Red grapes or purple grapes?

[catlover]

Everything I've read on this board mentions red grapes b/c of the reservatrol. I've started eating red grapes and I feel it has helped with my MGD. When I've googled red grapes, it mentions they are good for DES. Yesterday I did a search for the best kind of grape juice, and I found a site (can't remember which) that said dark Concord grape juice is the best for this and has reservatrol. So, I want to start drinking grape juice in the morning and now I don't know if I should get red or dark purple grape juice. or does it matter? Anyone know?

Usually the darkest natural juice color indicates the highest level of reservatrol. If food coloring is added all bets are off. The color of the juice can come from the flesh or from the skins, just like with wine.
