Suffering from SIBO or IMO? Better days are possible.


Elemental diets are clinically proven to help patients reduce symptoms of GI distress and eradicate disruptor bacteria contributing to Small Intestinal Bacterial Overgrowth (SIBO) and Intestinal Methanogen Overgrowth (IMO) in a matter of days.

An elemental diet is a temporary liquid diet that provides essential nutrients in their purest, most “elemental” forms. Proteins, fats, and carbohydrates absorb into the first 2-4 feet of the small intestine with almost no digestive effort, allowing your gut to rest, recover, and starve off the excess bacteria that may be causing your distress and discomfort.


Elemental diets give your body a break by nourishing it with what it needs to function and nothing more – no additives, no allergens, no distractions. It’s a natural, nutritional way for patients to fight back against SIBO and IMO and start living life again.

  • While the efficacy of antibiotics for SIBO and IMO hover around 50% or less, a 2023 clinical trial at Cedars-Sinai in Los Angeles put mBIOTA Elemental™ to the test for patients with SIBO, IMO, and a combination of both. The results were undeniable: 

  • The mBIOTA Elemental™ diet was 83% successful in eradicating SIBO overall, across all patient types.  

  • These findings support hundreds of other clinical studies (across five decades) that have also found that elemental diets can relieve symptoms of GI conditions like IMO and SIBO.²

Relief is within your reach

Even when SIBO and IMO patients do not fully enter remission, they can feel relief by taking a course of elemental diet. In the same clinical trial, 80% of patients who finished two weeks of exclusive elemental diet experienced symptom improvement and reported feeling better.

    Clinically effective symptom reduction

    Trial participants on average reported up to a 65% reduction in the 12 most common symptoms of GI disorders

    And when researchers followed up two weeks after the diet was completed, patients continued to report improved symptoms. Their relief had staying power.

    • We’ve known for a long time that elemental diets work. However, they used to taste so bad that people refused to drink them, so doctors stopped considering them a viable option. But not anymore…

    The mBIOTA Elemental solution

    An easily drinkable elemental diet is here

    Perfected in two flavors, Original Tropical Vanilla and Orange, the truly palatable taste transforms the patient experience. In the same clinical study, patients overwhelmingly preferred the taste of mBIOTA Elemental™ to the market leading competitor on all taste metrics:

    • Overall impression and appearance
    • Taste and aftertaste
    • Smell and consistency
    • Just a few years ago, Krystyna Houser found herself in a place that you may be familiar with: struggling with the debilitating effects of a GI disorder. The constant discomfort, the endless visits to doctors, and the frustration of not finding relief were overwhelming and exhausting.

      In her quest for answers, she met two pioneering gastroenterologists, Dr. Mark Pimentel and Dr. Ali Rezaie, who taught her about elemental diets. She felt hope for the first time in a long time, and decided to give one a try. It tasted horrendous.

      Krystyna was desperate for relief, but drinking something so unpleasant made an already hard situation even more daunting. She knew there had to be a better way. 

      Krystyna Houser founded mBIOTA Labs to pursue better solutions for other people like her who suffered from debilitating GI issues. 

      Partnering with Dr. Pimentel, Dr. Rezaie, and food scientists, she set out on a mission to create an elemental diet that was not only effective, but tasted good too.

    Better Taste, Better Results

    Unlock the power of medical nutrition

    A typical course of an exclusive elemental diet ranges from 2-4 weeks but it can also be used to provide supplemental nutrition in various durations. The duration of the diet will depend on your symptoms and the individual recommendations made by your health professional.

    mBIOTA Elemental™ was the formula successfully used in the 2023 clinical trial at Cedars-Sinai Los Angeles where 80% of patients reported improvement in symptoms, and 83% of patients successfully eradicated their SIBO. 100% of trial participants made it to the end, finishing two weeks of exclusive mBIOTA Elemental™. This has never been accomplished by any other elemental diet product.

    Relief is possible for you, too.
