Does apple cider vinegar help SIBO?

While apple cider vinegar (ACV) does not kill SIBO bacteria directly, it can support recovery by acidifying the stomach. Maintaining optimal stomach acid is critical because it triggers the release of pancreatic enzymes and bile, both of which keep the small intestine clean. Furthermore, stomach acid serves as the primary chemical barrier preventing ingested bacteria from surviving and colonizing the small intestine. ACV is best consumed diluted in a glass of water about 15 to 20 minutes before meals to stimulate digestion. However, individuals with active gastritis, stomach ulcers, or severe mucosal inflammation should exercise caution, as the acidity can irritate sensitive tissues.
