I have been experimenting with various probiotics for different GI issues (fairly constant heartburn and also lower intestinal pain). It seems I can find probiotics to deal with one issue, or the other, but not both at the same time.
Recently, I started taking the probiotic Align. I open the capsule and just take a small amount daily....such that once capsule lasts me for about a week. I was surprised to find that my heartburn has eased substantially. I hardly notice it now. Maybe it would help you?
I did try the D-Limone (it's been awhile). That didn't seem to work. The George's aloe has been on my list to try, but right now I'm decently happy with the Align. However, it is not helping the lower GI pain, so I may try to add in the probiotics that did help with that and see what happens if I take a small amount of all 3 of them.....
Wishing you success!
