Most antacids work by neutralizing the stomach acids so it doesn't “burn” if they get into the esophagus. Unfortunately, the stomach just responds by producing more acid, to avoid delaying digestion, and thus sets up a vicious circle. This does not happen with Frutin because the neutral dolomite/ pectin foam rises to the top of the stomach, keeping the acid in the stomach where it belongs. This soft foamy “lid” stays in place for up to 5 hours, allowing digestion to proceed normally, with no acid reflux effect. Frutin also quickly neutralizes any acid that may have already reached the top of the esophagus, easing discomfort quickly.
