Results suggest that black grape strengthens plasma AOP as does red wine. This result also support the hypothesis that the protective effect of red wine against cellular peroxidation reactions and atherogenesis mainly arises from its flavonoid constituents rather than alcoholic content.

It means that people may gain enhanced antioxidant defense against atherosclerosis by consuming black grape as well instead of drinking red wine if they really drinks for this aim.

Oxidative Stress - the objective of our research was to study parameters of the prooxidative-antioxidative balance in athletes supplied with Panace-Vid preparation consisting of black wine grape extract (Vitis vinifera).

An analysis of the results revealed that the supply of grape extract, in the form of Panace-Vid preparation, contributed to a significant increase in plasma antioxidative capacity and to an insignificant increase in superoxide dismutase, as well as a lower activity of glutathione peroxidase and reduced concentration of lipid peroxidation product levels.

Aim of this next study was to evaluate the potential protective effects of ad libitum black grape (Vitis labrusca) juice against liver oxidative damage in whole-body acute X-irradiated rats.

Ad libitum black grape juice intake is able to restore the liver primary antioxidant system against adverse effects due to whole-body acute X-irradiation in rats after 15 days post-irradiation. The results support using antioxidant supplements as a preventive tool against radiation-induced harm.

Heart Health - The aim of this study was to evaluate the potential positive effect of black grape juice (BGJ) on lipid peroxidation considering Total Body Irradiation (TBI) in Wistar rats. High concentration of metabolites from lipid peroxidation in heart, and high LDH level on serum were found only in gamma-irradiated group given placebo, mai
