Mark Dain Ok leaving it in the fridge overnight was the trick! No more powdery flavour! The taste has gotten a bit bland though but that may be due to the fact I put less powder in. I know it's leaving it overnight as when I shook up this shaker yesterday, I poured a bit into a glass and it still tasted like powder. The next day it tastes like a smoothie. #Joylent

Eric Are these things completely vegetarian?
