Comparative oral bioavailability advantage from curcumin formulations.

The aim of the present study was to study the oral bioavailability of seven different formulations of curcumin (CRM). CRM formulations viz. aqueous suspension, micronized suspension, nanosuspension, amorphous solid dispersion, hydroxypropyl-β-cyclodextrin (HP-β-CD) inclusion complex, combination with piperine, and spray-dried CRM-milk composite were compared for oral bioavailability in male Sprague-Dawley rats at a CRM dose of 250 mg/kg body weight using a validated high-performance liquid chromatography method.
