I think one could benefit from experimenting with the different types of enzymes instead of only ever giving them in a given combination. Unfortunately, I have not yet found any such product commercially. I found a product only containing cellulase (to help fibre digestion) but the company only replied to me that they do not sell it for personal use: http://www.creative-enzymes.com/common/Digestive-Enzymes-Cellulase_2_50.html. On http://www.enzymestuff.com/basicsenzymeguide.htm it is mentioned that 'speciality products' (as opposed to the 'all in one enyme products' that keep on coming up on my searches) do exist...
