This shake is fine as long as you don't get digestion issues. I found that people who use a lot of liquid egg white end up with stomach problems over an extended period. But if you are just doing it for one meal, it’s totally fine. Through the pasteurization process, the protein is slightly denatured and will absorb better than cracking raw eggs. Just watch digestion and if thats good, you are good to go! From experience with clients though, I would suggest using it no more than 2 cups a day
