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.

This is misinformation.

I had SIBO

Not likely. https://humanmicrobiome.info/sibo/

You’re getting your information from poor quality sources.

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.

Almost certainly placebo or random luck. There are a plethora of probiotic and FMT studies that show it can have significant impacts when you take it directly orally:

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.

Agree. I’ve done FMT from 15+ donors and haven’t yet reversed the damage from antibiotics. When I would share studies about this on reddit I would get viciously attacked by people who seemed addicted to antibiotics.
