Buying Guide
Strain Diversity and Quality
A probiotic’s effectiveness hinges on the variety and quality of its bacterial strains. Multiple strains support different aspects of digestive and immune health, from breaking down food to maintaining a healthy gut lining. Both Renew Life and NOW offer blends with clinically validated strains, but their approaches differ. NOW Probiotic 10 features 10 strains known to naturally colonize the GI tract, while Renew Life Ultimate Flora includes 12 diverse strains, including B. lactis Bl-04 for respiratory support and L. rhamnosus GG for gut and immune health.

Potency and CFU Count
Colony-forming units (CFUs) indicate the number of live microorganisms per serving. Higher CFU counts are often associated with more potent support, but the ideal potency depends on your individual needs. NOW offers options at 25 billion and 100 billion CFUs, catering to both daily maintenance and restorative care.

Both brands prioritize quality, but your storage habits and travel needs may influence your choice.
