What do probiotic bacteria do?


You can buy many different probiotics but it is important to remember that they are not all created equally. First of all, you must choose a product that contains optimum numbers of the right species of bacteria.

Lactococcus lactis, proven to fight off the harmful salmonella species of bacteria and also have an anti-inflammatory effect in the bowel.

Bifidobacterium longum, which is one of the earliest to colonise our bowels when we are infants. It is considered a staple species in a healthy microbiome.

Bifidobacterium breve is another healthy microbiome staple and plays a key role in protecting our bowel from being colonised by harmful bacteria. 

  • https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2949774/ – IBS

Lactobacillus acidophilus are a species of bacteria that produce chemicals that kill off dangerous bacteria when they ferment our food. These bacteria are also helpful for digestion and treating diarrhoea.

  • https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4266241/ – treatment of colitis 

Lactobacillus plantarum is an important species as it helps to suppress the growth of bacteria that produce gas and therefore cause unpleasant symptoms such as wind and bloating. It is also showing a lot of promise as a treatment for depression. 

  • https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3601973/ – intestinal permeability and depression

Lactobacillus rhamnosus is shown to be important for the prevention and treatment of diarrhoea through its ability to kill off harmful bacteria.

  • https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5745464/ – antibiotic-associated diarrhoea 

Streptococcus thermophilus has been shown to be effective in reducing the risk of diarrhoea that is caused by antibiotics.

In combination, these species are shown to alleviate the symptoms of IBS, prevent diarrhoea associated with travelling and antibiotic use and calm inflammation in the gut.
