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 Wednesday in JAMA Network Open.
The tip off for me was “acid is meant to kill anything, whether it’s a pathogen or beneficial probiotic. Yogurt’s probiotics shouldn’t survive” followed by “took a double capsule probiotic designed to survive the stomach intact and open in the small intestine.”
Which is it, does the stomach acid kill everything or is there a pill that can survive that only to dissolve in your intestines?
There are special capsules designed to survive stomach acid, but there are plenty of studies showing they’re not necessary in most/many cases.
Then I suppose stomach acid doesn’t kill everything.
