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.

Stomach acid is meant to kill anything, whether it’s a pathogen or beneficial probiotic. Yogurt’s probiotics shouldn’t survive the stomach if all is going well.

I had severe gut dysfunction due to multiple parasites and pathogens from spending a year in India. I had dysbiosis, IBS-C and SIBO all diagnosed, and for five years I developed a debilitating autoimmune condition that made eating nearly impossible without intense systemic inflammation, brain fog, body pain, etc.

In addition to multiple pill based probiotics I did literally every home fermentation project I could figure out; kraut, kimchi, yogurt, kefir, etc. None of them helped one bit. I eventually took a double capsule probiotic designed to survive the stomach intact and open in the small intestine and my symptoms were mostly resolved within a week.

I wish this was more common knowledge. We are just starting to understand how crucial gut health is to overall health, including mental health, and basically everyone gets their gut biome carpet bombed with antibiotics on the regular.

Stomach acid doesn’t kill all bacteria or pathogens. That’s how I got whipworm, roundworm, E. coli and giardia from food in India. Some bacteria may be more or less susceptible to the stomach environment. It looks like tests have shown some probiotics do tend to survive the stomach.
