Yes they actually sell "digestive enzymes" as supplements. There are many formulas that are mixtures that will help to digest everything.
This includes amylase which digests carbohydrates, lipase which digests fat, and protease which digests protein. Bromelain and papain (enzymes from pineapple and papaya, respectively) are also supposed to help digest protein. So you could take a mixture of some or all of the above. Hope that helps you.
