Green Powders and Juice

Any suggestions on good ways for incorporating green powders into a juice fast? I drank it last night mixed with water, and this morning mixed with carrot/apple juice. The taste is still pretty dang bad! Any suggestions on which vegetable juices or fruit juices work well with the taste of the powder? someone suggested grapefruit and other citrus, but i haven't tried it yet!

Do most of you use green powders at all? the one i have is "Phyto Green."

Thanks for any suggestions!

I'm trying to do this on my juice fast as well. Personally I have been mixing it with just water and getting it down so as not to destroy my delicious juice :) Maybe some lemon would help? Ginger? Something strong like that. I recently started using perfect food. It's great stuff but the taste is icky... Let us know if you come up with a good solution!
