A multifunctional, curcumin-based composition with improved stability, solubility, and bioavailability.

Abstract

A cyclocurcumin-based composition consisting of: a cyclocurcumin component present at 20 to 40 wt% of the total composition; a curcuminoid component present at 30 to 50 wt%, comprising 20 to 30 wt% curcumin, 5 to 10 wt% demethoxycurcumin, and 3 to 8 wt% bisdemethoxycurcumin; a solubilizer component present at 5 to 15 wt%, comprising polysorbate at 3 to 8 wt% and lecithin at 3 to 7 wt%; a complexing component present at 5 to 12 wt%, comprising cyclodextrin inclusion complexes; and a nanoparticulate component present at 3 to 10 wt%, comprising cyclocurcumin particles with a particle size in the range of 50 nm to 200 nm. consists of a polymer stabilizing component, which is present in an amount of 4 to 10 wt.-% is present and comprises polyvinylpyrrolidone or polyethylene glycol, a phospholipid complex component present in an amount of 3 to 8 wt% and consisting of phosphatidylcholine complexes, and an encapsulation component present in an amount of 2 to 6 wt% and containing maltodextrin or gum arabic, the composition being configured to ensure improved solubility, stability and bioavailability.
