I just found a wonderful whey protein by Quantum Nutrition. It is on the pricey side but it's clean New Zealand whey with probiotics! Which is really a perfect choice for primal lifestyle because if you don't eat dairy, it's a good way to get probiotics. Tastes really good too and no added sugars or anything.
