How much protein?
35 - 40g per serving is what I've heard from a couple of doctors in a single sitting.
There is somewhat of a controversy about the protein bullets. (New Whey is one of the brands I used in the past) The protein that they use is a collegen based protein which allegedly isn't as biologically available for use in our bodies as whey or soy protein. I'd suggest doing more research on the topic. I have the bullets mainly because of the cost. They run somewhere around $3.00 per serving which got to be quite expensive for me since I need 220+ grams per day. Compare $3.00 per serving to $.20 per serving and you see the money saved. I have been using plain ole' GNC bannana cream 100% whey for the past 18 months with no problems. I hated the taste of the bullets and I hate the taste of GNC 100% whey. I choke down 40g 5 to 6 times a day and go on with my life. :)
