Overview: The Gastric Barrier Reality<\/h2>\n<p>The consumer nutraceutical market extensively markets colony-forming units (CFU) counts as the primary index of product potency. However, pharmacodynamic analysis reveals that raw, unprotected vegetative bacterial cells exhibit rapid destruction when exposed to human gastric fluid (pH 1.2 to 2.0) and conjugated biliary salts in the proximal duodenum.<\/p>\n<h2>2.
