Common Questions

An elemental diet is a form of predigested liquid nutrition made from nutrients in their simplest form:  free amino acids, simple carbohydrates and easily-absorbed fats, vitamins, and minerals. Because it requires minimal digestive effort, nutrients are absorbed quickly, in the first few feet of the digestive tract, allowing the gut to rest, reducing inflammation, promoting mucosal healing and starving invasive bacteria. Typically used as sole source nutrition, elemental diets are a clinically validated therapeutic used to support conditions such as SIBO, Crohn’s disease, ulcerative colitis, GERD, EoE, constipation, diarrhea, and bloating.

mBIOTA Elemental is a clinically proven elemental diet, created in collaboration with leading gastroenterologists and food scientists. It delivers pure, easily absorbed nutrition through a fully vegan, gluten-free formula, enhanced by our proprietary Amino Taste Modification Technology to improve taste and tolerability. Unlike traditional elemental diets that are difficult to complete, mBIOTA is designed to be both clinically effective and genuinely drinkable, helping support GI conditions such as SIBO, IBS, Crohn’s, EoE, and more.

We’re proud to offer the best-tasting elemental diet, developed with flavor and the customer experience in mind. Original features a tropical vanilla profile with a subtle hint of coconut, often compared to coconut water, while Orange is commonly described as reminiscent of a Creamsicle. Both flavors are equally loved, with a mixed option available for those who prefer to alternate throughout the day.
