Propionibacterium freudenreichii is widely used in the food industry, especially as a starter in the production of Swiss-type cheeses such as Emmental and Maasdam. These bacteria are essential for the development of a nutty and sweet flavor. They also produce CO2 responsible for the appearance of the holes typical of Swiss cheeses.
P. freudenreichii produces great-tasting cheese and important vitamins. This bacterium also beneficially modifies our microbiota and has beneficial effects on the GI tract.
In the food industry, P. freudenreichii is also used as a vitamin producer, certain strains having the ability to produce vitamins such as riboflavin and cobalamin (vitamin B12).
In addition to its traditional use, research has recently focused on health benefits related to P. freudenreichii [1]. It was shown that the consumption of this bacterium modulates the gut microbiota, which makes P. freudenreichii both a probiotic and a prebiotic.
Health Benefits of P. freudenreichii
P. freudenreichii probiotic supplements have not been approved by the FDA for medical use and generally lack solid clinical research. Regulations set manufacturing standards for them but don't guarantee that they're safe or effective. Speak with your doctor before supplementing.
Insufficient Evidence For
The following purported benefits are only supported by limited, low-quality clinical studies. There is insufficient evidence to support the use of P. freudenreichii Probiotics for any of the below-listed uses. Remember to speak with a doctor before taking P. freudenreichii probiotics and never use them in place of something your doctor recommends or prescribes.
) Gut Microbiota
Propionibacterium freudenreichii stimulated the growth of Bifidobacteria in the colon in healthy volunteers.
Bifidogenic growth stimulator (BGS) is a prebiotic preparation produced by P. freudenreichii that stimulates the growth of Bifidobacteria.
2) IBD
Propionibacterium freudenreichii improved the symptoms of mild to moderate ulcerative colitis in a human pilot study.
P. freudenreichii accelerated the healing in rats with colitis.
A component of P. freudenreichii improved survival rate and reduced damage in mice with colitis, by attenuating colonic inflammation through balancing intestinal bacterial flora and suppressing lymphocyte infiltration.
3) Constipation
Propionibacterium freudenreichii relieved constipation in 41 healthy young women.
Animal & Cell Research (Lacking Evidence)
No clinical evidence supports the use of P. freudenreichii probiotics for any of the conditions listed in this section. Below is a summary of the existing animal and cell-based research, which should guide further investigational efforts. However, the studies listed below should not be interpreted as supportive of any health benefit.
4) Inflammation
A component from P. freudenreichii suppresses the production of proinflammatory cytokines and attenuates colitis in mice.
5) Toxins
Propionibacterium freudenreichii binds cadmium and lead efficiently at low concentration ranges commonly observed in foods.
