Effect of MED-02 Containing Two Probiotic Strains, Limosilactobacillus fermentum MG4231 and MG4244, on Body Fat...

MED-02 is a complex supplement containing two probiotic strains, Limosilactobacillus fermentum MG4231 and MG4244, isolated from humans. The anti-obesity effects and safety profile of MED-02 were assessed in overweight and obese subjects. In this randomized, double-blinded, placebo-controlled, multicenter study, 100 healthy obese and overweight subjects aged 19-65 years with a body mass index (BMI) between 25 and 31.9 kg/m² were recruited and randomized to receive a placebo or MED-02 (5 × 10⁹ CFU/day). After 12 weeks of consumption, body fat mass (-1166.82 g vs. -382.08 g; p = 0.024) and body fat percentage (-0.85% vs. -0.11%; p = 0.030), as evaluated by dual-energy X-ray absorptiometry (DEXA) and body weight (-2.06 kg vs. -1.22 kg; p = 0.041), were significantly reduced in the MED-02 group compared to the placebo group. The safety profile did not differ among the groups. No serious adverse effects were observed in either group. These results suggest that MED-02 is a safe and beneficial probiotics that reduces body fat and body weight in overweight or obese individuals.
