Our Verdict
The best value in probiotics. Culturelle's hero strain Lactobacillus rhamnosus GG is the single most studied probiotic strain in human history — 250+ published clinical trials, with strong evidence for preventing antibiotic-associated diarrhea (meta-analysis: 22.4% to 12.3% risk reduction). You won't get the 24-strain complexity of Seed, but you'll get one strain that actually has evidence, at a quarter of the price (~$0.65/day).

About Culturelle
Culturelle is the 'eat the vegetables, skip the influencer' answer. The LGG strain has been in commercial use since 1990 and is hands-down the most-studied probiotic strain in the world. The Culturelle product itself hasn't been the subject of a finished-formula trial, but because it's essentially a monostrain delivery of LGG, the strain-level evidence transfers cleanly. Owned by Kenvue (formerly J&J Consumer Health).
