable. Top of the head headaches and sick headaches with sour vomiting find relief in it whether due to morning sickness, dietary excesses or illness.
