How is your ulcerative colitis showing up for you right now?

I'm in a flare — cramping, urgency, or loose stools right now

Curcumin
Supported by controlled trials· Centuries of traditional use (Evidence grade A · Traditional use long-standing)Long-standing traditional staple
Clinically studied for mild-moderate UC flares
Why this matches
If you're in a flare, curcumin's anti-inflammatory action is where the clinical research is strongest — a meta-analysis of randomized trials found it improved remission in mild-to-moderate UC when added to standard treatment.
Why try it
Curcumin is thought to help calm intestinal inflammation by modulating key inflammatory pathways in the gut lining; in trials it was used alongside, not instead of, prescribed UC treatment.
Dose or use
Follow product labeling; consult a healthcare practitioner. (Nano or phospholipid forms may improve absorption.)
Time to results
Typically 4–8 weeks
Key study
Systematic review and meta-analysis (2025, PMID 39612780): Safety and efficacy of curcumin in the treatment of ulcerative colitis — pooled 8 RCTs (482 patients) found adjunctive curcumin roughly doubled clinical remission versus placebo in mild-to-moderate UC.
Caution
May interact with blood thinners; use caution before surgery or if pregnant.
Sodium Butyrate
Supported by smaller clinical studies· Recognised traditional use (Evidence grade B · Traditional use recognised)Recognised traditional use
Colon-targeted fuel trialed for calming active UC
Why this matches
If you're in a flare, microencapsulated (colon-release) sodium butyrate is one of the more directly studied natural add-ons — a randomized, placebo-controlled trial in people with active mild-to-moderate UC tested it alongside standard therapy.
Why try it
Butyrate is the main fuel for the cells lining your colon; a colon-release form is thought to support the gut barrier and dampen inflammation, and in trials it was used on top of prescribed treatment rather than in place of it.
Dose or use
Commonly studied at about 600 mg/day of a colon-targeted (microencapsulated) form; follow product labeling and use alongside your prescribed UC treatment.
Time to results
Typically around 8 weeks in studies
Key study
Randomized controlled trial (2025, PMID 41422374): Efficacy of Microencapsulated Sodium Butyrate as Add-On Therapy in Inducing Remission in Patients with Mild-To-Moderate Ulcerative Colitis — 98 adults with active UC received colon-targeted butyrate (2×300 mg/day) or placebo for 8 weeks added to standard care, with significantly more clinical improvement in the butyrate group.
Caution
Generally well tolerated; may cause mild gas or bloating. It's an add-on, not a replacement for your prescribed UC medication — check with your clinician, especially if pregnant.
Bromelain
Supported by smaller clinical studies· Recognised traditional use (Evidence grade B · Traditional use recognised)Recognised traditional use
Pineapple enzyme trialed for UC disease activity
Why this matches
During a flare, bromelain — a protein-digesting enzyme from pineapple — has been tested in a randomized, placebo-controlled trial in people with mild-to-moderate UC for its effect on disease activity and quality of life.
Why try it
Bromelain is thought to have anti-inflammatory effects in the gut; in the trial it was added to usual care rather than used on its own.
Dose or use
Studied at 400 mg daily for 8 weeks; follow product labeling (enteric-coated forms survive stomach acid) and use alongside your prescribed treatment.
Time to results
Typically around 8 weeks in the trial
Key study
Randomized controlled trial (2025, PMID 41315628): Effects of bromelain supplementation on disease activity and quality of life in patients with ulcerative colitis — 70 people with mild-to-moderate UC took 400 mg bromelain daily or placebo for 8 weeks, with disease activity (SCCAI) and quality of life assessed.
Caution
May thin the blood and can interact with blood thinners and antibiotics; avoid if allergic to pineapple, use caution before surgery, and check with your clinician if pregnant. It's an add-on, not a replacement for prescribed UC care.
Boswellia
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Anti-inflammatory resin used for gut inflammation
Why this matches
During a flare, boswellia is a botanical that has traditionally been used to calm inflammation in the gut lining, making it a gentle companion to curcumin for cramping and urgency.
Why try it
Boswellic acids in the resin are thought to dampen inflammatory pathways in the colon, which is why boswellia has long been used for inflammatory bowel complaints.
Dose or use
Follow product labeling; consult a healthcare practitioner. Standardized extracts are usually taken with food.
Time to results
Typically 4–8 weeks
Key study
Traditionally used to ease inflammatory bowel symptoms; this specific use in ulcerative colitis has not been confirmed here in controlled clinical trials.
Caution
May cause mild digestive upset or heartburn, and can interact with medications processed by the liver; check with your clinician if pregnant.
Slippery Elm (Ulmus rubra)
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Soothing demulcent for an irritated gut lining
Why this matches
When you're flaring with cramping and loose stools, slippery elm's mucilage forms a slick, protective coating that has traditionally been used to soothe an irritated gut lining.
Why try it
The inner bark is rich in mucilage, a gel-like fiber that swells in water and is thought to coat and calm inflamed digestive tissue.
Dose or use
Follow product labeling; commonly taken as a powder stirred into water or as capsules. Take with plenty of fluid.
Time to results
Often felt within days for comfort; ongoing use varies
Key study
Traditionally used to soothe the gut lining; this specific use in ulcerative colitis has not been confirmed here in controlled clinical trials.
Caution
Its coating action can slow absorption of other medications and supplements — take them at least two hours apart.
ST25 (Tianshu) - Stomach 25
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Abdominal point used for cramps and loose stools
Why this matches
This point sits about two finger-widths beside your navel, right over the colon, and is traditionally used for the diarrhea, cramping and bloating that come with a flare.
Why try it
In traditional Chinese medicine ST25 is a key abdominal point for regulating the bowels, and gentle pressure is used to ease digestive discomfort.
Dose or use
Apply gentle, steady pressure with a fingertip for 1–2 minutes on each side, breathing slowly; repeat as needed.
Time to results
Some ease may be felt within minutes; effects are temporary
Key study
A traditional acupressure point used for digestive complaints; this specific use in ulcerative colitis has not been confirmed here in controlled clinical trials.
Caution
Use only light pressure during a severe flare, avoid if pregnant, and stop if it increases pain.

I'm mostly settled and want to protect my remission

Curcumin
Supported by controlled trials· Centuries of traditional use (Evidence grade A · Traditional use long-standing)Long-standing traditional staple
Clinically studied for mild-moderate UC flares
Why this matches

Caution
May interact with blood thinners; use caution before surgery or if pregnant.
Probiotics
Supported by smaller clinical studies· Centuries of traditional use (Evidence grade B · Traditional use long-standing)Long-standing traditional staple
RCT-backed add-on for supporting UC remission
Why this matches
When you're mostly settled, probiotics are among the better-studied natural options for UC — pooled randomized trials suggest that, added to standard therapy, they can help support remission. Which strain and product you choose matters.
Why try it
Beneficial bacteria are thought to help keep the gut environment balanced and support the intestinal lining; trials have added them on top of standard UC treatment rather than replacing it.
Dose or use
Follow product labeling; multi-strain formulations taken daily are common. Introduce slowly.
Time to results
Typically 4–8 weeks of consistent use
Key study
Systematic review and meta-analysis (2024, PMID 38446227): Additive efficacy and safety of probiotics in the treatment of ulcerative colitis — pooled 13 RCTs (930 patients) found probiotics added to standard therapy improved remission rates; results vary by strain and product.
Caution
Some people notice temporary gas or bloating when starting; check with your clinician first if you are immunocompromised.
Vitamin D Deficiency
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Low vitamin D is common with IBD
Why this matches
For ongoing gut support, vitamin D is worth attention — low levels are common in inflammatory bowel disease and play a role in immune regulation that matters for staying settled.
Why try it
Vitamin D helps regulate the immune system and support bone and gut health; correcting a genuine shortfall is a recognized supportive step.
Dose or use
Have your level checked, then follow your clinician's guidance on dose; fat-soluble, so take with a meal.
Time to results
Weeks to a few months to raise blood levels
Key study
Low vitamin D is consistently associated with IBD activity; this is an association, and correcting deficiency should be guided by testing rather than assumed to treat the condition.
Caution
High-dose supplementation should be monitored with bloodwork, as too much vitamin D can raise calcium to unsafe levels.
Berberine
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
Traditionally used for gut and digestive health
Why this matches
If your symptoms are currently settled and you're looking for ongoing gut support, berberine has been traditionally used to promote a balanced gut environment and healthy digestion.
Why try it
Traditionally used to support gut microbial balance and intestinal lining integrity, which may help maintain overall digestive wellness. It is not a substitute for your prescribed UC treatment.
Dose or use
Follow product labeling; consult a healthcare practitioner.
Time to results
Typically 4–8 weeks
Key study
Traditionally used for digestive complaints; this specific use in ulcerative colitis has not been confirmed in controlled clinical trials.
Caution
May interact with medications including antibiotics and blood sugar-lowering drugs; avoid in pregnancy.

I feel drained — unusually tired, breathless, or run-down between symptoms

Iron Deficiency
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Ongoing bleeding can quietly drain iron stores
Why this matches
Flares often come with rectal bleeding, and steady blood loss is the most common way UC drains iron — worth checking if you feel unusually tired, breathless, or pale.
Why try it
Low iron leads to anemia, which can leave you fatigued and short of breath; identifying and correcting a genuine deficiency can restore energy.
Dose or use
Confirm with bloodwork (ferritin and hemoglobin) before supplementing, then follow your clinician's guidance on dose and form.
Time to results
Weeks to a few months to rebuild stores
Key study
Iron-deficiency anemia is a recognized consequence of the chronic blood loss seen in ulcerative colitis; individual causes should be confirmed with testing.
Caution
Don't self-supplement without testing — excess iron can cause constipation and stomach upset and may worsen GI symptoms.
Vitamin D Deficiency
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Low vitamin D is common with IBD
Why this matches
For ongoing gut support, vitamin D is worth attention — low levels are common in inflammatory bowel disease and play a role in immune regulation that matters for staying settled.
