The short answer is no, our Digestive Enzymes DO NOT include yeast, mold, or any other microbial organisms. 


Some of our Enzymes are microbial-based, while others are plant-based. The plant-based ones include bromelain from pineapple and papain from papaya. Most enzyme products are microbial-based, specifically bacterial or fungal. After the enzymes are grown and multiply in a culture, they are then separated from the microbes through a rigorous micro-filtration process. This filtration process removes all impurities, proteins, and microbes, leaving only the enzymes. So while the enzymes are derived from microbes, they are microbe-free after this thorough micro-filtration process.
