How It Works
How It Works
Each capsule delivers 55 billion active probiotic cells across nine gastric-resistant strains that survive stomach acid. These beneficial bacteria colonize your intestinal tract, competing with harmful bacteria while supporting digestive function and immune activity. The proprietary strain blend works together to restore bacterial balance more effectively than single-strain formulas.
Who It's For
Adults recovering from antibiotic treatment that disrupted their gut bacteria. People experiencing acute digestive discomfort who need maximum probiotic support. Health-conscious individuals wanting to maintain optimal intestinal flora during stressful periods.
Who It's Not For
This high-potency formula may be too strong for probiotic beginners — start with lower CFU counts first. Contains milk and soy, making it unsuitable for those with severe allergies to these ingredients.
