Cardiotabs Curcumin is where advanced science meets a wonder of the natural world. Theracurmin®, the primary ingredient in Cardiotabs Curcumin, is a nanoparticle (extremely tiny pieces) formulation of curcumin that enables it to be absorbed into water. The result is a higher level of curcumin in the bloodstream, brain and joints (about 30 times greater than a comparable dose of conventional curcumin).
