I have not started any natural supplements. As far as diet is concerned I stay away from a lot of foods and just small amounts of diary... I have not tried going gluten free yet Try to eat gluten free for a couple of weeks to see if your symptoms lessen. Gluten and dairy are the usual suspects but any food can cause problems. So I prefer a food diary or journal to isolate dietary triggers. For example, I always tried to eat healthy for years with generous amounts of cruciferous vegetables, etc. Now I find that cruciferous such as kale and broccoli trigger flare symptoms.
As far as other alternatives go, you can almost say that rectal meds such as mesalamine enemas are alternative since so few doctors prescribe them unless specifically requested. But they have an excellent reputation for effectiveness with relatively few side effects.
Popular supplements are fish oil and getting your blood levels of
vitamin D, iron, and B12 checked to correct any deficiencies. Some like me use soluble fiber such as psyllium (Metamucil or psyllium seed). Others swear by herbal demulcents like slippery elm. You can search the forum for these topics.
Probiotics are probably the most popular supplement for IBDers. There are numerous research studies showing that certain probiotics, such as Saccharomyces Boulardii and Culturelle, are effective for maintaining remission. VSL#3 is shown to prevent pouchitis. Benebiotic and RenewLife Ultimate Flora are also very popular choices. But we are all different and certain probiotics are more compatible than others.
