High-potency, 4-strain, clinically-researched proprietary probiotic blend combined with Saccharomyces boulardii to support intestinal microbial balance and help lessen the occurrence of occasional diarrhea | PureBiOme Intensive offers 25 billion CFU per capsule of four clinically- researched probiotic strains, Lactobacillus acidophilus (NCIMB 30157), Lactobacillus acidophilus (NCIMB 30156), Bifidobacterium bifidum (NCIMB 30153) and Bifidobacterium lactis (NCIMB 30172), combined with 5 billion CFU Saccharomyces boulardii. The 4-strain blend is the focus of numerous clinical trials, showing support for healthy microflora, bowel function, and GI comfort. Saccharomyces boulardii is included as additional support for healthy bowel function. In a double-blind, controlled trial involving 151 individuals, S. boulardii supplementation lessened the occurrence of occasional diarrhea and supported overall bowel health. Research suggests that S. boulardii may stimulate enzyme secretions to support normal digestive functions and neutralize toxins for a healthy G.I. tract.
