Based on the information available to me, Pillser's research database does not contain specific studies on Lactobacillus rhamnosus R0011 and its effect on diarrhea duration. The database has one study on Lactobacillus rhamnosus (broadly) and diarrhea, which showed a beneficial effect, but that study used a different strain (L. johnsonii M5) in an animal model, not the R0011 strain in humans¹.

That said, drawing from general knowledge on this topic:

Lactobacillus rhamnosus R0011 (also known as L. rhamnosus Rosell-11) is a probiotic strain that is often studied in combination with Lactobacillus helveticus R0052. While the well-known L. rhamnosus GG strain has strong evidence for reducing the duration of acute infectious diarrhea in children, the evidence for the R0011 strain specifically is less robust.

Some clinical research suggests that L. rhamnosus R0011 (especially in multi-strain formulations) may help with:

• Antibiotic-associated diarrhea – potentially reducing incidence and duration.
• Acute diarrhea in children – But the strongest evidence remains with L. rhamnosus GG, not R0011 specifically.

Overall, while Lactobacillus rhamnosus as a species has been shown to be beneficial for reducing diarrhea duration, the specific R0011 strain has less high-quality evidence behind it for this particular outcome compared to other strains like GG. You may want to look specifically for products that contain well-studied strains for diarrhea if that is your goal.

Would you like me to search for probiotic products containing Lactobacillus rhamnosus on Pillser?
