- Reviewed in the United States on January 5, 2016The best Casein Protein according to me. Period. I have tried all sorts of Casein Proteins from GNC, and Online (Vitacost, Amazon, Bodybuilding.com, Biotrust etc), over several years. Almost all of them have chemicals and fillers (except perhaps Biotrust and Optimum Natural) and I will get more negative side effects than benefits. BioTrust proteins is a mix of why and casein blend, and they are very costly, and they do have larger amounts of Stevia, Inulin, sugar alcohol etc..Though reasonably healthy, BioTrust cost and the "fillers" put it out of reach for most. I also did not have any positive results from this brand. Optimum Natural Casein was my first choice till recently. Reasonably pure (at least no synthetic chemicals and junk), and decent price per pound, and average benefits. But I recently started on Naked Casein, and I am wondering why I did not try this before! It is the purest, most healthy Casein possible! Huge 5 pound tub, and with 1 serving a day, will last you 75+ days! Even with 2 servings, for the heavier users, it will last you more than a month, and it is very decent price/pound. The quality is amazing! I had great results within a week of using it. No gas, no bloating, no issues! I have used it in the night before sleeping, and have also had it during the day. And I felt energetic and wonderful. My sleep is good, no disturbance, no stomach issues. My recovery seems better. I seem to have gained positive results in the muscle department also, in just this 7-10 day period! (that is the quickest jump in results I have ever had in many years of working out). I am using Naked Whey and Naked Casein together now.. as my only protein supplements. Threw out everything else!
Like many have said, it does not mix that easily by just stirring. But I am ok with the lumps! How does it matter? :) Why take more time with blender/mixer/shaker etc? :) Also, like some reviewers have said, it tastes just like diluted milk/milk powder. I do not need to add anything else, and can just have this powder with Water. However, I have added a dash of "Amazing Grace Green Superfood" powder at times, and not only does not help with better mixing, the shake tastes even better, and it is even more healthier! (You can even add a dash of Unflavored vegan protein powder like PlantFusion. No added sugar or extra calories, and better taste and a healther shake! I have also tried it with diluted Yogurt or Buttermilk, and this powder tastes great with all of them!
Because my feedback and experience with Naked Whey and Naked Casein have been similar, and beyond my expectations, I wrote a detailed review for both products, and any of you looking at my reviews of Naked Whey, might notice an overlap of some of the info :) But both the "Naked" products are outstanding to say the least. I recommend that you do try it at least once.
- Reviewed in the United States on February 5, 2016I rarely write reviews but feel compelled to do so for this product so that more people get turned on to it and they keep making more. To the best of my knowledge and research, this casein protein is the only one of its kind. No fillers, additives, crap or junk that most of us can't pronounce or are aware of for its use or benefits.
Just simple, effective, muscle building casein protein. Period. It tastes fine to me and isn't chalky or grainy at all. I do however prepare my shakes/smoothies by adding a banana, naked peanut butter powder and then blending via a blender. The blender I got specifically for this lifestyle change of mine was the affordable yet perfect Hamilton beach smoothie blender. It was only $43 on Amazon and does the job perfectly.
Now I enjoy amazing smoothies with even better protein that is both beneficial and clean to consume whenever you need it. Thank you naked nutrition for making amazing products that reflect a clean living lifestyle.
- Reviewed in the United States on June 15, 2015This casein is real and pure. I know because it's thick and tastes like thick foamy watery paste. Micellar casein is the highest quality casein you can get and is equal to hydrosylized whey. I actually can't stand the taste but it is keeping me lean and muscular. I take it at midnight and don't have hunger pangs in the morning so I know my muscles have been fed all night. Nothing artificial in it. even though I can't stand the taste its fulfilling in a clean way. No digestive problems. No gas. Lean gains. My woman does not complain that I would spend this much on casein because it yields great results for building muscle.
- Reviewed in the United States on July 29, 2019If there is some other reason to consume this supplement outside of some type of training regimen I am unaware of it. So I will write my review with that in mind. Arnold, who most consider the GOAT in the world of bodybuilding, answered when asked about people who have trouble sticking to diets with another question: “It’s really simple. What’s important to you?”
I have read the one star reviews of this product and I find them comical. Does this product mix as easily as Whey? No. Does this product taste as good as Whey? Nope. With the best blender the shake is sometimes a bit clumpy, sometimes a bit frothy, and it’s always chalky tasting. But Whey and Casein both have important and different roles to play in your weightlifting supplementation. I’m not going to get into what you can find hundreds if not thousands of articles telling you about how they are both to be used, but just that they both have a place.
So then it gets back to the point Arnold was making. If eating over-processed fast food and junk food all day because it “tastes good” like the majority of people is what’s really important to you, then do that. If your goal is to get bulky or shredded and gain muscle mass it involves making time to train, and a sacrifice on your part to view food and supplements as fuel to achieve a goal. If you’re too much of a baby to be able to get down Casein, then you aren’t going to make it.
- Reviewed in the United States on March 12, 2025The item I received had black mold in it. It smelled very foul and was contaminated by moisture. I have taken pictures and sent the manufacturer an email with the issue. The black mold was everywhere around the inner seal and the top of the bottle.

5.0 out of 5 stars Very easy to use; tastes good.
Based on the reviews, I anticipated a difficult to handle powder needing a high speed or a stick blender, or at the very least, a shaker bottle. I put 15grams of powder into a thin tall beaker, poured about a tablespoon or so of milk over it and stirred with a chopstick to see how long it would take to incorporate. I was surprised that it very quickly changed into a paste, or pudding-like consistency, and the lumps quickly smoothed away (not even half a minute). A tiny bit chalky in taste, but not unpleasant, and with a slight powdered milk flavor. It made a nice pudding with a bit of sweetener, dried coconut flakes for texture, and a few almonds to give it some crunch. From the paste, it incorporates any liquid easily, just by stirring with a spoon. Adding milk to it makes it taste like milk, without thickening it.

5.0 out of 5 stars Does what it says for better and worse
If you know you want a pure casine with no sweetners or fillers this product is exactly that. The trouble I've had with it is trying to find a way to take the stuff that doesn't taste awful. The powder has no flavoring or additives so it mixes poorly and tastes like 1980s powdered milk. Best I've found is adding a shot of Nesquick to cut down the foam and give it some flavor.
- Elisha M.Reviewed in Canada on September 5, 2024
3.0 out of 5 stars Anyone who tells you it tastes good is lying.
First of all it doesn't taste good. It's not horrible but far from good. (Very far). The consistency is between powdered chalk and sand. It may also taste like that as well. It's so thick it clogs the top of my shaker. Also mixing with milk does not change or mask the taste.
Pros:
It's clean. Extra protein and calories. Slow release.
- BawajiReviewed in Canada on August 19, 2018
1.0 out of 5 stars doesn't mix well, extremely frothy, difficult to drink
I really wanted to love this product, especially since I'd tried your NAKED Grass-fed Whey Protein and loved it. However, my experience with the naked casein was really lacking. I tried mixing the powder in multiple different kinds of drinks (water, milk, juice, etc) but no matter what I do it always ends up foaming up to the point where over half the drink is foam which doesn't settle. And it's not even possible to try and chug down the foam and liquid that's left, since there's always specs of powder that didn't mix properly, leaving a very chalky and dry sensation in the mouth. To me, these issues were a deal breaker. But if those are things that don't bother you, than this product is amazing in terms of being ultra-pure (no fillers, emulsifiers, sweeteners).
- SwixzzleStarReviewed in Canada on July 31, 2024
4.0 out of 5 stars I did this 3 times
I made this review 3 times and it didn’t post or stick. So I’m making this review as little as possible because the very good one I made was erased and now I don’t give a flying f about the review as Amazon keeps ruining it.
It’s decent stuff, I bought a lot of powders and this one doesn’t have the weird texture. Has no flavour but still leaves a very milk taste. All products (as I have all them) all have the milk taste. Other than that it’s not bad and blends well with your smoothies.
I gave details last 3 times so this time is a basic and lame review because it probably won’t stick and Amazon will make me do it again.
