I have at least one per day to supplement my protein. Usually I have one that has 26g in the powder scoop, then add it to 1 cup of milk which then makes 36g! Or I enjoy the Trader Joe's already prepared protein drink that has 35g. Both are quite tasty.
I used to do one protein shake with milk a day, it was like 36g of protein each shake, but my dietician told me the body can't absorb that much protein at one time, and to split my shake up to half a scoop twice a day..
