Propionibacterium freudenreichii – Another Probiotic of Interest

Many thanks to Espen Samuelsen for finding another commercially available probiotic that I was not aware of: Propionibacterium freudenreichii 

It is available as NutriCology Allergy Research‘s Securil Propio-Fidus.

No, it’s not a psychoanalysis probiotic (the “Freud” in it’s name), it is actually used in making  Emmental cheese!

So what do we know about it (apart from being used to make one of my favorite cheeses!)

Looking at colitis

Bottom line: If passes my baseline criteria for use with CFS — it is effective for IBS.  “I approve this probiotic!”


Update – thanks to AM for doing further research and forwarding it.

  • “During cheese production, Propionibacterium freudenreichii ferments lactate to form acetate, propionate and carbon dioxide. The Propionate is a salt of propionic acid. Propionic acid is an organic, carboxylic acid, and is strongly anti-fungal, and supplementation with P. freudenreichii can boost the localised Propionate levels in the GI tract and help to eliminate Candida albicans and other yeasts and moulds. The Propionic acid molecule is shown below.“A bacterium used in the production of Emmental.” Genoscope. 16 Jan. 2008
  • “The five common strains of Bifidobacter include B. infantis, B. adolescentis, B. bifidum, B. longum, and B. breve. [P. freudenreichii]…provides the food that allows growth of all Bifidobacteria, so your body can maintain its own unique, health-promoting combination of the different stains. The Bifidobacteria levels remain high in your gut only while they have adequate food and stimulation to grow. ‘ [1987]
