Overview
Brief Summary
The goal of this placebo-controlled randomized trial is to test the effect of intervention with Bifidobacterium animalis subsp. lactis BLa80 on the composition of the gut microbiota of healthy volunteers. The main question it aims to answer is whether probiotic can effectively regulate intestinal flora. Participants will take a package of probiotics every day, and their weight was recorded once a week using a weight scale. Blood and stool tests were conducted before and after taking probiotics.
Detailed Description
This placebo-controlled study aims to investigate the effect of Bifidobacterium animalis subsp. lactis BLa80 supplementation on the status of the gut microbiota of healthy participants. 112 subjects were randomly divided into a placebo group (maltodextrin) and a Bla80 group (maltodextrin + strain BLa80 in 1 × 10 10 colony-forming units/day). The intervention lasted 8 weeks, and 16S rRNA sequencing technology was used to study the changes in gut microbiota between different groups. Simultaneously, clinical indicators such as alanine transaminase (ALT), aspartate aminotransferase (AST), and uric acid (UC) were measured to illustrate the metabolic effects of BLa80.
