I think I've only heard of such a product for animals. (Eww, like cud?)
I would think it would have to involve some enzymes or something, not just blended. And your colon doesn't really do the digestion part of processing food, so I'm not sure it would help UC. But I see you are having trouble with your stomach, maybe not your UC...
Maybe you should cut down the supplements, things that aren't actually prescribed? Vitamin formulas and other supplements can cause stomach upset.
