The Resilience of StableGI® which contains Saccharomyces boulardii

When choosing a probiotic, survival is key. Many beneficial bacteria perish before reaching the gut, but StableGI® whuch contains Saccharomyces boulardii stands apart. This unique probiotic is a yeast, not a bacterium, which grants it natural structural advantages against harsh environments.

The primary secret to its survival is its robust cell wall. Unlike fragile bacterial membranes, the cell wall of S. boulardii is highly resistant to low pH levels. When it encounters the intense acidity of the stomach—often dropping as low as pH 1.5—this yeast remains metabolically inactive but structurally intact.

Furthermore, S. boulardii thrives at higher temperatures, including body temperature, allowing it to rapidly colonize the gastrointestinal tract once it reaches the safety of the intestines. Because it is naturally resistant to stomach acid, it reaches the gut in high concentrations, where it effectively supports digestive health, making it a reliable ally for your microbiome.
