ELEMENTAL DIET FOR SIBO

Managing SIBO or IMO? A better way forward is possible.

Living with SIBO (Small Intestinal Bacterial Overgrowth) or IMO (Intestinal Methanogen Overgrowth) can feel discouraging, especially when symptoms continue despite diet changes or treatment attempts. If bloating, discomfort, or food intolerance have become part of your daily life, you are not alone.

mBIOTA Elemental provides a clinically proven solution.

What Is Sibo / IMO?

SIBO and IMO happen when microorganisms build up in the small intestine and interfere with digestion and nutrient absorption.

These organisms ferment food particles, producing gas and triggering digestive symptoms. For many people, this leads to cycles of food restriction and uncertainty about what will actually help. Elemental nutrition offers a simple, comprehensive source of nourishment that gives your body a break from active digestion and supports you through SIBO or IMO so you can thrive again.

Common SIBO Symptoms INCLUDE
  • Bloating
  • Diarrhea
  • Constipation
  • Abdominal Pain
  • Brain Fog
  • Fatigue
  • Gas
  • Bathroom Urgency
  • Distention
  • Discomfort After Eating
How does an elemental diet work for sibo?

An Elemental Diet is medical nutrition that provides complete nourishment while simultaneously starving the excess of microorganisms to achieve eradication of bacteria or archaea.

An Elemental Diet is a temporary, liquid nutrition therapy that provides essential nutrients in their purest, most "elemental" and easy-to-absorb forms. Because these proteins, fats, and carbohydrates are absorbed early in the small intestine, the rest of your digestive tract can rest and recover while limiting “fuel” for excess bacteria, or archaea, that typically cause distress and discomfort.

Elemental Diets are used in SIBO and IMO care to help calm digestive symptoms, often within days, by reducing the fuel bacteria rely on and limiting digestion.

Maintaining Your Results

Completing an elemental diet is a major step. What follows is just as important—reintroduce food gradually over 2 weeks using Low Fermentation Eating.

  • Days 1–2: Start Simple

    Begin with easily digestible foods like eggs, chicken, white rice, and potatoes. Keep portions small and expect mild shifts in digestion.

  • Days 3-4: Add Gentle Variety

    Introduce nondairy or lactose-free milk, hard-aged cheeses, well-cooked vegetables, sushi, avocado, and certain fruits like citrus or berries.

  • Days 5-6: Expand Your Plate

    Enjoy all LFE-approved fruits, but continue to hold off on raw vegetables. You can also reintroduce hot spices and moderate alcohol, if tolerated.

  • Days 7+: Slow & Steady

    Slowly introduce raw greens and red meat. Bring back personal trigger foods one at a time, watching for reactions. Wait a week before retrying anything that causes symptoms.
