L. rhamnosus GG Probiotic Oil Drops
Lacticaseibacillus rhamnosus GG · 100 million CFU in 5 drops · one of the world’s most-researched probiotic strains
Overview
Most probiotics rely on research done on their species. Strain GG has its own record. First isolated from a healthy human gut in 1983 by Sherwood Gorbach and Barry Goldin (the “G” and “G” in its name), it has been used in foods and supplements worldwide for three decades.
Our L. rhamnosus GG oil drops put this strain into a taste-neutral oil drop. Five drops a day deliver 100 million live CFU, meeting FSSAI’s benchmark for a source of probiotic.

Is every “GG” the same GG?
Bacteria can drift. In 2013, researchers found some “GG” products whose bacteria had lost their pili genes. Our GG comes from frozen seed lots, with a 16S check on every batch and whole-genome comparison. Its genome matches the GG reference, pili genes included.
