Clinical Trial Summary

To evaluate the improvement in weight, body fat, and BMI after adding probiotics as a once-daily therapy for 84 days in overweight individuals.

Description:

The study product contains Lactobacillus delbrueckii subsp. Bulgaricus at a concentration of 1x10^8 CFU in each 100 mg. The objective of this study is to evaluate the benefits of probiotics as an add-on therapy in overweight individuals by assessing the improvements in weight, body fat, and BMI after adding probiotics as a once-daily therapy for 84 days. A randomized, two-regimen, placebo-controlled, parallel design is employed in this study, where each subject will receive either probiotics or a placebo. The add-on study product will be administered once daily for 84 days. The benefits will be assessed at baseline and subsequently on study days 28, 56, and 84, focusing on parameters such as weight, body fat, and BMI.
