Dr. Kumar’s Take:
A recent double-blind clinical trial provides compelling evidence that probiotics may help alleviate postural imbalance and reduce disease severity in patients with knee osteoarthritis (OA). This study highlights the growing importance of the gut-joint axis and the role of intestinal health in managing musculoskeletal conditions. For those suffering from OA, adding a high-quality probiotic supplement may be a worthwhile strategy to complement conventional treatments.
Brief Summary:
This 12-week randomized, double-blind, placebo-controlled study investigated the effects of a multistrain probiotic on 147 patients suffering from knee OA. The probiotic group showed significant improvements in postural balance, pain reduction, handgrip strength, and walking speed. Biomarker analysis revealed that these benefits were associated with decreased plasma zonulin (a marker of intestinal permeability) and reduced inflammation, suggesting that probiotics may help repair gut barrier function and lower systemic inflammation in OA patients.
Key Takeaways:
✔ Probiotics reduced pain severity and improved overall function in knee OA patients.
✔ Postural balance and gait speed significantly improved with probiotic use.
✔ Probiotics lowered plasma zonulin and CRP levels, suggesting improved gut barrier integrity and reduced systemic inflammation.
✔ No major side effects were reported.
Study Design:
This was a 12-week, double-blind, placebo-controlled clinical trial involving 147 patients with knee OA (age range: 64–75 years). Participants were randomly assigned to receive either a multistrain probiotic (Vivomix 112 billion CFUs) or a placebo. The study measured pain intensity, balance control, handgrip strength, gait speed, and inflammation markers.
Results:
✔ Pain intensity and disease severity decreased significantly in the probiotic group.
✔ Balance scores improved, particularly in patients with moderate to severe OA.
✔ Handgrip strength and walking speed increased, reflecting better functional capacity.
✔ Plasma zonulin and C-reactive protein (CRP) levels decreased, indicating a reduction in gut leakiness and inflammation.
✔ No significant change was observed in knee range of motion or oxidative stress markers.
The Gut-Joint Axis and Osteoarthritis
The gut microbiome plays a crucial role in immune regulation and systemic inflammation. Increased intestinal permeability (“leaky gut”) can contribute to chronic inflammation, exacerbating joint degeneration in OA. By improving gut barrier function, probiotics may help reduce inflammation and enhance musculoskeletal health.

Frequently Asked Questions
How long does it take for probiotics to show results in OA?
In this study, improvements were observed after 12 weeks of daily supplementation. Individual results may vary.
Are there any side effects of taking probiotics for OA?
No major adverse effects were reported in this study. However, minor digestive adjustments (such as mild bloating) are possible when starting a probiotic regimen.
What type of probiotic was used in the study?
The study used Vivomix 112 billion CFUs, a high-potency multistrain probiotic containing Lactobacillus and Bifidobacterium species.
Can probiotics replace traditional OA treatments?
No, probiotics should be considered a complementary approach rather than a replacement for standard OA treatments like physical therapy, exercise, and medications.
Conclusion:
This groundbreaking study suggests that probiotic supplementation may offer a novel approach to improving postural balance in knee osteoarthritis patients. By potentially modulating gut microbiota and reducing systemic inflammation, probiotics could complement existing OA treatments and help reduce fall risk. While these results are promising, larger clinical trials are needed to confirm efficacy, determine optimal probiotic formulations, and identify which patient populations might benefit most from this intervention.
