WheesaWell, I would not recommend the one I was having before. But I am trying fish collagen from isopure. Try that one
afartinthehandIsopure unflavored. 25g per scoop and lots of other good stuff.
alanthianaIsopure's unflavored has no sugar or sweeteners.
Ambitious-Wait-5705Unflavored Isopure for me. I’m adding it to stuff, so why would I need odd flavors? Too bad Costco doesn’t carry it, but the Amazon price is okay.
AndriannaPThat's the one I use, too. I add 1/2 scoop into my coffee and don't notice it at all.
Awkward_Priority_476now protein is one area where you really don't need to overthink it. for unflavored whey that's NSF certified, i've had good results with optimum nutrition gold standard - their unflavored version mixes decent and doesn't taste like chalk water another option is isopure unflavored, bit more expensive but really clean and no weird aftertaste. both are complete proteins so you're covered there honestly the vanilla flavors from most brands are pretty rough, unflavored is way to go if you're mixing with other stuff anyway. just make sure you're getting enough water in the mix or it gets clumpy fast
