Digestive bitters (gentian, artichoke, dandelion, etc.) activate bitter taste receptors (T2Rs) in the gut — yes, your GUT has taste receptors. T2R activation stimulates: gastric acid secretion, bile flow (choleretic), pancreatic enzyme release, and GLP-1 secretion. The mechanism was validated when T2R receptors were identified in enteroendocrine cells in 2003. Bitters before meals improve digestion through this physiological reflex. Iberogast® (9-herb bitter formula) is the most-studied product: reduced functional dyspepsia symptoms by 68% in a 2004 RCT. Traditional but with genuine mechanistic basis. --- *Reviewed by the Dose AI Research Team and Clinical Advisory Board* *Last updated: 2026-04-06*
