Possibly Effective For<\/span><\/h3>\n

1) H. pylori<\/em><\/h4>\n

L. johnsonii<\/em> was inversely associated with H. pylori<\/em> colonization in 621 children<\/strong> (R<\/a>, R<\/a>) and in 12 asymptomatic volunteers (R<\/a>).<\/p>\n

Fermented milk containing L. johnsonii <\/em>co-administered with antibiotics was shown to have a favorable effect on H. pylori<\/em> gastritis in 50 volunteers (R<\/a>).<\/p>\n

During the early infection stages, administration of L. johnsonii<\/em> attenuated H. pylori<\/em>-induced gastritis in mice (R<\/a>).<\/p>\n

Both live and heat-killed L. johnsonii<\/em> inhibited the growth of H. pylori<\/em> in mice, where they also suppress gastric acid secretion (R<\/a>).<\/p>\n

Insufficient Evidence For<\/span><\/h3>\n

The following purported benefits are only supported by limited, low-quality clinical studies. There is insufficient evidence to support the use of L. johnsonii<\/em> probiotics for any of the below-listed uses.

Fermented milk with L. johnsonii<\/em> increased total Bifidobacteria and Lactobacilli and decreased lecithinase-positive Clostridium in 22 women (R<\/a>).<\/p>\n

L. johnsonii <\/em>intake increased the populations of C. histolyticum<\/em>, Lactobacilli, and Bifidobacteria, and decreased those of F. prausnitzii<\/em> in 8 volunteers (R<\/a>).<\/p>\n

3) Immunity<\/h4>\n

Fermented milk containing L. johnsonii<\/em> reduced the rate of infections in 24 elderly, hospitalized patients (R<\/a>).<\/p>\n

L. johnsonii <\/em>helps recover nutritional status and systemic immune responses in aged mice (R<\/a>).<\/p>\n

L. johnsonii<\/em> inhibits the growth of Helicobacter pylori<\/em><\/a>, Escherichia coli<\/em>, Salmonella<\/em> Typhimurium, and Clostridium difficile<\/em> in laboratory experiments (R<\/a>).<\/p>\n
