Nästa generations synbiotika hos individer med övervikt eller fetma

28 september 2026 uppdaterad av: Elisa Marroquin, Texas Christian University

Komplettering med nästa generations synbiotika hos individer med övervikt eller fetma: en trippelblindad randomiserad kontrollerad klinisk prövning

This study plans to evaluate the effect of consuming a symbiotic (probiotic + prebiotic) for 3 months on body weight, body composition, glucose sensitivity, and psychological parameters, as well as on gut and blood microbial composition. Synbiotic consumption is preceded by a 3-day antibiotic course to help ensure the opening of new niches (houses) for the upcoming beneficial bacteria.

Detaljerad beskrivning

This is a triple-blinded, randomized clinical trial in which participants will be allocated to one of two groups: 1) 3-day antibiotic followed by synbiotic consumption for 3 months or 2) 3-day antibiotic followed by placebo consumption for 3 months.

Blood and stool samples will be collected before the antibiotic, and before and after the symbiotic intervention in both groups.

Gut microbial composition will be analyzed through whole genome sequencing and blood microbial composition through 16S rRNA.

Glucose sensitivity will be measured through fasting glucose, fasting insulin, and HbA1c.

Body composition through DXA and BodPod will be measured before and after the symbiotic intervention.

Psychological questionnaires such as the Beck Anxiety and the Beck Depression Inventories, as well as the RED-9 questionnaire to respectively measure anxiety, depression, and food cravings, will be applied before and after the symbiotic intervention.

The synbiotic that will be used in this trial contains the oligosaccharide-degrading probiotics, Akkermansia muciniphila and Bifidobacterium infantis; butyrate producers such as Clostridium beijerinckii, Anaerobutyricum hallii, and Clostridium butyricum; and chicory-derived inulin, a prebiotic dietary fiber.
Kosttillskott: Synbiotic Group

WBF-038: Noninfectious and nonhazardous lyophilized commensal bacteria (probiotics). Contains no genetically modified organisms (GMOs) and contains no animal ingredients or by-products, and were originally isolated from human sources. The (probiotic) strains are grown in a FDA registered food facility, adhering to Good Manufacturing Practice (GMP) conditions.

Probiotic Ingredients:

Clostridium butyricum WBSTR-0006, Clostridium beijerinckii WB-STR-0005, Anaerobutyricum hallii WB-STR-0008, Akkermansia muciniphila WBSTR-0001, and Bifidobacterium infantis

The product also contains: Chicory inulin and oligofructose (prebiotic fiber), hypromellose (vegetarian capsule), fruit & vegetable juice (coloring agent), magnesium stearate and silica (flow agent for encapsulation)
