Aegan,
Welcome to the forum.
Sorry about you're feeling lousy.
I see you're being proactive by taking: krill oil, l-glutamine, diet, etc...
which is very good.
I would also suggest you look into adding slippery elm powder which coats the whole tract.
How much l-glutamine are you using? Capsules? Powder form?
WHich diet?
How about looking into LDN, low dose naltrexone too?
If you are interested, there are things IMO that you can control, which will have a direct impact on your disease, the symptoms you experience and their severity.
I was able to control my UC into remission through various supplements, probiotics, diet modification, and LDN , low dose naltrexone.
For more info on the protocol which has put me into
remission, please go to this link: https://www.healingwell.com/community/default.aspx?f=38&m=1666318 , and look at the 11th post.
I hope you feel better and let us know how we can help you.
