I'm looking for a multi-vitamin powder... thing :)

Hey all,
I could never do the whole "swallow massive pill" so I'm now looking for a multi-vitamin that's in powder format that I could get away with only taking twice or three times a week. My plan is to throw it into the blender bottle with the current post-workout whey + milk/water mix and chug it down after I shake it a bit. I say twice, as that's usually the amount of times i goto the gym, but three in case I get weird ideas, and goto the gym on the weekend (it has happened sometimes).

TL:DR; lazy ass foo is looking for a all-in-one powder to use after the gym with the whey.
