Product Benefits

Proton pump inhibitors are some of the best-selling drugs in the world. But while their use to treat gastic ulcers, H. pylori, and other pathogens can sometimes prove useful over a short period, the long-term side effects are increasingly controversial. According to some studies, their involvement in neurodegenerative processes like Alzheimer’s is significant. Other adverse effects include a disruption of the stomach’s ability to absorb and digest nutrients, inhibition of the production of stomach acid, disorders of intestinal flora, bacterial proliferation of the small intestine, and deficiencies in vitamins and minerals.

The presence of two sources of bicarbonate make it possible to neutralize the excess of acid within minutes of digestion.

Licorice increases the secretion of soothing gastric mucus and decreases that of aggravating pepsinogens. Licorice has gastric antiulcer properties, plays a preventive and curative role against gastric ulcers, and inhibits the adhesion of the harmful Helicobacter pylori (commonly known as H. pylori) bacteria to the gastric wall. Chamomile is also anti-ulcerous and inhibits the production of urease by Helicobacter pylori.

Finally, the mucilaginous Aloe vera gel is healing and anti-inflammatory.
