Multiple Strains, Multiple Benefits Ultimate Flora Men's Once Daily Probiotic 65 Billion CFU1 contains 31 different strains of beneficial probiotics from four different genera – – Bifidobacterium, Lactobacillus, Lactococcus, and Streptococcus. Other brands contain only Bifido or only Lacto. Because your gut naturally contains a variety of probiotic strains, a broader mix of B's and L's in your probiotic supplement may offer greater benefits.* Microbiome Optimal Balance* Bifidobacteria, naturally found in milk, kefir, sauerkraut, kimchi and other fermented foods, declines as we age. Bifidobacteria are abundant in the intestinal tract, offering key health benefits and aiding digestion of complex carbohydrates. Our focus on bifidobacteria, which is less common in supplements, provides balanced microbiome support compared to lactobacillus-dominant competitors. Ultimate Flora Men's Once Daily Probiotic 65 Billion CFU1 is specially formulated to contain Bifidobacteria to support a balanced microbiome.* Delayed-Release Vegan Capsule Technology Stomach acid can destroy probiotics. But Ultimate Flora delayed release vegan capsules ensure probiotics survive the harsh stomach environment and reach the intestines.* Unlike regular capsules (10-65 min release), Ultimate Flora Men's Once Daily Probiotic 65 Billion CFU1 delayed release vegan capsules release probiotics 75-120 minutes post-ingestion for targeted intestinal delivery. *These statements have not been evaluated by the Food and Drug Administration.
