Hi Diane,
Welcome to the forum.
Sorry you're in a bad flare currently, hopefully you'll be able to get it under control soon.
I take: vitamin d3, vitamin k2, probiotics, slippery elm powder, l-glutamine, maca powder, l-threonine amino acid powder, chia seeds, and liquid minerals and liquid vitamins (which I add to my protein shakes). I have tried Boswellia but haven't had any success with it. Have not tried ginger or turmeric. Zinc is included in my liquid minerals. But I do take magnesium by rubbing a special magnesium oil on my belly every night.
I would suggest you look into adding probiotics, VSL #3 are the best ones IMO, and if you can get your doc to prescribe it to you as VSL#3DS that would be great, slippery elm powder, and L-glutamine to handle the liquid D, and also for long term colonic repair.
What about diet modification?
Also, there's LDN, low dose naltrexone.
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.
Are you on any rectal meds? Those would be very helpful as well.
I hope you feel better and let us know how we can help you.
