As suspected, Activia's bullshit.
[quote]In a randomized controlled trial, the probiotic Bifidobacterium animalis subsp. lactis – used in many probiotic products, including Dannon's Activia yogurts – did nothing to improve bowel health in people with constipation, according to data from a randomized triple-blind placebo-controlled clinical trial published Wednesday in JAMA Network Open.
[quote]The study adds to a mixed and mostly unconvincing body of scientific literature on the bowel benefits of the bacterium, substrains of which are sometimes sold with faux scientific-sounding names in products. Dannon, for instance, previously marketed its substrain as "Bifidus regularis."
