Pros and cons

24/7 Digestive Support Probiotic

  • A single, named strain studied in IBS trials since the mid-2000s
  • The label openly states CFU at manufacture and at the best-by date
  • One capsule a day, with no refrigeration needed
  • Sold at most U.S. pharmacies and big-box stores
  • Guarantees only 10 million CFU at the best-by date, 100 times less than at manufacture
  • Mixed trial results, including no significant change in symptom severity in a large non-IBS trial
  • About 96 cents a capsule, expensive for a single strain
  • No third-party certification, and the capsule contains titanium dioxide

Digestive Daily Probiotic Capsules

  • One extensively researched strain (LGG) at 10 billion CFUs
  • Potency guaranteed through the date on the box, with blister-sealed capsules
  • About 58–60 cents a day for the 30-count box
  • One small capsule a day, with no dairy-derived ingredients, gluten or soy
  • LGG's evidence in adults is weaker than in children
  • No NSF, USP or other third-party certification
  • The capsule contains titanium dioxide as a colorant
  • Some users report diarrhea or gas in the first weeks

Our verdicts

24/7 Digestive Support Probiotic

Align's strain has real research behind it, but the results are mixed, and the label guarantees only 10 million CFU by the best-by date, below the dose that worked in its key IBS trial. It's easy to take and easy to find, yet the price is hard to justify against cheaper, better-dosed options. It's worth a four-week trial if your clinician suggested it; otherwise, we'd look elsewhere first.

Digestive Daily Probiotic Capsules

Culturelle Digestive Daily is our budget pick: one extensively researched strain at 10 billion CFUs, with potency guaranteed to expiration, for well under a dollar a day. Research on LGG is strongest in children and around antibiotic use, so adults looking mainly for bloating relief should keep expectations modest. It's a sensible, low-risk first probiotic to try.
