PCA-Rx is different from chelation agents. It works on the principle of clathration. Its contingent of specifically sequenced peptides form a lattice or inclusion complex. Multiple receptor sites attach to a toxic molecule with irreversible bonds, literally wrapping around the toxic substance to prevent additional reactions with tissues or organs as it is eliminated from the body. PCA-Rx line of products utilize "Systemic Micro-Activated Response TechnologyTM" or SMART nutrients technology. According To The Physician's Desk Reference, the maximum absorption of nutrients we can expect from oral supplementation with pills and tablets is 15% to 25%. Finding solutions to overcome this problem with absorption has been a primary focus of research and development at Maxam Laboratories for years. As you know, many incredible medicinal supplements have been discovered, but the problem lies in getting them into the cells to do their healing work. Fortunately, SMART Nutrients has developed and incorporated a multidimensional technology designed to overcome every aspect of poor absorption. To Fully Utilize A Nutrient: * Uptake must be complete - all of the nutrients must be completely absorbed into the blood. * Supplements must be in a natural, ionic form so that the liver recognizes the nutrient as natural and does not trap it out as a 'foreign' substance, to be denatured and eliminated. * All actives must be completely preserved using chemical free, Cryogenic Extraction Technology. * All actives must be highly concentrated and 100% pure - then very small amounts will be highly effective. * Carrier must simulate the body's natural fluids - i.e. be in true colloidal form. * Nutrients must be cell site specific - enzymatically bound into Micro Activated BiospheresTM with the precise enzymes that will only unlock the nutrient payload only at the target cell sites. * Electrokinetic absorption - Supplements must contain the correct ionic charge so that absorption from the bloodstream into the cell will occur solely by electrokinesis. * The source of raw materials must be Live - Organic or Wild. SMART Nutrients effectively address every aspect of supplementation and absorption in the above list.
