Hello all
Can anyone tell me if Pancreatin can be replaced with pepsin ?

I just googled it and it listed lipase, protease,amlyase & trypsin as making up Protease. Also seemed that you can buy it at Chemists/health food stores eg. Now foods $17.72 a bottle. Doesn't sound like pepsin alone would do the job, but I don't know for sure.
