Reading the label beyond the headline

NIH advises attention to the full strain name, storage instructions and viable counts through the use-by date. A count measured only at manufacture does not account for organisms dying during storage. 1

CLA8013 was studied after heat treatment, so its positive result is not evidence that the bacteria must be alive or settle in the gut. It is also not a reason to substitute an unrelated live strain for the tested preparation. 2
