Has anyone tried this?

It was mentioned as a treatment on the Center for Digestive disease website in Sydney http://www.ncbi.nlm.nih.gov/m/pubmed/11121904/

Haven't tried it, but this reminds me of the poster on here some time ago who always improved when eating steamed lobster. She speculated that it might have been due to the N-acetyl glucosamine in the shells.

I wish there was funding for some large placebo controlled studies of supplements for IBD. These tiny studies of 10-20 people always seem interesting, but far too small to be meaningful.

Yes, I tried it and it helped I think. A naturopath friend told me about it about 25 years ago, it was quite cheap back then. Trouble is I can only find really expensive supplements now so I haven't used it. I last had it in a supplement from Biocare called Permatrol which was quite a good mix.

I only take supplements for a very short time now if I do use them having had adverse effects from various supplements if I over do them.
