The Natures Best Isopure protein powder has 50g of protein in 2 scoops if you fill a blender bottle with skim milk and 2 scoops of that it equals about 72g of protein for the whole bottle when you add in the protein you get with milk. I use the blender bottle that hold about 20oz. I usually drink the one shake throughout the day. Also Greek yogurt has lots of protein.
