I read different online sites by googling enzymes/FODMAP and found information on replacement enzymes. One was Monash University's - FODMAP site and also a few other sites for recommendations. After reading different recommendations that were out there, I went on Amazon's site to look at the cost for these enzymes. Then I read the reviews, both positive and negative reviews. The enzymes that were recommended were very costly but in some of the reviews there were recommendations for other enzymes. One of the products was the one I selected, 'NOW Super Enzymes'. I read what enzymes were in this product and compared them to the more expensive brands. I decided that I would try one bottle for about $10, (90 tablets) - in case I want to cut them in 1/2). If they didn't work, I was willing to try the more expensive ones. I can't believe the difference they have made for me. I just hope that I do not become allergic to any of the ingredients in this product.
I wish you luck and hope that you will also find success in your quest for a solution!
