Hafnia alvei 4597 Probiotic is available

A reader forwarded this to me with the following comment..

My mother is a health 58 years old women a little bit over weight she started to have after 2 weeks of use: headaches and feeling very fatigued so I think she has die-off, The interesting thing that happen she has swollen lymph nodes under her arm pits for about 25 plus years, the lumps started to regress, I cannot find the microbiome condition associated with this and this strain of probiotic she started to use.

This is available from France. Link here. International availability is unknown. “Hafnia alvei is a psychrotrophic bacterium, it originates in raw milk and continues to grow in cheeses such as Camembert.  abundant levels of Hafnia alvei can be found in raw milk cheese ” [Wikipedia]

 Corn starch; coating agent: hydroxypropylmethylcellulose; freeze-dried bacterial strain ( Hafnia alvei 4597 ); gelling agent: gellan gum; zinc (zinc bisglycinate, glycine, acidifier: citric acid, anti-caking agent: silicon dioxide [nano]); anti-caking agents: magnesium salts of fatty acids; chromium (picolinate).

  • “In conclusion, the present study showed that a daily provision of the H. alvei HA4597™ strain in genetically obese and hyperphagic ob/ob mice with HFD-exacerbated obesity decreased body weight gain, improved body composition, decreased food intake, and ameliorated several metabolic parameters, including plasma glucose and total cholesterol levels. “

  • “Finally, the low abundance of ClpB gene expressing Enterobacterales species found in the microbiota of obese subjects in the present in silico analysis may indicate insufficient anorexigenic signaling from the gut microbiota to the host, further providing the rationale for supplementation of commensal bacteria expressing the ClpB protein with an α-MSH-like motif. “

Bottom Line

There was no detail microbiome information cited in studies above. The mechanism of operation was increase production of a metabolite from this bacteria that alters the number of meals and result in weight loss.

The daily dosage is 50 million CFU ** / 100 billion cells, i.e. 5 x 10^7. Some (made in France) Camembert are reported to exceed this level in 1 gram (especially the surface).

It is available as a specialized cheese starter.
