Clinical trials

This randomized, double-blind, placebo-controlled trial will assess the clinical effects of probiotics in adults with functional constipation. Participants will receive probiotics or placebo for 8 weeks. The study will evaluate changes in bowel habits and symptom burden, as well as alterations in host inflammatory status, immune modulation, microbial ecosystem dynamics, neuroendocrine signaling related to the gut-brain axis, and systemic metabolic responses, to characterize the overall physiological impact of probiotic supplementation.

This study is a randomized, double-blind, placebo-controlled trial in which adult subjects with constipation are randomly assigned to either a probiotic group or a placebo group for an 8-week intervention. Through blood and fecal sample analyses combined with multidimensional questionnaire assessments, the study aims to systematically evaluate the efficacy of probiotics in improving gastrointestinal function, immune status, and mental health in patients with constipation.

This study aims to evaluate the efficacy and safety of Bifidobacterium animalis subsp. lactis BLa36 in adults with functional constipation. In this randomized, double-blind, placebo-controlled trial, participants will receive BLa36 supplementation or placebo for 8 weeks. Clinical outcomes will be assessed using validated gastrointestinal symptom scales, stool characteristics, and quality-of-life measures. In addition, changes in inflammatory and immune markers, gut microbiota composition, metabolic indicators, and gut-brain axis-related parameters will be evaluated to comprehensively determine the effects of BLa36 on intestinal function and overall health.

To evaluate the effects of probiotic intervention on gastrointestinal function in patients with constipation after 4 weeks of treatment, and to explore its potential effects on immune status and bone metabolism.

To evaluate the efficacy and safety of probiotic as a food supplement in regulating bowel habits in patients with chronic constipation, and to compare it with placebo.

To evaluate the impact of pasteurized Akkermansia muciniphila Akk11 capsules versus placebo on body composition (including body weight, BMI, body fat percentage, waist-to-hip ratio, wrist circumference, visceral fat area, and basal metabolic rate) and serum lipid parameters (TC, LDL-C, HDL-C, and TG) in overweight and obese adults.

Gut microbiota play a key role in polyphenol metabolism, participating in the breakdown of dietary components and producing various small molecule metabolites that affect human health. However, little is currently known about how gut microbes metabolize dietary compounds and produce bioactive metabolites. This study aims to use metabolomics to precisely identify food-derived metabolites in the blood to investigate whether probiotics (BLa80, LRa05) can enhance the breakdown of dietary components and improve their absorption and utilization in the human body.

To verify the improvement of gastrointestinal function in patients with non-organic gastrointestinal dysfunction after 4 weeks of intervention with compound probiotics.

This is a randomized, double-blinded, placebo-controlled study to evaluate the efficacy and safety of Akkermansia muciniphila Akk11 in healthy adult.

To evaluate the regulatory effect of Lactobacillus plantans Lp90 formula on visceral fat metabolism and sex hormone balance in obese women.

This project involves the use of oral Lactobacillus reuteri as an adjunct therapy for 8 weeks. Endoscopic observation of intestinal inflammation will be conducted at 1 month, 3 months, 6 months, and 12 months after the administration of the drug. Intestinal fluid will be collected endoscopically for 16S RNA analysis to assess changes in the gut microbiota. Inflammatory changes in the patients will be detected through peripheral blood tests, and fecal calprotectin levels will be measured to evaluate the progression of the disease.

This study aims to comprehensively evaluate the multifaceted impacts of Lactobacillus rhamnosus LRa05 on patients with gestational diabetes. Initially, the study will investigate the effects of LRa05 on improving patients' blood glucose levels and gut microbiota. Additionally, the study will assess the impact of this strain on patients' blood lipid levels, inflammatory markers, and body mass index (BMI). Furthermore, the study will also focus on its effects on thyroid function, vaginal microbiota, and bile acid metabolism in patients with gestational diabetes.

Evaluate the effectiveness and safety of Ligilactobacillus salivarius LS97 as a food supplement compared to a placebo in improving intestinal and immune functions in healthy adults.

Evaluate the efectiveness and safety of Bifidobacterium bifidum BBi32 as a food supplement compared to a placebo in improving intestinal andimmune functions in healthy adults.

This study aims to evaluate the safety and efficacy of the probiotic LH76 as a dietary supplement in healthy adults. The research will assess its effects on gut microbiota composition, intestinal health, and immune function compared to a placebo. Key outcomes include changes in microbial diversity, intestinal barrier integrity, and immune response markers over the intervention period. The findings will contribute to understanding the potential health benefits of LH76 and its role in supporting gut and immune health.

Evaluate the effectiveness and safety of Limosilactobacillus fermentum LF61 as a food supplement compared to a placebo in improving intestinal and immune functions in healthy adults.

The purpose of this study was to evaluate the regulatory effects of Huangqian-biobacteria compound preparation on liver health and related metabolic disorders in middle-aged and elderly people, observe its effects on liver function indexes, basal metabolic rate, markers of oxidative stress, inflammatory factors and intestinal microecology, and evaluate the incidence of adverse reactions in subjects during the 3-month intervention period.

Evaluate the effectiveness and safety of Bifidobacterium longum subsp. infantis BI45 as a food supplement compared to a placebo in improving intestinal and immune functions in healthy adults.

This study aims to evaluate the effect of a high-activity probiotic yogurt on improving symptoms of chronic constipation, observing its regulatory effects on the gut microbiota and the incidence of adverse reactions in study participants over a 21-day intervention period.

In this study, Lacticaseibacillus rhamnosus LRa05 was selected as test preparations to observe the clinical efficacy in the intervention trial of combined antibiotic therapy, and to evaluate its effects on the cure rate, recurrence rate and vaginal microbiota of patients with bacterial vaginitis.

The clinical trial aims to investigate the efficacy of Lactobacillus rhamnosus LRa05 in alleviating allergic rhinitis and its impact on the gut microbiota among 70 pediatric participants aged 4-12. The primary objective is to validate the improvement in allergic rhinitis symptoms following an 8-week intervention with Lactobacillus rhamnosus LRa05. Participants were instructed to consume the probiotic powder daily for approximately 8 weeks. At baseline, week 4, and week 8 endpoints, assessments of nasal symptoms, quality of life questionnaires, and stool samples for microbiota analysis were conducted on the participants, and blood samples were collected for immune-related factor testing.
