Probiotics

Live cultures for gut and immune health — strain-specific and individual, so results vary a lot.

EVIDENCE
Moderate
TYPICAL DOSE
Follow the product; the strain matters more than the raw CFU count
TIMING
Consistently; some prefer with or just before a meal.
WHAT IT IS

Live beneficial bacteria supplied to support the gut microbiome, sold as capsules, powders or in fermented foods.

WHY (OR WHY NOT)

Evidence is decent for specific strains and specific problems (antibiotic-related upset, some digestive issues) and for general immune support, but it's very strain-dependent — a benefit for one strain doesn't transfer to another. Fermented foods are a good, cheaper route.

CAUTIONS
  • !Effects are individual — give a given product several weeks and judge honestly.
  • !Yogurt, kefir, kimchi and other fermented foods deliver similar benefits.

Note:General information, not medical advice. Supplements interact with medications and conditions — check with your doctor before starting anything, especially if you're pregnant, nursing or managing a health condition.
