Probiotic Broad Spectrum is a formulation designed to provide 10 billion live colony forming units (CFU) of eleven different strains of beneficial probiotics per caplet.

Probiotics are healthful and necessary bacteria found in the body and have been shown to promote healthy cytokine production in the colon and maintain healthy gastrointestinal barrier function, by supporting intestinal epithelial integrity. Studies have also shown that mixed probiotic supplementation helps maintain intestinal flora, support healthy yeast balance, and promote gastrointestinal comfort.

Clinical studies indicate that Lactobacilli and Bifidobacteria species supplementation supports healthy immune response and cytokine balance. Probiotics may enhance B cell, T cell and NK cell function, phagocytic capacity and activity, and healthy cytokine production.

Stomach acids can destroy all of the probiotic organisms before they reach the intestinal tract where they can do their good work. BIO-tract® tablets protect probiotics from gastric acid, ensuring that a significantly higher percentage of organisms reach the intestines alive.
