Probiotics: why strain identity matters more than CFU count

The CFU illusion

Probiotic marketing fixates on Colony Forming Units — but a 100 billion CFU product of a poorly characterized strain may do less than a 10 billion CFU product of a well-studied one.

Strains, not species

Lactobacillus rhamnosus GG is one of the most validated strains in the world. Bifidobacterium longum BB536 has decades of safety and efficacy data. These exact identifiers — letter-number combos — are what trial data attaches to.

ZYVORA Daily Probiotic contains 15 named, identifier-validated strains at clinically used doses, delay-release encapsulated to survive stomach acid.
