Auspicious' revolutionary UltruSil contains stabilized Orthosilicic Acid, the only form of silicon absorbed directly through the stomach wall and the gastrointestinal tract into the bloodstream. Orthosilicic Acid is the most important metabolite for organic silicon compounds. What is the features of UltruSil ? High Potency - Introducing UltruSil into the stomach increases the Orthosilicic Acid concentration by a factor of 20,000. Normally, the solution of Orthosilicic Acid is limited: Orthosilicic Acid is present in water and body fluids at an average concentration of 1 mcg of net elemental silicon per ml (one part per million or 0.0001%). However, due to its unique stabilization formula, UltruSil contains 20,000-fold more silicon per ml, i.e., 2% silicon Orthosilicic Acid. Maximum Absorption - UltruSil is a high absorption silicon product. UltruSil contains a high concentration of biologically active silicon--stabilized Orthosilicic Acid. Orthosilicic Acid is the only silicon compound that absorbs directly through the stomach wall and the gastro-intestinal tract.
