Several earlier studies have shown that Bifidobacterium infantis (B.infantis) might make a significant difference in cases of Irritable Bowl Syndrome (IBS).
Now a meta-study has confirmed this particularly noting that B.infantis, when included as part of a multi-strain probiotic.
IBS is a product of an out of balance microbiome and no one factor has been isolated as a cause. Excess yeasts, holes in the gut wall, Clostridium dificile and possibly other pathogens may well play a part.
In 2015, a meta-study(1) showed that probiotics could significantly reduce pain and symptom severity scores. 15 studies were included with a total of 1793 patients.
In a 2017 study (2), researchers from Illinois Medical Center and the University of Louisville Health of Louisville Health Sciences Center were concerned that although benefits were being shown for one particular probiotic strain, (namely Bifidobacterium infantis 35624), results had been somewhat inconsistent. The researchers therefore imposed some stringent standards for their meta-review.
In placebo controlled clinical trials up to December 2016, the researchers found that 5 studies were acceptable, three testing B.infantis on its own, two as part of a multi-strain probiotic. The results were very clear:
- Where B.infantis was used alone there was little impact on bloating/distention, bowel habit or abdominal pain
- Where a multi-strain probiotic was used that included B.infantis significant benefits occurred. When the two studies were added to four more similar studies, the benefits of reduced bloating/distention, bowel habit and abdominal pain remained significant. When Chris Woollams designed and launched his own probiotic in 2017 he deliberately used several gut healing strains including Bifidobacterium infantis; please refer to Natural Selection.
HEAL YOUR GUT – HEAL YOUR BODY First published in 2014 this book written by Oxford University graduate Chris Woollams provides a clear and precise insight into looking after your ‘gut’; your engine.
