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!
