The particle size in MetaCurcumin uses nanoparticles of curcumin. In addition, the nano-particles are encased in micelles. This alone has shown up to a 277x (a 277 fold) absorption when compared to standard curcumin. To that outstanding formulation, we have also added Sabinsa C3 reduct (Tetrahydro Curcumin, the white curcumin) to provide you with both the Micelle nano-curcumin and the white curcumin which has better activity than standard curcumin. Our formulation is quite unique and world-class. As far as we understand it. Theracumin provides a 27x (a 27-fold) absorption. MetaCurcumin with its nano-micelle formulation, high absorption (up to 277x), and two types of curcumin should allow you to make an easy choice between the products.
