Best Greens powder?

[Sarain]

My juicer is old and cheap, and just won't juice leafy greens even when wraped around carrots..So I want to go buy a greens powerder today and am wondering what the best powerder is?? I'm thinking maybe spirulina or wheat grass? Are there other green powders? How much should I add to my juices while I'm on a 10 day cleanse?

Thanks!

Alissa's Green Food Powder. I use a heaping tablespoon daily in my green smoothie. :D
