This protein is great. I wouldn't say it is 100% unflavored but I think its the closest you can ever get in a protein shake. In the winter it tastes good mixed in a nice warm cup of hot chocolate and in the summer it tastes good as a shake. It mixes well. It doesn't taste grainy and if you leave it sit for a while it doesn't get all clumped up. If I eat in the morning no matter what I eat it will upset my stomach. Unjury never upsets my stomach. No gas. No diarrhea. No abdominal pain. I love it love it love it!
