Not all probiotics are equal. Choose strains with proof and support them with fiber and fermented foods.

Probiotics & Gut Health: What Actually Works

Strain matters. Dose matters. Consistency matters.

Best-Supported Uses

  • Antibiotic-associated diarrhea: S. boulardii, L. rhamnosus GG.
  • Infectious diarrhea: several Lactobacillus strains.
  • IBS relief (bloating/discomfort): targeted blends.
  • Immune support (URIs): modest reduction in frequency/duration.

How to Take

Empty stomach or ~30 min before meals; morning often works well. General: 1–10B CFU; specific issues may need 10–50B CFU.

Build the Terrain

Prebiotic fibers (inulin, FOS, GOS), fermented foods (yogurt, kefir, sauerkraut, kimchi), diverse diet, stress/sleep/exercise habits.

Choosing a Product

Look for full strain names, potency guaranteed through expiration, third-party testing, and minimal fillers.
