Probiotics

Evidence: ★★★☆☆ · Status: OTC Supplement

💡 Did you know? You're roughly half 'not you' — your body carries about as many bacterial cells as human ones, most of them in your gut.

In plain English

Helpful bacteria that crowd out bad ones and feed your gut lining. The catch: benefits depend on the specific strain, so match strain to goal.

How it works

Live strains that competitively exclude pathogens, produce short-chain fatty acids (butyrate → colonocyte fuel, FFAR signalling), and modulate gut immunity. Effects are strain-specific, not generic.

Molecular target & official sources
