So I run a probiotics site...and what that marketing claim means is that that precise strain of Lactobacillus Rhamnosus is the most researched.

There are many more studies on the species of probiotic Lactobacillus Rhamnosus as a whole...but for that exact "cousin" of the species, it is likely the most clinically researched probiotic.

There's a bit more info on it here: http://probiotics.org/lactobacillus-gg-benefits/
