Do stomach acids destroy pancreatic enzymes?
No, pancreatic enzymes from vegetarian sources make it through the digestive process quite well. Unlike animal origin enzymes, vegetarian enzymes have a broader pH range of action, supporting break down of food in both your acidic stomach (pH about 3.0) as well as your more neutral intestines (pH about 6.0). This means there is no need for enteric coating, which adds both cost and extra chemicals to any formula.
