Hormonal

Lactobacillus sp. supplementation significantly decreases leptin levels and increases adiponectin levels in non-comorbid obese individuals.

Lactobacillus supplementation may help improve your hormonal profile by lowering leptin (which can promote fat storage) and raising adiponectin (which improves insulin sensitivity and fat burning). This hormonal shift supports weight management efforts.

Leptin levels significantly decreased (MD: -2.11 μg/mL; 95%CI: -3.59–(-0.64), p=0.005) compared to before Lactobacillus sp. supplementation, while adiponectin levels increased (MD: 0.71 μg/mL; 95%CI: 0.22–1.20, p=0.004) following Lactobacillus sp. supplementation compared to placebo group.
