Kluyveromyces lactis is a species of yeast widely used in the dairy industry for the production of cheese and fermented milk products, largely due to its ability to ferment lactose. There is growing scientific interest in the use of non-Saccharomyces yeasts, including K. lactis, as probiotics or as sources of beneficial molecules for gut health. Some laboratory and animal studies have shown that K. lactis can survive gastric transit and may interact with the gut microbiota. Additionally, its use in the production of β-galactosidase (lactase) has potential benefits for individuals with lactose intolerance, a condition affecting the small intestine. However, direct clinical evidence in humans for K. lactis as a probiotic supporting small intestine health is limited compared to more established probiotics like Saccharomyces boulardii or Lactobacillus species. Most of the scientific support centers on its enzymatic activity to help digest lactose, thereby reducing symptoms associated with lactose malabsorption in the small intestine. Overall, while there is a scientific rationale and some preliminary evidence for benefits to small intestine function—mainly regarding lactose digestion—the strength of evidence is modest and not as robust as for traditional probiotics.
