Lactobacillus gasseri strain SBT2055 (LG2055) showed its abilities to reduce stomach fat (abdominal adiposity) even at doses as low as the order of 10(8) cfu/d. Constant consumption might be needed to maintain the effect.
Lactobacillus gasseri BNR17 isolated from human breast milk can inhibit obesity and diabetic activities in the human body, but weight reduction after taking this probiotic is very small.
Lactobacillus gasseri OLL2716 proved effective in both suppressing H. pylori colonization of the stomach and reducing gastric mucosal inflammation. L. gasseri OLL2716 strain contained in a yogurt drink can colonize the gastric mucus layer in infected patients. It does so by coccoid conversion of H. pylori (manifestation of their death) due to dl-lactic acid.
