Mixing Shakes???
VSG on 06/26/12
Some shake powders make more foam than others, but you likely don't have many choices right now. What I found helped with the foamier ones was mixing them up before bed for the next day. The foam subsides in the fridge overnight.

I have a Vitamix, which can blend a tire if you need it to. I found the same issue with foaming. I mix my fluids and ice first and the blend them to the proper consistency. Then I put in my protein powder and slowly blend until mixed in. When I want to make protein ice cream, it helps to have some air whipped into the mix.
