About Culturelle
Culturelle is a probiotic supplement brand built around a single, extensively researched organism: Lactobacillus rhamnosus GG (LGG), first isolated in 1983 and the most clinically studied probiotic strain in existence, with more than 1,000 published trials covering digestive health, antibiotic recovery, and immune support. The brand entered the US market in the late 1990s and has since expanded from its original adult capsule into women's, kids', and multi-strain formulas, most still built on the same LGG strain.
Culturelle is manufactured by i-Health, Inc., a division of dsm-firmenich, the global science-based consumer health and nutrition company. That ownership brings established manufacturing and quality infrastructure to a brand whose core evidence base, the LGG clinical record, is older and larger than almost any other probiotic ingredient sold in the US.
