About Culturelle®

Did you know that 70% of your immune system is in your digestive tract? That's why it's important not to think of digestion and immunity as two separate issues. What happens in your core is crucial to your overall health.

Optimal health starts in the core - with improved digestion and a stronger immune system - and Culturelle, an all-natural dietary supplement containing the probiotic Lactobacillus GG, can be an important step achieving yours.

Culturelle is a pharmacist-recommended probiotic. Our success is in our science: Culturelle's Lactobacillus GG is one of the most effective strains of good bacteria (or probiotic) at balancing out the causes of gas, bloating and stomach upset. And with better digestion, your immune system is stronger and ready to fend off bad bacteria.

Every Culturelle package has a Certificate of Purity and Potency: Lactobacillus GG was discovered in 1985 at Tufts University in Boston, MA by Dr. Sherwood H. Gorbach and Dr. Barry R. Goldin. Considered to be the premier probiotic in the world, Lactobacillus GG has been the subject of more than 400 scientific studies. Not all probiotics are the same; to provide a beneficial effect, a probiotic must meet specified levels of purity and potency at time of use. The Gorbach Goldin Institute (GGI) has been established to assure that products meet these high standards. Only probiotics that carry the GGI seal have been certified as containing Lactobacillus GG that meets these high standards of purity and potency.
