The answer is:  With food.  Always.  Why you ask?

Simply put - the acidity level of your stomach when it is empty is somewhere in the range of 2.5 pH - somewhat akin to battery acid.  There isn’t much that can survive in that climate which is part of the reason why your stomach is considered part of your first line of defense against foreign pathogens.  So.  When you have some food and then probiotics, either during or immediately after, the food buffers the pH getting it to a somewhat friendlier range of 4.5 or so hence giving your new guests a fighting chance to make it a bit further down your GI tract to do their thing.  

This past weekend I attended a full day course on the human microbiome and its relationship to health and disease.  I won’t bore you with the details but over the next while will share with you some of the key learnings I walked away with.  The presenter was Dr Nigel Plummer a researcher who has devoted much of his career to developing specific strains of probiotics and doing clinical studies to prove their efficacy - his company supplies said strains to Genestra one of the larger players in consumer probiotics.
