Microbiome

Probiotics

In plain language

Good bacteria supplements for gut health. Whether they actually help depends heavily on which exact strain is used.

Is it an approved medication?

No — not an approved medication

No - sold as a food supplement, not a medication

How strong is the evidence?

Depends entirely on the strain - some strains have solid evidence, most sold products don't specify well enough to know

The main thing to know

Don't assume all probiotic products are interchangeable - the specific strain matters a lot.

Mechanism

Live microorganisms that modulate gut microbiota composition, barrier function, and immune signaling; effects are strain-specific.

Potential benefits

  • Reduced antibiotic-associated diarrhea
  • Some benefit in IBS symptom relief

Regulatory status

Dietary supplement; specific strains may carry different regulatory/clinical claims
