IB Synergy™ offers comprehensive support for intestinal health while targeting the brain-gut connection. IB Synergy™ is designed to target the enteric nervous system, the nervous system that controls the GI tract. Considered to be the body’s ‘second brain,’ it is made up of a self-contained, complex network of neurons, neurotransmitters, and proteins embedded in the lining of the GI system. It is responsible for all aspects of the digestive process, from the esophagus to the stomach and small and large intestines, and works to regulate normal digestive activity.
