Recently I found that the bacteria that produces/releases B12 was identified in 2003. There have been a half dozen articles confirming that this bacteria produces B12, as well as what encourages and discourages the amount produced.
This bacteria is part of a family that is known to be low in CFS patients… low population, low production seems obvious. The bacteria is Lactobacillus Reuteri. It is recognized as a seperate species in the Lactobacillus family. It is found in mother’s breast milk. It is the dominant Lactobacillus found in most species, so if the Lactobacillus population is low, L. Reuteri will be low.
There is a 2009 article that identifies what affects the production of B12 by this bacteria. The following are needed to a moderate degree (absence may result in a 20% reduction)
- alanine (Ala),
- aspartate (Asp),
- cysteine (Cys),
- glycine (Gly),
- lysine (Lys),
- proline (Pro)
However, isoleucine (Ile) appears to be essential. This amino acid is not produced by humans, but may be obtained from eggs, soy protein, seaweed, turkey, chicken, lamb, cheese, and fish. You can view a detailed list here.
- A Lactobacillus Reuteri and Lactobacillus Rhamnosus mixture is available
Lactobacillus Rhamnosus has some significant benefits (I will cover it in a later post).
