This was recommended by our doctor to try to help with GERD symptoms. The hope is that it will heal the gut vs just treating the symptoms. My husband has only been taking it for 2 weeks, so it's too early to tell. The first week, his symptoms seemed to be under control, but this week hasn't been so good. However he did eat some things that we learned was not good to eat if you have GERD. It's a learning process to figure out what your triggers are. I was a little disappointed that the supplement didn't protect his stomach better, but again it's only been a couple of weeks… our doctor said that this has been helping many people… we are hoping it will work for him also. I gave it 4 stars because it came highly recommended for our doctor. I will change my rating to 5 stars if it works for my husband…
