Can I use antacids while on the protocol?

The chronic use of antacids known as proton pump inhibitors (PPIs) may contribute to a relapse of bacterial overgrowth.  The flow of stomach acid into the small intestine is an important barrier to the overgrowth of bacteria within the small intestine. PPI antacids result in a profound reduction of stomach acid production, impairing the acid barrier, thereby allowing the overgrowth of bacteria within the small intestine.n
