Lactobacillus Gasseri

L. Gasseri is one of the species in BIFIDO|MAXIMUS, a Histamine-Free and D-Lactate Free Probiotic [20 Billion CFU of L. gasseri] which attempts to address two subsets of CFS patients. It is also available as a single species from Swanson [3 Billion CFU]. Neither indicated the strain(s).

“In humans, L. gasseri elicits various health benefits through its antimicrobial activity, bacteriocin production, and immunomodulation of the innate and adaptive systems. The genomic and empirical evidence supporting use of L. gasseri in probiotic applications is substantiated by clinical trial data displaying maintenance of vaginal homeostasis, mitigation of Helicobacter pylori infection, and amelioration of diarrhea.” [2013]

Role in Pregnancy and New Borns

It appears to be one of the species that appears to be transfer to new borns and dominate the vagina during pregnancy. “L. crispatus, L. gasseri and/or L. jensenii were present…  but as their estrogen levels rose, their flora composition altered, to become dominated by one of the three species most common in a normal, healthy vagina.”[2008]

Bottom Line

This lactibacillus species is definitely one that should be considered in the rotation of probiotics. Speculation: because of its involvement in female reproduction, females may be far more sensitive to it’s reduction than males, thus accounting for the difference of incidence between man and women.
