Top 5 Anti-Inflammatory Supplements for Crohn's and Colitis
May 19, 2025

In this article, we'll explore the five most promising anti-inflammatory supplements for IBD, based on current scientific evidence. We'll also discuss how technology can help you integrate these supplements into your overall IBD management plan.
The Inflammation Connection in IBD

Inflammation causes the microvilli to become inflammed, shorten, and produce less enzymes to break down food. This leads to intestinal permeability which can lead to immune responses.
Before diving into specific supplements, it's important to understand why targeting inflammation matters. In IBD, the immune system mistakenly attacks the digestive tract, triggering chronic inflammation that damages the intestinal lining. This inflammation is responsible for the hallmark symptoms of IBD: abdominal pain, diarrhea, fatigue, and weight loss.
While medications work to suppress this inflammatory response, certain dietary supplements may offer additional support by:
- Directly inhibiting inflammatory pathways
- Supporting the gut microbiome
- Strengthening the intestinal barrier
- Reducing oxidative stress
Let's explore the top five supplements that show the most promise for IBD patients.
1. Curcumin (from Turmeric)

Forms of Curcumin include raw root, powder spice, and capsule supplements.
What it is: Curcumin is the active compound in turmeric, a bright yellow spice used in many cuisines, particularly Indian food.
How it helps: Curcumin has powerful anti-inflammatory and antioxidant properties. Research shows it can help reduce inflammation in ulcerative colitis specifically by:
- Inhibiting inflammatory pathways like NF-κB
- Reducing the production of inflammatory cytokines
- Protecting the intestinal barrier
The evidence: Multiple clinical trials have shown that curcumin, when used alongside conventional medications like mesalamine, can help induce and maintain remission in patients with mild to moderate ulcerative colitis. A meta-analysis found that curcumin significantly improved clinical remission rates compared to placebo.
Typical dosage: 1-3 grams daily, often divided into multiple doses.
Important considerations: Curcumin has poor bioavailability, meaning your body doesn't absorb it well. Look for supplements that include black pepper extract (piperine) or are formulated for enhanced absorption. The evidence is stronger for ulcerative colitis than for Crohn's disease.
2. Omega-3 Fatty Acids (Fish Oil)

Sources of Omega-3 Fatty Acids include fish, nuts, seeds, capsule supplements.
What they are: Omega-3 fatty acids, particularly EPA and DHA, are essential fats found primarily in fatty fish like salmon, mackerel, and sardines.
How they help: Omega-3s have natural anti-inflammatory properties that may benefit IBD patients by:
- Producing anti-inflammatory compounds called resolvins and protectins
- Reducing pro-inflammatory cytokines
- Improving the gut microbiome composition
The evidence: Research on omega-3s for IBD shows mixed but promising results. Some studies indicate they may help reduce inflammation and improve symptoms in both Crohn's disease and ulcerative colitis. DHA specifically may have protective effects against Crohn's disease development.
Typical dosage: 1-2 grams of combined EPA and DHA daily.
Important considerations: Quality matters with fish oil supplements. Look for products that have been tested for purity and are free from contaminants like mercury. Take with meals containing fat for better absorption.
Here are the Fish Oil products that I use:
- Carlson - Cod Liver Oil, 1100 mg Unflavored, 250 mL (8.4 Fl Oz)
- Carlson - Maximum Omega 2000 (Lemon flavor), 90 soft gels
These are SCD, GAPS, Paleo AIP, and Mediterranean allowed.
3. Vitamin D

Sources of Vitamin D pictured include supplements, milk, salmon, and eggs.
What it is: Vitamin D is a fat-soluble vitamin that functions more like a hormone in the body. While we can produce it through sun exposure, many people with IBD are deficient.
How it helps: Vitamin D plays a crucial role in immune function and inflammation regulation by:
- Modulating immune responses
- Reducing inflammatory cytokines
- Potentially improving gut barrier function
- Supporting beneficial gut bacteria
The evidence: There's a well-established link between vitamin D deficiency and IBD. Studies show that maintaining adequate vitamin D levels correlates with less active disease, fewer flares, and better outcomes with biologic therapies. Low vitamin D levels are associated with increased disease severity and relapse risk.
Typical dosage: Highly individualized based on current levels. Your doctor should test your vitamin D levels and recommend an appropriate dosage.
Important considerations: Vitamin D supplementation is often recommended for all IBD patients due to the high prevalence of deficiency and its role in bone health, which can be compromised in IBD.
Here's the Vitamin D that I use:
It is SCD, GAPS, Paleo AIP allowed.
4. Probiotics

Probiotics pictured include yogurt, capsule supplements, milk kefir, kombucha, and sauerkraut.
What they are: Probiotics are beneficial live bacteria that can provide health benefits when consumed in adequate amounts.
How they help: Probiotics may benefit IBD patients by:
- Restoring balance to the gut microbiome
- Strengthening the intestinal barrier
- Modulating immune responses
- Reducing inflammation
The evidence: The effectiveness of probiotics in IBD depends on the specific strain and the type of IBD. Certain strains, like E. coli Nissle 1917 and the multi-strain formulation VSL#3, have shown promise for inducing and maintaining remission in ulcerative colitis. The evidence for Crohn's disease is less compelling.
Typical dosage: Varies by product and strain. Follow package directions or your healthcare provider's recommendations.
Important considerations: Not all probiotics are created equal. Strain specificity matters greatly in IBD. Consult with your healthcare provider about which strains might be most beneficial for your specific condition.
Here's the yogurt starter that I use:
It is SCD and GAPS allowed if you use this as a starter and follow the diet guidelines for making homemade yogurt.
5. Ginger

Forms of Ginger include raw root, powder spice, and capsule supplements.
What it is: Ginger is a flowering plant whose rhizome (root) is widely used as a spice and traditional remedy.
How it helps: Ginger contains bioactive compounds with anti-inflammatory and antioxidant properties that may help IBD patients by:
- Inhibiting inflammatory pathways like COX-2 and NF-κB
- Reducing pro-inflammatory cytokines
- Potentially improving gut microbiota diversity
The evidence: While human clinical trials are limited, preclinical studies show promising results. Ginger and its compounds have been shown to reduce inflammation in animal models of colitis. Recent research identified a compound in ginger (furanodienone) that selectively binds to a nuclear receptor involved in IBD, reducing inflammation.
Typical dosage: Up to 2 grams daily.
Important considerations: Ginger is generally well-tolerated but may have blood-thinning effects at higher doses. Human studies on ginger for IBD are still emerging, so consider it a complementary approach rather than a primary treatment.
Bonus: Glutamine

Glutamine is available as powder, capsules, and naturally in protein-rich foods.
What it is: Glutamine is the most abundant amino acid in the body and plays a crucial role in intestinal health. It serves as a primary fuel source for the cells lining the intestinal tract.
How it helps: Glutamine may benefit IBD patients by:
- Supporting intestinal barrier function and repair
- Reducing intestinal permeability ("leaky gut")
- Decreasing pro-inflammatory cytokine production
- Promoting healing of the intestinal lining
The evidence: Research on glutamine for IBD shows some promising results, particularly for intestinal permeability issues. Studies indicate that glutamine supplementation may help maintain remission in some IBD patients by strengthening the intestinal barrier. However, clinical trials specifically for Crohn's disease and ulcerative colitis have shown mixed results, with some studies showing benefits while others show limited effects.
Typical dosage: 5-10 grams daily, often divided into multiple doses.
Important considerations: Glutamine is generally well-tolerated, but should be used with caution in patients with liver or kidney disease. It's best taken on an empty stomach or between meals for optimal absorption. While glutamine plays a crucial role in intestinal health, more large-scale clinical trials are needed to fully establish its efficacy specifically for IBD management.
Author Note: I have taken Glutamine off and on for many years to help with my Crohn's disease strictures. It's an essential supplement for me to enjoy a wider diet. I think of it as making the scar tissue more flexible and food is less likely to get blocked in my intestines.
Here are some options for purchasing Glutamine:
- THORNE L-Glutamine Powder - 17.8 Oz - Excellent quality
- Doctors Best Pure L-Glutamine Powder - 10.6 Oz - High quality, value price
- BulkSupplements.com L-Glutamine Powder - 500g (1.1 lbs) - Bulk amount
It's one of those supplements that appears to be easy enough to make that nearly any brand I've tried has been good quality. Don't over think who you buy from as long as the price is right for you. It is SCD, GAPS, Paleo AIP, and Mediterranean allowed.
