Synbiotic-Containing Bacillus coagulans (GBI-30) and the Effects on Glycemic Control, Androgen Hormones and Anthropometric Indices in Women with Polycystic Ovarian Syndrome.

BACKGROUND

We aimed to investigate the effect of synbiotic supplement-containing spore-forming Bacillus coagulans (GBI-30) on the glycemic, hormonal and anthropometric parameters in patients with PCOS.

METHODS

In this randomized, triple-blind, placebo-controlled trial, 72 patients with PCOS were randomly and equally assigned to receive a daily sachet of synbiotic (containing Bacillus coagulans (GBI-30), Lactobacillus rhamnosus, Lactobacillus helveticus, and fructooligosaccharide (FOS)) or placebo for 12 wk. Glycemic, hormonal and anthropometric parameters were measured at baseline and after the 12-week of intervention.

RESULTS

At the end, 60 patients completed the study. After adjustment for potential confounders, significant decrease in insulin (-3.38±20.20 vs. +2.33, P=0.042), homeostatic model assessment for insulin resistance (HOMA-IR) (-0.43±3.61 vs. +0.73 ± 2.91, P=0.044) and dehydroepiandrosterone sulfate (DHEAS) (-1.47±6.62 vs. + 0.03 ± 2.06, P=0.047) was observed in the intervention group compared to the control group. Supplementation with synbiotic failed to show a significant effect on anthropometric parameters and fasting blood sugar.

CONCLUSION

Overall, 12 wk supplementation with synbiotic-containing Bacillus coagulans (GBI-30) can offer additional benefit to lifestyle intervention on metabolic status of women with polycystic ovarian syndrome.
