I've been giving my son Turmeric root (contains curcuminoids) for about a month now. Curcumin was proven effective in reducing or eliminating the digestive problems with CF at a cellular level in mice. Not humans. Unfortunately, they are not able to re-create the lung problems in mice so they can't see the effects from that aspect. As far as how it's going with Aiden, I have seen some changes in bowel consistency (ewwww...) meaning more solid, as if CF children EVER have a solid BM... but you know what I mean.
Unfortunately, I found research online the other day that they were unable to re-create the benefits from curcumin in humans during the study. Oh well, it doesn't hurt him.
I will give you a BIG warning here if you're going to give it a shot. Curcumin/Turmeric is VERY yellow. Think AquADEK vibrant, but yellow instead of Orange. It WILL stain clothing. And it does NOT taste very good. To children anyways. It has a VERY strong, pungeant flavor that is really be an eye-popper to children. Now, I give it to him by cutting the tip off the capsule and squeezing it into applesauce and then trying to get it all down in one bite. But, he's way too young to be swallowing capsules (only 17 months) so I have no choice. Once they are old enough to swallow caps, there shouldn't be any issue with overwhelming flavor.

Good luck!
