A randomized, double-blind, dose-ranging, pilot trial of piperine with resveratrol on the effects on serum levels of resveratrol.

ABSTRACT: Resveratrol (3,4,5-trihydroxystilbene) is a naturally occurring phytoalexin with purported health-promoting effects, but with limited oral bioavailability. Our prior murine modeling research observed enhanced resveratrol bioavailability with piperine co-administration. In this study, single-dose pharmacokinetics of resveratrol with or without piperine and the associated toxicities were studied on a cohort of healthy volunteers. We performed a double-blind, randomized, three-arm pilot study. Participants were randomized to receive a single dose of resveratrol 2.5 g, with piperine in 0 mg, 5 mg, or 25 mg dose. An improved liquid chromatography/mass spectrometry assay was used to determine serum levels of resveratrol and resveratrol-glucuronide. Baseline through 24 h post-study drug serum ana
