The cookies and cream flavoured casein protein from Optimum Nutrition tastes heavenly, like a creamy oreo shake. The whey version tastes terrible though
Casein protein works better than whey in creami. I use optimum nutrition
Me too. I've been using their Whey and Casein protein powders for years.
I'm using Optimum Nutrition Casein with 3.5% milk instead of dinner. It tastes good. But it's expensive as fsck.
Another vote for ON here - their Casein Chocolate Supreme in particular is absolutely the best powder I’ve used in the Creami, as it always results in super soft and creamy ice cream.
I’d disagree on Casein. I use Optimum Nutrition for both my whey and casein and the latter made so much creamier and softer ice cream than just whey (even with xanthan gum added). Both are chocolate flavoured, but the casein is chocolate “supreme”, so maybe that’s what made the taste difference.
Yes that’s the one mate. I make it with ON Casein (Chocolate Supreme) and my creami’s come out so good. I’m getting a bit tired of chocolate after a month of daily chocolate creami’s, so will be switching to the vanilla flavoured ON Casein once I’m finished with my current tub.
I thought they served different purposes; whey has faster absorption which makes it ideal for post workouts and casein has slower absorption making it ideal for adding protein to shakes or meeting your daily protein goals on certain days when you can’t get it though diet. I use both: Optimum Nutrition Chocolate Supreme (casein) for my breakfast smoothie and pre bed water-based shake Optimum Nutrition Vanilla Birthday Cake (whey) for post workouts
