Mechanism of action

Its effectiveness in improving stool consistency is the result of its ability to absorb bacteria, viruses and toxins as well as strengthening the intestinal mucus barrier to reduce luminal antigens passing through the mucus barrier which in turn helps to reduce inflammation.[1]
