TL;DR

Reducing inflammation and balancing gut bacteria can make a big difference for people with Crohn’s disease and ulcerative colitis (collectively called inflammatory bowel disease, or IBD). These strategies are not treatments, but they are well-researched ways to support gut health:

  1. Specific Carbohydrate Diet (SCD): 45–66% of IBD patients may achieve remission [1,2,3,4,5,6].

  2. Berberine: Helps restore microbiome balance and reduce inflammation [8,9,10,11,12,13,14]. A good quality product is available from Life Extension. One, 3x/day is an appropriate dose.

  3. Curcumin: Supports gut healing and reduces inflammation, though it needs help with absorption [15,16]. Curcumin is poorly absorbed. A combination formula, like Advanced Curcumin Elite™ Turmeric Extract, Ginger & Turmerones, from Life Life Extension has components that aid absorption. One, 3x/day is an appropriate dose.

The Specific Carbohydrate Diet (SCD) and IBD

Elaine Gottschall, in her book Ending the Vicious Cycle, showed how avoiding complex carbohydrates can help nearly half of patients with Crohn’s disease or ulcerative colitis.

Her reasoning:
Incomplete digestion → Growth of improper GI flora → Irritation of the intestinal lining → Decreased enzyme production → More improper flora → Inflammation → IBD.

Foods to Avoid on SCD:

  • Sugar, molasses, sucrose, processed fructose

  • All grains (wheat, corn, rice, barley, oats)

  • Canned vegetables with additives

  • Most legumes

  • Starchy tubers (potatoes, yams, turnips)

  • Processed meats and oils

  • Dairy high in lactose

  • Candy and chocolate (anything with refined sugar)

Note: While SCD allows some cheese and dry curd cottage cheese, many people do best by avoiding all dairy and starches.

Modern refinements These can be found on The Roadmap to Health (edited for IBD sufferers):

  • Emphasize whole, organic produce (up to 75% of diet by volume). Caveat: Some IBD sufferers have trouble tolerating a lot of fiber. If this is you, eat as much produce as you can without triggering symptoms (it may be less than we are recommending).

  • Avoid food additives, GMOs, and processed oils.

  • Use olive, coconut, or avocado oil instead of processed oils.

Berberine and the Gut Microbiome

Berberine, a plant-derived alkaloid, has been shown to:

  • Balance intestinal bacteria

  • Suppress pro-inflammatory pathways

  • Support mucosal healing

Suggested dose: 500 mg, 3x/day (Life Extension and other professional brands carry quality products).

Evidence shows berberine may significantly reduce inflammation in ulcerative colitis and Crohn’s models [8,9,10,11,12,13,14].

Curcumin for Gut Inflammation

Curcumin, the active compound in turmeric, is well-studied for its anti-inflammatory effects in IBD [15,16].

Challenge: Curcumin is poorly absorbed on its own.

Solutions:

Suggested dose: 1 softgel, 3x/day.

Beyond Diet and Supplements

If diet and basic supplementation do not bring results, additional strategies may help — preferably under the guidance of a functional medicine practitioner:

  • Natural antimicrobials: oregano oil, olive leaf, garlic, caprylic acid

  • Mucosal healing: glutamine, colostrum, bone broth, butyrate, aloe

  • Stool testing: GI-MAP and similar tests can identify bacteria, inflammation, and mucosal damage

Note: These require professional interpretation. Don’t try to self-manage advanced IBD.

Key Takeaways

  • Roughly half of IBD patients may benefit from SCD.

  • Berberine and curcumin have strong research support for gut healing and inflammation control.

Crohn’s & Ulcerative Colitis FAQ

Q1. What percentage of Crohn’s patients go into remission on the Specific Carbohydrate Diet (SCD)?
Studies show that between 45% and 66% of patients with Crohn’s or ulcerative colitis report remission when following the SCD [1–6]. Results vary by adherence level, patient age, and whether the diet is paired with other therapies.

Q2. Is the Specific Carbohydrate Diet safe for children with Crohn’s disease?
Yes, pediatric studies show the SCD can be nutritionally adequate when properly managed [3]. However, children may need extra monitoring to ensure sufficient calories, vitamins, and minerals. Work with a doctor or dietitian familiar with IBD.

Q3. How much berberine should someone with IBD take?
Clinical reviews suggest 500 mg three times per day (total 1,500 mg daily) can improve microbiome balance and reduce gut inflammation [8–14].

Q4. Is berberine safe for long-term use in Crohn’s or ulcerative colitis?
Most studies are short-term (8–12 weeks). Animal and early human studies suggest it is generally safe, but long-term effects need more data. Because berberine also lowers blood sugar, patients with diabetes or hypoglycemia should use caution.

Q5. Does curcumin actually help with Crohn’s or ulcerative colitis symptoms?
Yes. A recent meta-analysis found that curcumin significantly improved remission rates and reduced inflammation compared to placebo in IBD patients [15,16]. It is most effective when taken with absorption enhancers (like piperine, ginger, or specialized formulations).

Q6. How can I improve absorption of curcumin if my supplement doesn’t contain piperine?
Options include:

  • Taking curcumin with a fat-rich meal (since it’s fat-soluble).

  • Choosing a formula with added ginger or turmerones, which improve bioavailability.

  • Using emulsified or nanoparticle curcumin products, which are shown to increase absorption.

Q7. Can I follow the SCD and still eat dairy products?
The original SCD allows certain hard cheeses and dry curd cottage cheese. However, many people with IBD still react poorly to dairy. A stricter version — avoiding all dairy — may yield better results. Some patients do better on a modified Paleo diet that overlaps with SCD.

Q8. Should I try supplements first or stool testing first?
If you’re trying to manage IBD on your own, the safest first steps are diet and low-risk supplements like berberine and curcumin. Stool testing (such as GI-MAP) provides more detailed insights into microbiome imbalances and mucosal health, but requires a functional medicine practitioner to interpret.

Q9. Are probiotics or Saccharomyces boulardii useful in Crohn’s or ulcerative colitis?
Yes. Several trials suggest S. boulardii may help maintain remission in Crohn’s and ulcerative colitis, particularly after antibiotic use. It can reduce diarrhea and improve microbiome balance. Not all probiotics are equal — strain-specific results matter.

Q10. What if I follow the diet and supplements but still don’t improve?
This does not mean your case is hopeless. It may mean:

  • Hidden food sensitivities are still driving inflammation.

  • The microbiome imbalance requires more targeted antimicrobials.

  • You need mucosal healing support (e.g., glutamine, colostrum, butyrate).

  • Thyroid or adrenal support may be necessary.
    At this point, work with a functional medicine doctor for a personalized plan.
