Should I Take Resveratrol And Grape Seed Extract For Health

Should I take resveratrol and grape seed extract for health benefits. I have only been taking resveratrol? I have been taking 100mg of Resvida (brand - StayWell) daily. I was going to start taking grape seed extract, as I have seen they have different benefits. I was thinking I would continue to take 100mg of Resvida/day and then also take 150-300mg of grape seed extract/day.... What do you think?

I did not realize there was a cost involve. The website should be up front about this cost!!! I am also not sure if this is real time or my question is in a queque.
