Evaluation of RSB11-HI Postbiotic Supplementation for Supporting Weight Management, Metabolic Wellness, and Quality of Life in Healthy Adults

26 de agosto de 2026 atualizado por: Able Biolabs, LLC

A Randomized, Double-Blind, Placebo-Controlled Clinical Trial to Evaluate the Safety and Efficacy of RSB11-HI Postbiotic Supplementation for Supporting Weight Management, Metabolic Wellness, and Quality of Life in Healthy Adults

This randomized, double-blind, placebo-controlled clinical trial will evaluate the safety, tolerability, and efficacy of RSB11-HI, a heat-inactivated postbiotic, in healthy adults over an 8-week intervention period. Participants will be classified into one of three predefined study populations-General Healthy, Perimenopausal, or Mild Inflammation-and will then be randomized within their assigned population to receive either RSB11-HI or placebo. The study will evaluate the effects of supplementation on healthy weight management, metabolic wellness, gastrointestinal health, and quality of life, while also exploring whether responses differ among the predefined study populations.

Descrição detalhada

This 8-week, randomized, double-blind, placebo-controlled, decentralized clinical trial will evaluate the safety, tolerability, and efficacy of RSB11-HI, a heat-inactivated postbiotic derived from *Lactiplantibacillus plantarum* RSB11, in healthy adults. Following eligibility screening, participants will be classified into one of three predefined study populations-General Healthy, Perimenopausal, or Mild Inflammation-and randomized within their assigned population to receive RSB11-HI or placebo. The study will evaluate potential effects on healthy weight management, metabolic wellness, gastrointestinal health, and quality of life, while exploratory analyses will assess treatment responses across the predefined study populations.

Change in Perceived Stress
Prazo: Baseline, Week 4, and Week 8
Change in perceived stress as assessed using the 10-item Perceived Stress Scale (PSS-10). Each item is rated from 0 (Never) to 4 (Very Often). The total score ranges from 0 to 40, with higher scores indicating greater perceived stress.
Baseline, Week 4, and Week 8
Change in Gastrointestinal Symptoms
Prazo: Baseline, Week 4, and Week 8
Change in gastrointestinal symptoms as assessed using the Gastrointestinal Symptom Rating Scale (GSRS). The questionnaire contains 15 gastrointestinal symptom items, each rated from 1 (No discomfort) to 7 (Very severe discomfort).

Change in menopause-related quality of life as assessed using the Menopause-Specific Quality of Life Questionnaire (MENQOL) in participants assigned to the Perimenopausal Wellness Population. The questionnaire assesses symptoms across vasomotor, psychosocial, physical, and sexual domains. For symptoms experienced, bother is rated from 0 (Not bothersome) to 6 (Extremely bothersome); participants may also indicate that a symptom was not experienced. Higher scores indicate greater symptom bother and worse menopause-related quality of life.
