TummyZen®, is manufactured and marketed by Eli Consumer Healthcare.
Eli was co-founded by a Professor in the Section of Gastrointestinal Surgery at Yale University, Dr. John Geibel, and a long-time heartburn sufferer and entrepreneur, Hasan A. Ansari. Dr. Geibel, who is the Vice Chairman and Professor of Surgery and Cellular and Molecular Physiology, and his lab at Yale have been working for decades on improving understanding of the digestive system – particularly of acid secretion mechanics – in an effort to find a new and better solution for heartburn sufferers.
TummyZen® was born through the serendipitous meeting between Dr. Geibel and Hasan during the latter’s time as a graduate student at Yale. Hasan was so completely blown away by the simple, safe, and effective solution for his own heartburn that he made it his life’s mission to bring this product to heartburn sufferers across America.
