Best protein shakes?

I've never really had protein shakes, but I've heard it definitely helps with weight loss. I've been running about 3 miles every day, eating really lean and have lost 7lbs so far! 💪🏼😼 Does anyone have any good suggestions for protein shakes? I'm thinking I might use it as a meal replacement for lunch at work so I'd def need something to keep me full for a while.
