Gut health is a topic we have explored quite relentlessly in our blog.

From 10 Kitchen Habits That Are Damaging Your Gut to the links between gut health and B12 status, via 6 Signs of Poor Gut Health and 3 Key Factors You Must Consider to Improve Diversity, we have produced thousands of words, referenced countless studies and communicated the myriad benefits of a rich microbiome to anyone who’ll listen for the last decade.

During the same time period, we’ve witnessed the probiotic industry explode like a hydrogen bomb, with more manufacturers releasing patented probiotic formulas that they claim will solve everything from hay fever to psoriasis.

There have also been many books published on the topic, and it’s fair to say that the importance of gut health is now well and truly established in the field of preventive medicine and clinical nutrition.

But a question that continues to rear its head is this: are multi-strain probiotics preferable to single-strain? And if so, why? It’s a query we intend to answer, once and for all, in today’s blog.
