I always heard that probiotics were beneficial for gut health. Why are you against using them?

I disagree with the many “health experts” who recommend probiotics for children and adults to improve their gut health. While the concept of simply adding in some “good bacteria” is alluring, the formal medical science regarding gut health does not strongly support the use of probiotics. They may dampen some intestinal symptoms but do not resolve the bacterial overgrowth enough to lower inflammation and improve neurological recovery.
