- ZINC L-CARNOSINE: The chelated form that specifically supports the protective mucus layer of your digestive tract.
- TARGETED PROBIOTICS: BB536 and S. boulardii strains chosen for digestive health, not just generic gut bacteria.
- CHAMOMILE EXTRACT: 4:1 concentrated extract provides natural soothing support for occasional digestive discomfort.
