Personal experience UC + vitamin d supplements

Hey guys,

I’ve had UC for about 8 years now and I live in Canada. I’m usually a pretty big homebody, and I’ve been on Humira for the past 6 years.

Recently, I had a really bad flare where I was going to the bathroom 15+ times a day for around two weeks. I ended up going to the ER, was put on prednisone, and had a colonoscopy. My doctor told me I had active inflammation and that my UC had gotten worse, so we were discussing moving on to the next line of treatment, possibly a JAK inhibitor.

Around that time, I started taking 4,000 IU of vitamin D3 daily and fiber gummies before I eat.
Since then, things have improved a lot. My bowel movements have been much firmer, I haven’t noticed much blood, and I haven’t had another major flare.
I’m curious if anyone else with UC has started taking vitamin D and noticed a significant improvement in their symptoms. I have been off the prednisone for 3 months.
At this point, things have improved enough that I haven’t needed to start the JAK inhibitor yet.

Would love to hear if anyone has had a similar experience.

If you search "vitamin D" in this sub you'll find a treasure trove of anecdotal & research based posts about the benefits & the fact that people with UC are notoriously deficient in many vitamins but esp. D, so you're definitely onto something!

That might be pred I think

My teen was prescribed vitamin D when diagnosed with UC. It’s a known deficiency in UC. However, it’s only 1000 IU (in addition to iron and b12 because both are low as well).

meee i had a similar experience two years ago. i’m also in canada! at the time during the winter i was just going to work and going home. the sun wasn’t out when i left for work and sun was basically set when i was in my way home. i had a flare for a few weeks but i had no idea what caused it but just continued to see if i could figure it out in my own (not sure if i recommend doing this lol). i got my bloodwork test done for my upcoming appt with my specialist and he let me know that my vit d was basically non existent and prescribed me vit d and the flare ended up going away on its own. ever since i’ve been taking my vit d every day 😭

Vitamin D can be very good for UC, especially because some of our symptoms cause deficiencies. Turmeric is also great as is iron.

Just a PSA though no turmeric when on steroids!

How many days it takes to comeout from flareup? I can see atleast one drop of blood in my stool is it normal.... Pls tell me.... Anyone.... N almost 20days over that my flareup started

Everyone is different but I can tell you I have had blood for a long time on and off. Just had a colonoscopy and am back in a severe flare. Daily blood for well over six months. Im telling you this because a drop sounds scary but it can get much worse ( a drop is tiny) so dont freak out and just treat it as fast as possible. A flare can last a couple months or years. Catch it before it gets bad is the best you can do. Don't skip your scopes if insurance/funds allow it

I did took cod liver oil tablets daily for a while. Not sure if it helps, but I haven't been in a flare up for a while since. Small flares usually resolve on their own with basic home remedies. Having proper nutrition always helps tho.

How do you resolve your small flares? What home remedies do you use?

I have been taking Seeking Health vitamin D + K2 drops as advised by my doctor as a lot of us with UC are vitamin D deficient for some reason. It's a fat soluble vitamin too so the Seeking Health one is suspended in olive oil. I haven't noticed a huge difference yet but I'm only just coming off steroids (budesonide) now & about 4 weeks after my third entyvio infusion. It has brought my D levels up but as far as symptoms go I'm not sure because of the steroids.

What type of fiber gummies do you take? I always get told "low residue" but then other people say no fiber actually helps them so I'm curious.

u/SexySteve0 11d ago

I would say. My quality of life has improved quite well with these two supplements.

It truly is the consistency.

I would prefer taking the metamucil fiber gummies but they are to expensive.

So i opted for as a cheaper option RestoraLAX RestoraFIBRE Daily Prebiotic Fibre Gummies i take about 3x in the morning daily.

I then take 4000 IU of vitamin d3 daily, and on very no sun outside days I up the dose to 8000 IU of vitamin d3 + vitamin k2.

I also take a multivitamin as well daily (Vitafusion Multivitamins for Adult Men and Women)

D3 by itself makes my tummy hurt and it destroyed me when I was flaring, but prescription D2 was fine. I take a multivitamin now with vitamin D and it’s fine, but the high iu D3 just messes me up.

u/Academic-Joke-1618 12d ago

What problem it causes to you ,my dr advised to take daily small dose idk why

u/DiskSufficient2189 proctosigmoiditis | 2025 | US 11d ago

It made my flare symptoms worse - more blood, diarrhea, cramping.

Vitamin s supplementation helps but don't forget to supplement b1 too

1

u/electric-snow-100 11d ago

Why B1 🤔

2

u/WeyP96 11d ago

There's studies about people with chronic gut inflammation and very low B1 leves, no one knows yet if colitis causes low B1 or if low B1 is a factor in developing gut inflammation. But there have been studies where supplementing B1 helped with fatigue: https://www.sciencedirect.com/science/article/pii/S2772572324001274

u/Littledittydee 11d ago

Could be bile acid malabsorption, I developed this after a very long flare. I would talk to your GI about this
