Across 3 studies, 2 reported beneficial effects of Lactobacillus salivarius UCC118 on modulating gut microbiota, with effect sizes ranging from small to moderate. No studies reported harmful effects, and none of the findings were statistically significant. All studies were reviews, limiting the strength of the conclusions, and the most commonly mentioned population was pregnant women (in one study).
Caveats: All three studies are review articles, not original trials, so the evidence is indirect and may include overlapping references. No studies reported doses or sample sizes, and none provided statistical significance, limiting the ability to draw firm conclusions.
bacteriocin-producing probiotic lactic acid bacteria in the modulation of gut microbiota correcting dysbiosis
live probiotic bacteria present in some food products (which transit through the GIT) have been shown to interact with the host immune system and confer several health benefits
using dietary supplements, such as probiotics, prebiotics, and synbiotics to target the gut microbiota to regulate the disordered gut microbiota would become a potential method that benefits for preventing and treating GDM
