So I am really, really struggling with liquid protein and I'm trying different things. I have found that bariatric hot cocoa, while a bit too sweet, is much more tolerable, and it has 15 grams of protein, and if I make it with Fairlife milk instead of water it has even more. The thing is, the protein source is calcium caseinate, and I see things like whey protein concentrate or milk protein concentrate in most products. Is calcium caseinate an adequate source? Does it even matter what kind of protein it is: whey, soy, pea, rice, etc.? Thanks in advance!
