Decreasing Prevotella genus

I did an earlier post on a member of this genus which was reported high in most CFS patients by Ian Lipkin et al 2017 study .  In this post we can add probiotics to the list of controlling substances instead of just antibiotics.

Bottom Line

  • No Lactobacillus salivarius
  • No Lactobacillus gasseri
  • No Lactobacillus casei
  • No Lactobacillus rhamnosus GG.
  • No Rosemary
