Culturelle Daily Probiotic

8.0 / 10 · From ~$25 (30 capsules)

8.0

Probiotics are the supplement aisle's wild west, and Culturelle stands out for an old-fashioned reason: it uses one of the most-studied strains (Lactobacillus rhamnosus GG) at a disclosed dose, rather than a mystery blend with a sci-fi name. Evidence supports specific, modest uses - not gut transformation. Graded for honesty in a category short on it.

Why we rate it

Single well-researched strain (LGG) with decades of study behind it
Disclosed strain and CFU count - rare transparency for this aisle
Shelf-stable; no refrigeration logistics

Keep in mind

Probiotic benefits are strain- and situation-specific - broad 'gut health' claims oversell
