Effect of the intake of resveratrol, resveratrol phosphate, and catechin-rich grape seed extract on markers of oxidative stress and gene expression in adult obese subjects.

Background: The preventive effect of resveratrol (RES) on the development of human diseases has been verified by numerous epidemiological studies. Resveratrol triphosphate (RTP) is a stable derivative of RES in which phosphate groups protect the phenolic groups.

Aims: This study compared the effect of RTP on biochemical and molecular markers of oxidative stress to equimolar doses (0.
