20 billion CFU with 10 diverse strains covering both Lactobacillus and Bifidobacterium genera. The strain diversity is good and 20B CFU is adequate for daily maintenance. L. acidophilus as the leading strain is well-studied. No information on guaranteed CFU at expiration (shelf stability). For a store-brand probiotic, this provides solid broad-spectrum gut support at good value.
The set is generated, never written by the brand.
Up & Up Probiotic 10 Strains 20 Billion CFU: the formulation holds up. Lead: Probiotic Blend at 20 Billion CFU. 20 billion CFU with 10 diverse strains covering both Lactobacillus and Bifidobacterium genera. Clinical dose on the primary, and the panel holds together.
Target's middle-ground probiotic: 10 strains at 20B CFU. More diversity than Culturelle, less firepower than Physician's Choice 60B. For daily gut maintenance from the Target aisle, this does the job.
