<<Disclaimer: Verify this information before applying it to your situation.>> I spent some time at the health food store today looking at digestive aids. I selected a vegetarian product, Vegetarian Digestive Aid by Solgar. It DOES NOT contain corn, yeast, wheat, soy and dairy products and no preservatives, artificial flavors or colors. It contains enzymes for all the food groups (proteins, carbohydrates, fats, etc.) as far as I can determine. Here's the actual enzyme list: Amylase, 40mg Amyloglucosidase, 10mg Lipase, 50mg Prozyme, 25mg Protease, 15mg Cellulase, 4 mg This is in a peppermint sugar-free base. They actually taste pretty good. Happy Digesting! Nancy
