The central finding was that while the probiotic increased the abundance of Lacticaseibacillus species, it did not cause significant overall changes in gut microbiota diversity or composition compared to placebo.
The primary finding was that neither the placebo (maltodextrin) nor the LRa05 supplementation significantly altered the alpha or beta diversity of the gut microbiota, indicating no major shift in overall stability or composition. However, LRa05 supplementation specifically increased the abundance of Lacticaseibacillus species, suggesting potential colonization. Limitations include the small age range of participants, the use of only two time points, and the lack of additional health parameters like blood markers. The implications are that LRa05 appears to be tolerated and has colonization potential in healthy individuals, but its effects on the broader microbiota ecosystem and host health require further investigation.
