Our verdicts
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.

Synbiotic+
Synbiotic+ pairs two of the best-researched probiotic strains with a potency guarantee through expiration and top-tier testing transparency. The extras you pay for, the phage prebiotic and tributyrin, have limited human evidence, and the finished formula hasn't been tested in people. It's a solid premium pick if you value traceability; budget shoppers can get LGG alone for a fraction of the price.
