Lactobacillus Brevis – IBS, Oral & Cognition Studies

I continue my research into different probiotic strains with this new Lactobacillus Brevis guide.

I spent hours trying read through everything and see what the science has to say about this strain.

Lactobacillus Brevis Benefits

Compared to some other lactobacillus strains like Helveticus and Salivarius there isn't nearly as many studies for this strain. 

There could potentially be a lot more benefits with this strain but they currently have not been studied. I did manage to find two good studies on L. Brevis so let me share them with you now.

Cognitive Function

L. Brevis Mouse Cognition Study.

It's not unheard of for consumers to report cognitive results when taking probiotic supplements. One study fed mice a Lactobacillus Brevis SBC8803 strain and the results showed an improvement in social recognition and other things critical to the survival of a mice. This is what that studies conclusion said word for word.

"Mice fed a heat-killed SBC8803 diet showed an improvement of hippocampus-dependent social recognition and contextual fear memories and enhanced adult hippocampal neurogenesis by increasing the survival, but not proliferation, of newborn neurons."

The mice were fed the SBC8803 Lactobacillus Brevis strain for 4 weeks and they wasn't any cognition related studies carried out humans that I could find. (1)

Oral Health

Plenty of studies have been funded looking at the benefits on oral health. Perhaps dental companies see the potential to create new products since dental health is a such a big business. This study mentioned anti-inflammatory effects and potential uses for periodontal disease which is also known as gum disease. 

This was the conclusion for the oral study:

"Our results suggest that the anti-inflammatory effects of L. brevis could be attributed to the presence of AD which prevented nitric oxide generation. Our findings give further insights into the knowledge of the molecular basis of periodontitis and have a potential clinical significance, giving the experimental ground for a new innovative, simple and efficacious therapeutical approach of periodontal disease."

IBS & Constipation

This study was interesting because it specifically mentioned that "no significant difference in IBS symptoms was noted". It then however went on to mention abdominal pain was reduced and "frequencies of watery and mushy feces were significantly lower". The Lactobacillus brevis KB290 strain was used in this study with 35 participants. (3)

This other study carried out on 32 Japanese women with a tendency for constipation mentioned that after taking the strain, there was a "A significant increase in defecation". These studies hint that there could be benefits if un regular bowel movements are a symptom of your IBS then this L. Brevis strain may help. (4)

Lactobacillus Brevis Foods

Lactobacillus bacteria are said to be found in fermented foods like Kimchi, Sauerkraut, Yogurt. You may also be able to find this strain particular strain Pickles if it's pickled with salt and potentially Sourdough bread which is a good option if you are lactose intolerant.

Final Thoughts

It will be interesting to see if any more studies on Lactobacillus Brevis show up in the future. If you find any that I missed please mention them in the comment section.

I must admit that I feel great after taking Probiotic Supplements containing this strain. Taking a multi strain probiotic supplement may be the smartest thing to do.

As always, nothing in this guide is medical advice. I am not a doctor. You should always contact a medical professional and not use Lactobacillus Brevis in place of any medical prescriptions.
