Prelief is a safe, effective over-the-counter product that removes the acid irritant from foods and beverages. Prelief helps prevent the discomfort of food-caused heartburn and other food acid problems before they happen. Prelief is the only acid fighter that is designed to take irritating acids out of the foods you eat, while leaving your protective stomach acid untouched. This is important because stomach acid is essential to both your digestion and your body's defense mechanism against bacteria; stomach acid is actually a first stop in the bodys germ-defense system.
