About this study
Official title: A Randomized, Double-blind, Placebo-controlled Study to Evaluate the Effect of SlimBiotics L. Fermentum K8 Postbiotic on Weight Management and Metabolic Health Outcomes
This study is to evaluate the efficacy of a postbiotic supplement on weight management and metabolic health. This study will be conducted as a hybrid trial consisting of both in-person visits and virtual assessments. Two groups will be included: the intervention (SlimBiotics postbiotic) and placebo.
The SlimBiotics postbiotic formula is the first plant-based postbiotic targeting weight management and metabolic health. Other competing postbiotics are isolated from humans (feces) but the strains in SlimBiotics were isolated from a fermented plant (millet porridge cereal)
This product contains L. fermentum K8 Postbiotic.
- Conditions
- Metabolic Health, Weight Loss, Stress, Well-Being, Psychological, Sleep, Healthy Eating
- Being tested
- Slimbiotics Postbiotic, Placebo
