How to read a strain name
A strain name has three parts. Lactobacillus is the genus, rhamnosus the species, and GG the strain: one particular line of that species, kept and named so that it can be identified again. Two bottles can both say "Lactobacillus rhamnosus" and hold different strains. The code is what tells them apart.
Lactobacillus rhamnosus GG is the only strain printed on all six of our labels. The women's formulas share Lactobacillus reuteri RC-14 and Lactobacillus rhamnosus GR-1, and the 3-in-1 labels carry many strains with PB codes that appear on more than one of them.
A ® or ™ after a code means the strain name is a trademark of the company that owns it. Each of our labels names the owner, for example International Flavors & Fragrances or Chr. Hansen.
Effects found for one strain do not carry over to another strain, even of the same species: what each strain does is studied strain by strain. We name the strains so that you can look each one up.
