There are 4 core technologies that help the absorption of Turmeric curcumin suppements into the body.  Most of these technologes were invented more than a decade ago using standardized approaches to improving the absorption of curcumin into the body. The Issue with Curcumin is that its an insoluble crystal.  It's like swallowing quartz crystals and expecting the silica from the quartz to absorb into your body.  Most of the technologies being used rely on trying to improve the rate of disolution of Curcumin from its native crystal.
Technology 1 - Black Pepper Extract with Turmeric Curcumin 95.  Typically Your Lowest Price with the Most Hype.  Black Pepper Extract, does not improve Absorption but Inhibits Your Liver, Slowing down the rate at which your Liver degrades the little Curcumin that is Dissolved and Absorbed. We don't really want to inhibit our livers, most reports share that it takes 1-2 months to feel a difference.
Technology 2 - BCM95 is Curcumin Extract Slightly Dissolved in Turmeric Oil.  The idea is elegant but the benefits are mediocre.  Most people are reporting a response within  2 to 4 weeks.
Technology 3 - Theracurmin is a Nano-Particle technology that coats the nano particles to keep them from sticking together.  The Small size of the particles exponentially increases the surface area resulting in better dissolution and absoprtion. Technology 4 - Micel/Liposomal Phytosomal technologies typically puts solid nanoparticles of curcumin to into Liposomes or Micels.  These delivery spheres help the nano particles to adhere to the intestinal wall and aid in their absorption.  However mostly what is absorbed are the nano-particles.
Technology 5 - UltraCur LPS Technolgy is the Newest Technology Available - Using Molecular Curcumin bound to a Protein Scaffold.  What happens is as the Scaffold is Digested by the Body Molecular Curcumin is Released allowing Free Curcumin Molecules to Get into our Body and benefit out cells.
