  • Excellent Casein Protein, Great Taste, Mixes Well, and Works Exactly as It Should
Flavor Name: Chocolate Size: 5 Pound (Pack of 1)
I’ve been using Nutricost Casein Protein Powder for about six months now, and it has become a steady part of my daily routine. The taste is surprisingly good for a casein protein, and it mixes much smoother than most I’ve tried. I like taking it at night because it keeps me full and helps curb late-night snacking, and I’ve noticed better muscle recovery the next morning. It’s also easy on the stomach — no bloating or heaviness. Overall, this is a high-quality casein at a very fair price, and I’ll definitely keep buying it. ... show more

  • Good protein
Flavor Name: Chocolate Size: 5 Pound (Pack of 1)
This powder has a nice chocolate flavor. It blends well with water in the shaker bottle. The cost per serving was amazing.

  • delicious, thick, great price
Flavor Name: Vanilla Size: 5 Pound (Pack of 1)
I've had tubs of the vanilla, chocolate, and unflavored. All are great. Unflavored - not a pleasant flavor. Adding flavorings and cocoa powder mostly masks it. Texture is thicker than the flavored ones. Chocolate - like a chocolate milkshake. Vanilla - doesn't taste like vanilla, but more like butterscotch candies. I actually prefer this over a plain vanilla flavor. I'd give the same 5 star rating for those 3 flavors ... show more

  • Good for gainz - If you're mentally strong enough
Flavor Name: Vanilla Size: 5 Pound (Pack of 1)
Review updated after 1 month It took me some time to get used to the taste and texture. If I could give one piece of advice, I would recommend using about 400 ml of water to mix two servings. While it may not be the most enjoyable protein in terms of taste and feel, I’ve gotten accustomed to it, and I now actually look forward to having it before bedtime. The flavor is a very mild vanilla, which makes it easy to adjust to your preference.ld vanilla, which makes it easy to become adjusted to it. As far as gainz are concerned, mine are mostly of the newbie variety of a man who hasn't worked out in over 10 years. While muscle memory plays a role, I have found that consuming 1 gram of protein per pound of body weight has significantly boosted my strength in various compound lifts. In fact, I've nearly doubled my strength in just a month. I believe that Nutricost's casein protein, in addition to whey isolates and creatine, has helped prevent me from going catabolic during rest cycles. I would highly recommend it to anyone looking to enhance their strength training. I know the plateau is near, and gainz will be harder to come by, but I'm loving what this protein is doing for me. ----- First of all, before getting into the nitty/gritty (literally), this protein has an amazing price point. It will no doubt serve the goal of an overnight protein source well. If you were expecting a good experience in terms of taste and texture, think again. This product is very different from hydrolyzed whey. It has a thick, gritty, and powdery consistency and is almost flavorless. While it doesn’t have a dough-like texture, it is quite unpleasant. The only other option is to use a lot more water, which further dilutes the flavor into nothingness. Objectively, this may suit your overall goals for gains, but if you have any concerns about unpleasant textures, you should consider choosing a different brand. It's really hard to choke down. ... show more

  • Mixes well, tasty, seems healthier than some alternatives
Flavor Name: Chocolate Size: 5 Pound (Pack of 1)
Our all-time favorite casein protein powder (we rarely do whey protein--don't like the texture and we've had great results with this slow-burning protein) was Dymatize Elite Casein in the "rich chocolate" flavor. Absolutely delicious and fantastic consistency. BUT, for anyone health-minded, looking at the ingredient label was hard to stomach. Lots of fillers and especially the presence of ingredients known to be bad for gut health (e.g., Xanthan Gum). At the end of the day, yes, they both have sucralose (another name for Splenda) in them, but the ingredients in this product are far more appealing (and simple) than those in the Dymatize. Ideally I'd love to see an option which used say monkfruit + allulose as the sweetener. As far as "clumpiness" this mixes really well. You just have to know what you're doing with casein protein powders in general in order to mix it smooth. We use a Ninja Bullet blender for our protein shakes and it works great. Very smooth and creamy result. It's also pretty mixable and smooth and creamy just with enough water. The less water you use the thicker it'll be. I've tried MANY protein powders and if you don't like this one I'm not sure if you'll find any that you do like. I'm very picky about taste and texture and relative healthiness of ingredients, and for me this is (on the whole) about the best you can do. Plus it's actually about as affordable as they get. Some of these protein powders are insanely pricely (looking at you Dymatize). So this is a great combination: it's an affordable and effective and tasty protein powder. ... show more
