If you're looking for broad-spectrum gut support, this packs 20 strains and 65 billion CFU into a single capsule. The strain list goes well beyond the standard Lactobacillus/Bifidobacterium pairing — you're also getting **L. rhamnosus GG** (one of the most researched probiotic strains in existence), **L. reuteri**, **L. gasseri**, and **S. thermophilus**, giving you unusually broad coverage across digestive, immune, and metabolic pathways.

The formula includes fructooligosaccharides (FOS) as a prebiotic, which feeds the beneficial bacteria and may help them colonize more effectively. Each capsule is individually double-foil blister sealed, and the product is shelf-stable without refrigeration — practical if you travel frequently.

With 30 capsules per container, this is only a one-month supply. What this means for you: the per-strain CFU breakdown isn't disclosed, so across 20 strains at 65 billion total, some will inevitably be present at low levels. Still, the strain diversity here is notably higher than most probiotic products on the market.
