What does ManukaGuard Heartburn do? This liquid blend provides fast relief for occasional heartburn and acid indigestion. With its unique combination of manuka honey and apple cider vinegar, ManukaGuard Heartburn can balance stomach acidity and create a more supportive environment for the microbiome. Low acidity can throw the microflora in the stomach out of balance, hampering digestion and prompting the body to generate more acid to break down undigested food. These swings between low-acid and high-acid states generate stomach pressure, which can lead to heartburn. Balancing the stomach’s microflora ecosystem neutralizes these acid fluctuations, relieving heartburn.
