Be aware that not all probiotic products live up to their label claims, according to the supplement testing company ConsumerLab.com (CL). Probiotics are “friendly” bacteria that are promoted for digestive and other health benefits, though research results have been inconsistent at best.
In any case, not all the organisms even survive by the time you consume them. In recent CL testing, five out of 19 supplements tested before their “best by” dates had only 16 to 56 percent the amount of live organisms claimed on the label. Some products carry a qualifier that the number of live organisms listed is “at time of manufacture”—but this doesn’t pass muster with the Food and Drug Administration (FDA), which requires that supplements meet their label claims throughout their entire shelf life.
