seasons21,
Yes, I concur: don't worry so much about legal vs. illegal SCD supplements.
I've found Slippery Elm Powder to be great - and IMO it is nature's mesalamine because it coats the whole digestive tract.
Are you doing any probiotics?
I've found VSL#3 to be great. Did you know it is especially formulated for UC, with 450 billion active cultures?
And if you have decent insurance, you could get your doc to prescribe VSL#3 DS (double strength) to take and it might only cost you a small copay.
As far as LDN, it has worked for me, and for many others on the forum. And I'm sure it will help you too.
What do you think?
