At Cogent Solutions Group, Aspergillus oryzae (A.O.) has been created by our parent company, BioZyme® Inc., using a proprietary, multi-step process that has been refined over the last 70 years. AO-Biotics® Amaferm®, found in Baxyl-GI, is a prebiotic research-proven to enhance digestibility, while supporting a healthy gut microbiota. With 70% of the immune response found in the digestive tract, a prebiotic like AO-Biotic Amaferm helps improve your overall health. There are numerous varieties of AO found in food and health products, however, when we refer to AO, we are talking about our proprietary strain.
