Lactobacillus rhamnosus and Gestational Diabetes Risk

According to Pillser's research database, there is limited but promising evidence regarding the use of Lactobacillus rhamnosus probiotics for reducing the risk of gestational diabetes.

What the Research Shows

• 1 study has been cataloged in Pillser's database on this topic — a 2024 review paper¹.
• Effect type: The study found a beneficial effect, though the impact was described as small but statistically significant¹.
• The review noted that these probiotics may help prevent maternal obesity and gestational diabetes¹.

Key Considerations

• This is based on a single review paper, so the evidence base is still developing.
• Probiotics are generally considered safe during pregnancy, but you should always consult your healthcare provider before starting any new supplement regimen, especially during pregnancy.
• The effect size was small, meaning probiotics alone are unlikely to be a standalone solution for preventing gestational diabetes — they may be part of a broader strategy that includes diet, exercise, and medical monitoring.

Bottom Line

There is some early evidence suggesting Lactobacillus rhamnosus probiotics may have a beneficial role in reducing gestational diabetes risk, but more research is needed to confirm these findings and establish optimal dosing and timing.
