No Chalky Aftertaste!
Flavor Name: Chocolate, Size: 14 Fl Oz (Pack of 12)
I've tried many different kinds of protein drinks, and almost all of them have either an unpleasant consistency or aftertaste. This Core Power Chocolate Protein Shake is by far the best I have ever tasted. If you place your cold drink in the freezer for about an hour and a half before drinking, it becomes slushy like a real milkshake. It is delicious and high in protein. I drink one just about every day for a quick and easy lunch.

still the best but a big price premium
Flavor Name: Chocolate, Size: 14 Fl Oz (Pack of 12)
Still the best tasting out there. drinking these is not a chore. easy open bottle. the price is the only thing, These are great for lunch replacement where you actually look forward to drinking it. every now and then my kids will get to them. it really is like a really good chocolate milk closer to a milkshake. but yea price is a touch excessive, but this protein level is the best price per gram after i ran the numbers compared to theor other products.

Great source of protein.
Flavor Name: Chocolate, Size: 14 Fl Oz (Pack of 12)
Great source of protein! It is not too sweet and the chocolate flavor is the best. There is not any nasty after taste, so they are easy to drink. My only complaint is how expensive they are.

Great Tasting and Already to GO!!
Flavor Name: Chocolate, Size: 14 Fl Oz (Pack of 12)
As someone who’s into fitness, I was looking for a tasty protein shake that I could grab on the go, and the Core Power High Protein Milk Shakes have become my favorite. This is the chocolate flavor, 14 fl oz bottles, and they come in a case of 12. Each bottle packs 26g of protein which is perfect for recovery after a workout or even as a meal supplement if I’m in a rush. What sets Core Power apart for me is the taste and texture – the chocolate flavor is rich and creamy, not chalky or overly sweet like some other RTD shakes. It’s like drinking a chocolate milk, honestly. I also like that it’s made with real milk (ultra-filtered lowfat milk), so it contains natural high-quality protein (both whey and casein) and it also has a good amount of calcium. It’s not just a thin water-based shake; it feels more satisfying and indulgent. Despite the creaminess, it’s actually low fat and doesn’t sit heavy in my stomach. I usually chill them in the fridge and it’s a nice cold treat post-gym. They’re lactose-free (the ultra-filtering removes lactose, I believe), which is great because I’m a bit lactose sensitive and I’ve had zero issues digesting these. Each bottle also has around 170 calories and they are pretty low in added sugar compared to some other brands – plus the 26g of protein per bottle is a solid dose. I find it keeps me full for a decent amount of time. The convenience is top-notch; I keep a couple in my gym bag (they’re shelf-stable until opened) and a bunch in the fridge. The 12 pack usually lasts me a couple of weeks if I’m doing one a day after workouts. It’s also a lifesaver for those mornings I don’t have time for breakfast – I can just drink one of these and know I’ve gotten protein and some nutrients in. All in all, Core Power Chocolate is delicious and effective. It feels like a treat but is fueling my body with what it needs. I’ve tried many protein shakes and this one is by far the best tasting and easiest on the stomach. Highly recommend for athletes, gym-goers, or anyone wanting a protein boost with great taste.

Good taste, convenient
Flavor Name: Chocolate, Size: 14 Fl Oz (Pack of 12)
I’m not the biggest fan of protein shakes but find these to be quite good. My dietitian recommended them as a convenient option for snacks or days when I need something quick I can grab. These hit the spot on those busy meeting days and keep me energized and full til my next meal.
