If you’re researching SIBO natural treatment options, you’re likely frustrated by recurring symptoms, limited guidance from conventional medicine, or concerns about antibiotic side effects. As a board-certified physician who transitioned from oncology to functional medicine, I’ve treated hundreds of SIBO cases using evidence-based natural protocols that address root causes rather than simply suppressing symptoms.
Small Intestinal Bacterial Overgrowth (SIBO) affects an estimated 6-15% of the general population and up to 78% of those with Irritable Bowel Syndrome (IBS). While conventional medicine typically relies on repeated antibiotic courses, research demonstrates that herbal antimicrobial protocols achieve comparable success rates with significantly fewer side effects and lower recurrence rates.
Living and practicing in South Florida, I’ve observed how our region’s unique environmental factors—including high humidity averaging 75% year-round and prevalent mold exposure—can complicate SIBO treatment and contribute to gut dysfunction. This comprehensive guide provides the evidence-based SIBO natural treatment options I use in my practice, personalized for the challenges facing patients in our subtropical climate.
Understanding SIBO: Beyond Basic Definitions
What Makes SIBO Different from Other Gut Issues?
SIBO occurs when bacteria that normally reside in the large intestine migrate upward and overpopulate the small intestine, where they ferment carbohydrates and produce excessive gas. Unlike normal digestion, this bacterial overgrowth creates:
Hydrogen-Dominant SIBO (Most Common – 65% of cases)
- Caused by bacteria producing hydrogen gas
- Symptoms: Diarrhea-predominant, urgent bowel movements
- Breath test shows elevated hydrogen levels (>20ppm increase)
Methane-Dominant SIBO (IMO – Intestinal Methanogen Overgrowth)
- Caused by archaea (methanogenic organisms) producing methane
- Symptoms: Constipation-predominant, bloating, weight gain
- Breath test shows elevated methane levels (>10ppm)
Hydrogen Sulfide SIBO (Emerging Recognition)
- Caused by sulfate-reducing bacteria
- Symptoms: Sulfur-smelling gas, diarrhea, burning sensation
- Often shows flat breath test results (gas absorbed before measurement)
Why SIBO Keeps Coming Back: The Root Cause Problem
Research reveals that 44% of SIBO patients experience recurrence within 9 months after antibiotic treatment alone. This high recurrence rate reflects a fundamental limitation of conventional approaches: treating bacterial overgrowth without addressing the underlying factors that allowed SIBO to develop.
Common Root Causes of SIBO:
| Root Cause | Mechanism | Prevalence | Treatment Priority |
|---|---|---|---|
| Low stomach acid | Reduced bacterial killing in upper GI | 50-70% of cases | Restore HCl production |
| Impaired motility | Reduced migrating motor complex (MMC) | 60-80% of cases | Prokinetic support |
| Structural abnormalities | Adhesions, strictures, fistulas | 15-25% of cases | May require surgical evaluation |
| Immune dysfunction | Low secretory IgA | 30-40% of cases | Immune system support |
| Ileocecal valve dysfunction | Bacterial backflow from colon | 20-30% of cases | Manual therapy, supplements |
The key to successful SIBO natural treatment options lies in simultaneously addressing bacterial overgrowth while correcting these underlying dysfunction patterns.
Evidence-Based Herbal Antimicrobial Protocols
The Research Behind Natural SIBO Treatment
A landmark 2014 study published in Global Advances in Health and Medicine demonstrated that herbal antimicrobial therapy achieved 46% SIBO eradication, compared to 34% with the pharmaceutical antibiotic Rifaximin. More importantly, when herbal protocols were combined with appropriate dietary modifications and prokinetic support, success rates increased to 85%.
Subsequent research has confirmed these findings, with herbal antimicrobials showing:
✅ Comparable or superior efficacy to pharmaceutical antibiotics
✅ Significantly fewer side effects (minimal disruption to beneficial gut bacteria)
✅ Lower recurrence rates when combined with root cause treatment
✅ Better patient tolerance and treatment compliance
✅ Cost-effectiveness compared to repeated antibiotic courses
Hydrogen-Dominant SIBO Herbal Protocol
Phase 1: Initial Antimicrobial Treatment (4-6 weeks)
Primary Herbal Antimicrobials:
- Berberine Complex (500mg, 3x daily before meals)
- Broad-spectrum antimicrobial activity
- Supports healthy glucose metabolism
- Enhances gut barrier function
- Research shows 70% reduction in hydrogen-producing bacteria
- Oregano Oil (Emulsified, 150mg, 3x daily with meals)
- Powerful against gram-positive and gram-negative bacteria
- Anti-biofilm properties
- Natural prokinetic effects
- Requires emulsified form for small intestine delivery
- Neem Extract (300mg, 2x daily)
- Targets resistant bacterial strains

- Goldenseal: 400mg, 2x daily – berberine source, mucous membrane support
Treatment Timeline:
- Weeks 1-2: Begin with single antimicrobial (usually berberine)
- Weeks 3-4: Add second antimicrobial (oregano or neem)
- Weeks 5-6: Full protocol with rotation of supporting herbs
- Week 7: Rest week – no antimicrobials
- Week 8: Retest breath test
Methane-Dominant SIBO (IMO) Herbal Protocol
Methane-producing organisms (archaea) are notoriously more difficult to eradicate than hydrogen-producing bacteria. Research shows that methane SIBO requires longer treatment duration (typically 8-12 weeks) and specific antimicrobial combinations.
Enhanced Methane-Targeted Protocol:
- Allicin (High-dose: 900mg, 3x daily)
- Primary anti-archaeal agent
- Must be stabilized allicin (not aged garlic)
- Take on empty stomach for optimal absorption
- Oregano Oil (Emulsified, 200mg, 3x daily)
- Synergistic with allicin
- Disrupts archaeal cell walls
- Reduces biofilm formation
- Neem + Berberine Combination (300mg neem + 500mg berberine, 2x daily)
- Targets mixed overgrowth (often present with methane)
- Enhances motility
- Reduces methane production
Additional Methane-Specific Support:
- Partially Hydrolyzed Guar Gum (PHGG): 5g daily – selective prebiotic that doesn’t feed methane producers
- Magnesium Citrate: 300-500mg at bedtime – supports motility, relieves constipation
- Ginger Root Extract: 250mg, 2x daily – natural prokinetic
Extended Treatment Timeline:
- Weeks 1-4: Build up to full antimicrobial protocol
- Weeks 5-8: Continue full protocol
- Weeks 9-10: Rest period with prokinetic support only
- Week 11: Retest breath test
- Week 12+: Continue if methane still elevated (>10ppm)
Hydrogen Sulfide SIBO Protocol
Hydrogen sulfide SIBO represents the most challenging subtype, often presenting with severe symptoms despite negative or flat breath tests. Treatment requires a modified approach focusing on sulfate-reducing bacteria and supporting sulfur detoxification pathways.
H2S-Targeted Herbal Protocol:
- Bismuth Subnitrate (262mg, 4x daily with meals)
- Binds hydrogen sulfide gas
- Reduces sulfur-related symptoms
- Provides anti-biofilm activity
- Berberine + Oregano Combination (500mg + 150mg, 3x daily)
- Targets sulfate-reducing bacteria
- Broader antimicrobial coverage
- Supports motility
- Molybdenum (150mcg, 2x daily)
- Essential cofactor for sulfite oxidase enzyme
- Supports sulfur metabolism
- Reduces sulfur sensitivity
Dietary Modifications for H2S SIBO:
- Temporary reduction (not elimination) of high-sulfur foods
- Avoid: eggs, cruciferous vegetables, garlic, onions (during acute phase)
- Emphasize: low-sulfur proteins, well-cooked vegetables, white rice
- Duration: 4-6 weeks, then gradual reintroduction
The Complete SIBO Treatment Framework
Phase 1: Preparation (1-2 Weeks)
Objective: Optimize digestive function before antimicrobial treatment
Key Interventions:
- Digestive Support
- Betaine HCl with Pepsin: Start with 1 capsule (650mg) per protein meal
- Digestive Enzymes: Comprehensive formula with lipase, protease, amylase
- Rationale: Supports proper breakdown of food, reduces bacterial fermentation substrate
- Gut Barrier Support
- GlutaShield: 1 scoop daily
- Contains L-glutamine (4g), DGL (400mg), Aloe Vera (75mg), Zinc Carnosine
- Supports intestinal lining integrity during antimicrobial treatment
- Dietary Transition
- Begin low-FODMAP or Specific Carbohydrate Diet (SCD)
- Reduce fermentable substrate for bacteria
- Minimize symptom flare during treatment
Phase 2: Antimicrobial Treatment (4-12 Weeks)
Duration depends on SIBO subtype:
- Hydrogen SIBO: 4-6 weeks
- Methane IMO: 8-12 weeks
- Hydrogen Sulfide: 6-10 weeks
- Mixed presentation: 8-12 weeks
Monitoring Protocol:
| Week | Symptom Tracking | Adjustments |
|---|---|---|
| 1-2 | Daily symptom diary | Increase HCl if needed |
| 3-4 | Assess die-off reactions | Add binders if severe |
| 5-6 | Evaluate improvement | Continue if progressing |
| 7 | Rest week assessment | Plan retest timing |
| 8 | Retest breath test | Extend if still positive |
Managing Herxheimer (Die-Off) Reactions:
When antimicrobial treatment kills bacteria rapidly, toxins released can temporarily worsen symptoms. This “die-off” reaction indicates treatment is working but requires management:
Symptoms of Die-Off:
- Increased fatigue and brain fog
- Temporary worsening of bloating/gas
- Headaches, body aches
- Skin breakouts, rashes
- Mood changes, irritability
Die-Off Management Strategies:
- Activated Charcoal: 500mg, 2-3x daily (2 hours away from medications/supplements)
- Bentonite Clay: 1 tsp in water, once daily
- Increase Water Intake: Minimum 8-10 glasses daily
- Epsom Salt Baths: 2 cups in warm bath, 20 minutes, 3x weekly
- Slow Protocol Progression: If severe, reduce antimicrobial dosage temporarily
Phase 3: Motility Restoration (Ongoing)
The Critical Missing Piece in SIBO Treatment
Research consistently shows that impaired migrating motor complex (MMC) function is present in 70-80% of SIBO cases. The MMC is your gut’s “housekeeper,” sweeping bacteria from the small intestine into the colon between meals. Without proper MMC function, SIBO recurrence is almost inevitable.
Natural Prokinetic Protocol:
- Iberogast (STW-5): 20 drops, 3x daily before meals
- Nine-herb formula with strongest evidence
- Improves MMC function
- Reduces visceral hypersensitivity
- Safe for long-term use
- Ginger Root Extract: 250mg, 2x daily
- Accelerates gastric emptying
- Natural antiemetic
- Anti-inflammatory properties
- MotilPro (5-HTP + Ginger combination): 2 capsules at bedtime
- Supports serotonin production (90% made in gut)
- Enhances nighttime MMC activity
- Improves bowel regularity
Lifestyle Factors for MMC Support:
✅ Meal Spacing: 4-5 hours between meals (no snacking)
✅ Overnight Fast: 12-14 hours minimum
✅ Light Exercise: 30-minute walk after dinner
✅ Stress Management: Vagal tone exercises, meditation
Phase 4: Rebuild and Restore (2-6 Months)
Objective: Restore healthy gut microbiome and prevent recurrence
Strategic Probiotic Reintroduction:
Timing Matters: Wait until 4 weeks post-antimicrobial treatment and confirmed negative breath test before introducing probiotics. Premature probiotic use can feed SIBO and prevent eradication.
Recommended Probiotic Strategy:
- Soil-Based Organisms (SBOs) – First choice for SIBO
- Bacillus strains: Bacillus coagulans, B. subtilis
- Spore-forming, survive stomach acid
- Don’t colonize small intestine
- Support immune function
- Start: 1 capsule every other day, gradually increase
- Saccharomyces boulardii – Beneficial yeast
- 5 billion CFU daily
- Doesn’t contribute to bacterial overgrowth
- Anti-inflammatory effects
- Supports intestinal barrier
- Traditional Lactobacillus/Bifidobacterium – Add last
- Only after 8-12 weeks of other probiotics
- Start with low-CFU formulas (10-25 billion)
- Gradually increase if well-tolerated
- Some SIBO patients never tolerate high doses
Prebiotic Fiber Introduction:
Start Low, Go Slow Approach:
| Week | Fiber Type | Amount | Foods |
|---|---|---|---|
| 1-2 | Soluble fiber | 2-3g daily | Well-cooked carrots, zucchini |
| 3-4 | PHGG | 3-5g daily | Partially hydrolyzed guar gum supplement |
| 5-6 | Resistant starch | 1-2 tsp | Cooked and cooled potatoes |
| 7-8 | Inulin (if tolerated) | 2-3g | Small amounts of asparagus, artichoke |
Supporting Gut Barrier Integrity:
- L-Glutamine: Continue 5-10g daily for 3-6 months
- Zinc Carnosine: 75mg, 2x daily
- Omega-3 Fatty Acids: 2-3g combined EPA/DHA daily
- Collagen Peptides: 10-20g daily
Dietary Strategies for SIBO Treatment
The SIBO-Specific Diet Approach
Unlike generic “gut health” diets, SIBO dietary management requires precision. The goal is to starve bacterial overgrowth while maintaining adequate nutrition and supporting treatment efficacy.
Low-FODMAP Diet for SIBO
FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols—carbohydrates that bacteria ferment, producing the gas and bloating characteristic of SIBO.
Phase 1: Strict Low-FODMAP (4-6 weeks during antimicrobial treatment)
✅ Foods to Emphasize:
Proteins:
- Chicken, turkey, fish, seafood
- Eggs (if tolerated)
- Firm tofu (small amounts)
- Beef, lamb, pork (grass-fed preferred)
Vegetables (well-cooked):
- Carrots, zucchini, squash
- Green beans, cucumber
- Eggplant (without skin)
- Bok choy, lettuce
- Bell peppers (small amounts)
Fruits (limited):
- Blueberries, strawberries (1/2 cup max)
- Cantaloupe, honeydew (small amounts)
- Firm banana (not overripe)
- Kiwi (firm), grapes (15 max)
Grains & Starches:
- White rice, rice noodles
- Quinoa (small amounts)
- Sourdough spelt bread (fermented >24 hours)
- Gluten-free oats (if tolerated)
Fats:
- Olive oil, avocado oil
- Coconut oil (small amounts)
- Macadamia nuts (10-15 nuts)
- Small amounts aged cheese (if dairy tolerated)
❌ Foods to Avoid During Treatment:
High-FODMAP Vegetables:
- Onions, garlic, leeks
- Cauliflower, broccoli, cabbage
- Mushrooms, asparagus
- Sugar snap peas, beans, lentils
High-FODMAP Fruits:
- Apples, pears, stone fruits
- Watermelon, dried fruits
- Mango, cherries, blackberries
Grains to Avoid:
- Wheat, rye, barley
- Chickpea flour, lentil pasta
Other Triggers:
- Honey, agave, high-fructose corn syrup
- Sugar alcohols (sorbitol, mannitol, xylitol)
- Inulin, chicory root
- Most dairy products
Specific Carbohydrate Diet (SCD) for SIBO
Some practitioners and patients find the Specific Carbohydrate Diet even more effective than low-FODMAP for SIBO treatment. SCD eliminates all complex carbohydrates and disaccharides, allowing only monosaccharides.
SCD Legal Foods:
- Fresh meats, fish, eggs
- Most vegetables (except potatoes, yams)
- Most fruits (no dried, no high-sugar)
- Nuts and nut butters (almonds best)
- Aged cheeses (24+ months)
- Homemade yogurt (fermented 24 hours)
- Honey (natural sweetener)
SCD Illegal Foods:
- All grains (including rice, corn)
- All starches and flours
- Potatoes, yams, parsnips
- Sugar, maple syrup, molasses
- All processed foods
- Margarine, commercial yogurt
The Elemental Diet: Aggressive SIBO Reset
For severe SIBO cases or treatment-resistant overgrowth, a 2-3 week elemental diet can achieve up to 80% SIBO eradication. This medical food approach provides predigested nutrients that are absorbed in the upper small intestine, literally starving bacteria in the lower small intestine.
How Elemental Diet Works:
- Amino acids (not whole proteins) – absorbed immediately
- Simple sugars (dextrose, maltodextrin) – absorbed rapidly
- Minimal fat – medium-chain triglycerides
- No fiber – nothing to ferment
- Complete nutrition in liquid form
Elemental Diet Protocol:
- Replace all food with elemental formula for 14-21 days
- Consume 6-8 shakes daily (approximately 1,800-2,000 calories)
- Drink additional water, herbal teas
- Optional: Continue low-dose herbal antimicrobials
- Monitor symptoms (usually improve within 3-5 days)
Pros: Fast results, complete bowel rest, high success rate
Cons: Challenging compliance, expensive, socially isolating, taste issues
Who Benefits Most:
- Multiple failed treatment attempts
- Severe symptoms affecting quality of life
- Need rapid improvement for upcoming events
- Preparing for ileocecal valve surgery
- Jump-start before transitioning to SCD
Testing and Monitoring: The Data-Driven Approach
SIBO Breath Testing: What You Need to Know
Lactulose vs. Glucose Breath Tests:
Both tests measure hydrogen and methane gases produced by bacteria, but differ in what they reveal:
| Test Type | What It Detects | Advantages | Disadvantages |
|---|---|---|---|
| Lactulose | Full small intestine + colon | Reaches all areas of SI | False positives from rapid transit |
| Glucose | First 3-5 feet of SI only | More specific, fewer false positives | Misses distal SIBO |
Interpreting Your Breath Test:
Positive for Hydrogen SIBO:
- Rise of 20+ ppm hydrogen above baseline within 90 minutes
- Peak usually occurs at 60-90 minute mark
Positive for Methane (IMO):
- Methane levels >10 ppm at any time point
- Often elevated throughout entire 3-hour test
Positive for Hydrogen Sulfide:
- Often shows flat line (negative) on standard test
- High clinical suspicion based on symptoms
- May need specialized testing
When to Retest:
- Baseline: Before starting treatment
- Post-treatment: 4 weeks after completing antimicrobials
- Follow-up: 3-6 months if symptoms recur
Comprehensive SIBO Workup
Beyond breath testing, a thorough SIBO evaluation includes additional diagnostics to identify root causes and complications:
Essential Testing Panel:
- Comprehensive Stool Analysis (GI-MAP or similar)
- Identifies parasites, pathogenic bacteria
- Assesses pancreatic enzyme function
- Measures inflammation markers (calprotectin)
- Evaluates beneficial bacteria levels
- Food Sensitivity Testing
- IgG food antibody panel
- Identifies inflammatory triggers
- Guides dietary elimination
- Organic Acids Test
- Assesses nutritional deficiencies
- Identifies fungal overgrowth
- Evaluates mitochondrial function
- Thyroid Panel (comprehensive)
- TSH, Free T3, Free T4, Reverse T3
- Thyroid antibodies (TPO, TG)
- Hypothyroidism common with SIBO
Advanced Testing (if indicated):
- Small bowel imaging: MRI enterography, CT enterography
- Gastric emptying study: If suspecting gastroparesis
- Ileocecal valve assessment: Physical exam, imaging
- Secretory IgA: Immune function in gut
South Florida Environmental Factors
How Our Climate Impacts SIBO Treatment
Living in South Florida presents unique challenges for gut health and SIBO management. Understanding these regional factors helps optimize treatment outcomes:
High Humidity and Mold Exposure:
South Florida’s average humidity of 75% creates ideal conditions for mold growth. Research shows mold exposure can:
- Increase intestinal permeability (leaky gut)
- Suppress immune function
- Create chronic inflammation
- Worsen SIBO symptoms
- Contribute to histamine intolerance
Mold-Related SIBO Complications:
- Resistant overgrowth (doesn’t respond to standard treatment)
- Elevated histamine symptoms (flushing, headaches, anxiety)
- Multiple chemical sensitivities
- Chronic fatigue alongside gut symptoms
Addressing Mold in SIBO Treatment:
- Environmental assessment: Professional mold testing of home/workplace
- Binders during treatment: Activated charcoal, bentonite clay, chlorella
- Glutathione support: N-acetylcysteine (NAC) 1,200mg daily
- Air purification: HEPA filters in bedrooms, living areas
Heat and Digestive Function:
South Florida’s year-round heat affects SIBO management through:
- Dehydration impact: Concentrated stomach acid, impaired motility
- Appetite suppression: Inadequate protein intake common
- Food safety concerns: Bacterial contamination risk in warm climate
- Exercise limitations: Outdoor activity restrictions affect motility support
Climate-Adapted Protocol Adjustments:
- Increase electrolyte intake (minerals, coconut water)
- Indoor exercise options during peak heat
- Careful food storage, preparation practices
- Consider swimming as gentle motility support

Frequently Asked Questions
Q: How long does it take to treat SIBO naturally?
Most patients require 4-12 weeks of antimicrobial treatment, with hydrogen SIBO typically responding in 4-6 weeks and methane IMO requiring 8-12 weeks. However, comprehensive SIBO treatment including root cause correction and microbiome restoration takes 6-12 months for complete resolution.
Q: Can I treat SIBO without antibiotics?
Yes. Research demonstrates that herbal antimicrobials achieve comparable or superior results to pharmaceutical antibiotics, with 46% eradication rates that increase to 85% when combined with dietary modifications and motility support. Natural protocols often have fewer side effects and lower recurrence rates.
Q: Why do probiotics make my SIBO worse?
Standard probiotics containing Lactobacillus and Bifidobacterium can worsen SIBO symptoms by adding more bacteria to an already overgrown small intestine. Wait until after successful SIBO eradication (4+ weeks post-treatment) before introducing probiotics, and start with soil-based organisms rather than traditional strains.
Q: Will SIBO go away on its own?
No. SIBO rarely resolves without treatment because the underlying factors that caused bacterial overgrowth (impaired motility, low stomach acid, etc.) persist. Without addressing root causes and reducing bacterial load, symptoms typically worsen over time and can lead to complications like nutrient deficiencies and intestinal damage.
Q: Can stress cause SIBO?
While stress alone doesn’t directly cause SIBO, it significantly impairs the migrating motor complex (MMC) that prevents bacterial overgrowth. Chronic stress reduces stomach acid production, slows gut motility, and disrupts the gut-brain axis—all factors that contribute to SIBO development and recurrence.
Q: Is SIBO the same as IBS?
No, but they’re closely related. Research shows that 60-78% of IBS patients actually have underlying SIBO. IBS is a syndrome (collection of symptoms), while SIBO is a specific condition with measurable bacterial overgrowth. Many IBS patients find complete symptom resolution after proper SIBO treatment.
Q: What’s the difference between SIBO and Candida overgrowth?
SIBO involves bacterial overgrowth in the small intestine, while Candida overgrowth involves fungal/yeast proliferation (usually in the colon but can affect small intestine). They can occur simultaneously and share similar symptoms. Comprehensive stool testing helps differentiate between the two conditions.
Q: Can I exercise during SIBO treatment?
Yes, gentle exercise actually supports SIBO recovery by promoting gut motility. Walking, swimming, and light yoga are ideal. Avoid intense exercise during the first 2 weeks of antimicrobial treatment if experiencing severe die-off reactions. In South Florida’s heat, choose morning or evening outdoor activity, or exercise indoors.
Q: How much does natural SIBO treatment cost?
DIY herbal protocol costs approximately $200-400/month for 2-3 months of treatment, plus $200-300 for breath testing. Working with a functional medicine practitioner adds $300-800 for initial consultation and $150-300 for follow-ups. Compare this to repeated antibiotic courses at $100-300 each with higher recurrence rates.
Q: Will I have to avoid high-FODMAP foods forever?
No. Low-FODMAP diet during treatment (4-6 weeks) significantly improves success rates, but it’s not intended as a permanent diet. After successful SIBO eradication and gut microbiome restoration, most patients can reintroduce high-FODMAP foods gradually and tolerate a varied diet with some personal modifications.
Conclusion: Your Path to Lasting Gut Health
SIBO natural treatment options offer effective, evidence-based solutions that address root causes rather than simply suppressing symptoms. As someone who transitioned from oncology to functional medicine, I’ve witnessed countless patients achieve complete SIBO resolution using the protocols outlined in this guide.
The key to success lies in a comprehensive approach that combines:
✅ Evidence-based herbal antimicrobials targeting your specific SIBO subtype
✅ Strategic dietary modifications reducing fermentation and symptoms
✅ Motility restoration preventing recurrence
✅ Root cause correction addressing underlying dysfunction
✅ Microbiome rebuilding establishing long-term gut health
✅ Environmental awareness managing South Florida-specific factors
While the journey requires commitment and patience, the results—freedom from chronic bloating, gas, pain, and food restrictions—make the effort worthwhile. Most patients experience significant symptom improvement within 4-8 weeks, with continued gains over the following months.
Whether you choose to pursue treatment independently or work with a functional medicine practitioner, the most important step is beginning your journey. Your gut health affects every aspect of your wellbeing, from energy and mood to immune function and chronic disease prevention.
