L. Acidophilus (Strain TW01) on Gut Health, Body Composition, and Inflammation
United States12 participantsStarted 2025-07-01
Plain-language summary
This is a pilot research study to investigate the effects of a probiotic supplement (L. acidophilus, strain TW01) on substances found in the stool and bloodstream, gut bacteria composition, body composition, as well as any relationship of these substances with markers of inflammation. Lactobacillus acidophilus is commonly found in a variety of fermented foods, including yogurt, cheese, and kefir, due to its ability to produce lactic acid and other substances. This bacterium is generally well-tolerated in healthy individuals and has a longstanding history of safe use. The investigators are doing this pilot study to see if a particular probiotic, called L. acidophilus (strain TW01) and isolated from fermented coffee grounds, can make a positive difference in human gut and overall health. Specifically, the investigators want to look at how this probiotic affects certain substances in human stool and blood, the makeup of the bacteria in the gut, and aspects of body composition. The investigators are also interested in whether these changes relate to markers of inflammation, which can tell us more about their impact on overall health. This probiotic strain has been shown in other studies to be safe and well tolerated, and the investigators hope our research will help us better understand how it works and whether it might support health in humans.
