Nothing is more magical than a child being born. But something equally spectacular and significant happens in the time before a newborn baby completes its journey out of the birthing canal.

This spectacular event – one that cannot be seen – is where human microbial organisms are introduced to humans: in other words, when a newborn's microbiome (the collection of resident microorganisms living on and inside the human body) is formed.

It is the microbiome which provides the blueprint of future health for each brand-new human life.
