If you suffer from Irritable Bowel Syndrome (IBS), you can get relief. 


Elemental diets are clinically proven to help patients reduce severe GI distress in a matter of days.

An elemental diet is a temporary liquid diet that provides essential nutrients in their purest, most “elemental” forms. The nutrients absorb directly into your system with almost no digestion needed, allowing the GI tract to rest and recover.

During this time, your small intestine also has a chance to starve off excess bacteria that may be causing your IBS distress and discomfort.

Studies indicate that gut bacteria overgrowth can cause symptoms of IBS, specifically “Small Intestinal Bacterial Overgrowth,” or SIBO for short.

  • You might have SIBO if you:

    • Feel bloating and/or brain fog within two hours of eating and have chronic diarrhea or constipation (or alternate between them)
    • Have frequent belching and gas, and find yourself “running to the bathroom” 
    • Have food sensitivities and feel worse after ingesting added fiber
    • Had food poisoning and your gut has never been the same since
    • Have low B12 that cannot be explained by another cause 
    • Have been diagnosed with IBS
  • If you suspect that you have SIBO, or that bacterial overgrowth is making your IBS worse, there is good news. Elemental diets are a natural way to get GI relief and start living life again.

  • In fact, across the last 50 years, hundreds of clinical studies have demonstrated the effectiveness of elemental diets for relieving the symptoms of chronic and severe GI conditions, like IBS and SIBO.²

  • Most recently, in a 2023 clinical trial at Cedars-Sinai in Los Angeles, 83% of patients who finished two weeks of exclusive elemental diet experienced symptom improvement, and reported feeling better.³

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.

    Unlock the power of medical nutrition

    An elemental diet is a short-term liquid diet that provides comprehensive nutrition in its purest, most “elemental” form. Composed of proteins, fats, and carbohydrates in their simplest forms, elemental diets are easily absorbed into the first 2-4 feet of the small intestine with almost no digestive effort. This allows the gut to rest, recover, and starve off excess bacteria causing distress and inflammation.

    There are no “magic ingredients” in an elemental diet. In fact, the absence of ingredients is what gives the body a break. Elemental diets provide your body with what it needs to function and nothing more – no additives, no allergens, no distractions.

    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.
