Customer Reviews

Just what I need and nothing I don't
What I love about this products and others distributed by this company is that they only contain what you order. I am so glad that there are not a bunch of other ingredients in the products the provide and this protein powder is no exception. It tastes great, keeps me fuller for longer, and is very versatile which allows me to add it to or add to it to make a tasty shake into a meal. Love it!*

Not all Casein is the same- this one proves it!
After trying many others that literally were talking me out of this type of protein. My insistence is that casein digests slower than others so it is a great alternative for those of us who need our protein before bedtime. To be honest, I was expecting this powder to have the same grittiness as all of the others I have purchased and just to make sure no stone is unturned, I prepare my smoothies in a Vitamix. I was taken by surprise when the fruit smoothie turned out quite smooth, there is no grit and no aftertaste either. Instead, the flavor of the berries and the piece of banana came thru and was delicious. I had to add a couple of drops of Stevia because it is not sweet or flavored. This was even better because I am certainly going to try with other things. I am providing this review not because I received the sample but because I think this is a great product and the price is quite competitive. I store mine in an air tight container and keep it next to the vitamix but the bag is good enough for that as well. Good job on this product! *

Casein Protein Powder
Great product. It arrived in a timely manner. It mixes well in my blender bottle and gets the job done. Buying this in bulk is definitely a good move!*

On 8/31/2016 Ethan said...

Casein Powder
Great product, neutral flavor for easy mixing with anything. Great for taking before bed to maintain a positive nitrogen balance while sleeping.
My only gripe is the zip locks used on the bags, not always easy to reseal.*

On 8/30/2016 James said...

Casein Protein Powder
This was the first time I've purchased anything from the site. The product arrived quickly and was everything it claimed to be. I mixed it with my chocolate whey protein to give it some flavor. The product mixed well and tasted as well as I could expect. I will be purchasing this product again.*

On 8/29/2016 Sean said...

casein protein
Great quality protein. Trust me you'll notice a difference the moment you open the bag. Another great product!*

On 8/25/2016 Tim said...

Excellent powders
This is the second time I have purchased Casein Protein Powder and will continue to do so. Pure powder without all the other junk mixed in. No bad odors are taste. Three times daily I mix 10 grams Casein with 10 grams Grass-Fed Whey Protein Powder add about 6 oz. of distilled water and shakes up well in my 8 oz. mason jar. Excellent powders. *

On 8/21/2016 Gary said...

Casein Powder
This supplement is great, it provides all the nutrients I need while being easy to mix and easy on the stomach. I often have issues with supplements making me feel sick but this has no ill side effects on me. I do have to keep it in a gallon zip lock bag as the zipper in the packaging does not function correctly*

On 8/9/2016 Brian said...

Casein Protein Powder
I have seen good results in my muscle gain using Casein powder. Little thick so need to blend it in a blender. No additives. I take it before going to bed on my workout days to continuously feed my muscles during sleep time.I am re-ordering it. A good product.*

On 8/2/2016 Tahir said...

great product
the casein powder has been working great for me. no upset stomach. it seems to be more effective than other brands probably because there aer no extra additives. will return to rebuy. *

On 7/16/2016 Dave said...

casein protein powder
Love the product and the company! I mix it with the whey, milk and frozen fruit, tastes just like a milkshake... I won't order from anyone else!*

On 7/1/2016 Brandi said...

Very pure product protein
I purposely waited to review it in order to try other casein proteins on the market. What I must say is that the protein that I received from this site was much purer than the others that I have tried. Sure it doesn't have all of the "bells and whistles" that the other brands offer, but at the end of the day, I would choose this brand over any other. I have NEVER received any products from Bulk Supplements that I didn't enjoy. I guess that is why I keep coming back to them again and again. Keep up the good work!! *

Casein Protein Powder
I have been using whey protein for years and recently began using casein. This product is tasteless and mixes easily. I use it in smoothies, mix it in my oatmeal, and add it to my yogurt. I have even mixed it with just water when in a rush, and while it was quite bland, it mixed well and was somewhat smooth and creamy. I definitely recommend this product.*

On 6/19/2016 Michael said...

Protein Powder
Love the Hydrolyzed Whey Protein Isolate Powder after trying a sample. I ordered a larger size and plan on getting more in the future.*

On 6/19/2016 Paul said...

Good for the money
The product is as described, pure powder. Tastes chalky when mixed with water or Gatorade. Milk does it justice as for the taste. Mixes good without clumping in any liquid that I used.No bloating (gas) observed, like with normal whey protein, when used on a daily basis.
The packaging needs improving. Zipper on the bag was very hard to shut after opening. I just threw the original bag away and used a ziploc sandwich bag to store the rest of the protein. I had the smallest quantity so obviously larger quantities would need something larger than a sandwich bag to store.
Its hard for me to give anything five stars, if the packaging was improved and there was some taste to the product I would give it four stars, but overall it's a good product for the money.*

On 6/18/2016 Kirk said...

Pure & Tasty. That Bag Though........
Love that this company sells a pure casein powder with no additives or nasty other ingredients. I warm up rice milk before bedtime and add a few scoops of protein with cinnamon. Yum! Don't go to bed hungry & sleep like a baby. Can never quite get all the clumps out by shaking. Ziplock bags don't work. Period. Need to clip or rubber band them. *

On 6/15/2016 OlyPrincess said...

Great Casein Protein
If there was an option I would give it 4.5 stars…
The only downside to this product was that it was a little clumpy, so make sure that you have a high-quality shaker or use a blender. Besides that, a great product that I will surely purchase again. It is refreshing to look at the ingredient label and see only 1 item and not a laundry list of additives, preservatives, and flavorings. I don’t usually add anything to mine, but occasionally mix in with powdered Gatorade.

On 6/7/2016 Todd said...

Casein Protein
Tasted good and dissolved pretty well. Good amount of protein, great to take at night before bed. Definitely planning on getting more.*

On 5/25/2016 Michael said...

High Quality
A great slow digesting protein. Better than most unflavored powders and mixes well. Drink it right away before it thickens. *

On 5/25/2016 Taylor said...

fine casein
this works well.It's clean and pure as stated.
p.s I thoroughly research what I ingest and this protein is clean plus the price is top notch.
this will be my new place to buy protein:)*

On 5/25/2016 Jason said...

Casein Protein Powder
Good product. Excellent price. Clumpy and foamy when mixed but that's expected because its raw product. Taste like watery milk without anything added. Tasteless when something is added. *

On 5/23/2016 Harrison said...

mixes well, good taste, reasonable price
drink before I go to bed. slower digesting protein source. almost no taste and easy to mix. perfect. *

On 5/6/2016 jeff said...

Good Product
This is an unflavored protein so it isn't your typical protein powder as far as taste goes. Tastes like milk to me.

Seems to be a good product with no added, unnecessary ingredients. *

On 5/4/2016 Chris said...

slow protein drip
I got this for the slow-digesting properties and have been very pleased with the taste and ability to mix with milk in smoothies or with thawed previously-frozen berries.*

On 4/20/2016 Greg said...

A great protein
This is second order for Casein. I take it at night as a final snack before bedtime. I usually mix it with water and drink it straight like that since it doesn't clump or thicken up as much when mixed with milk.
When I do mix with milk, I use my ninja blender to get all the clumps out but it still comes out thick, which is not a big deal to me. Will continue to purchase this from*

On 4/15/2016 Tom said...

Great Product!

Mixes Well!

Taste is not bad at all!

5/5 Will order again! *

On 4/14/2016 Steven said...

Excellent befoer bed shake
A slow digesting protein is great for keeping you full while you sleep. I've used many different brands of casein powders over the years and this one is truly my favorite. No added sweeteners or fillers, mixes very easy with your liquid of choice, and very fare pricing makes this a must have product for any level bodybuilder.*

On 4/5/2016 kevin said...

I put two scoops into a shaker blender bottle with water, shake it up, add orange flavor and ice. I drink it between breakfast and lunch and again between between lunch and dinner. Does a good job of keeping me from feeling like im starving. The bags dont reseal all that well, I long for the good ole days of jugs.*

On 3/20/2016 Larry said...

Great for mixing with Whey
Loved this product. I have routinely bought whey protein isolate but hear that blends of fast and slow digesting protein are optimal for muscle growth. Tried this product alone and combined with whey. Works great. Mixes well and best of all no artificial flavors or colors.*

On 3/9/2016 Kevin said...

Great addition to my morning shake
I had heard that casein can have a clumpier texture, but I found by adding a little casein to my morning post-workout shake, it blends fairly well, and the taste isn't very noticeable. I also notice it keeps my hunger at bay for a little longer in comparison to a plain whey protein shake. Definitely a great addition!*

On 2/8/2016 Mary S. said...

As usual, the casein I received was just as advertised. Compared to whey, it has a stronger milk/cow flavor and a grainier texture. It also clumps a little more easily, but not too badly, because the casein is “instantiated,” or coated, with soy lecithin, which makes it more easily dissolvable in a liquid. Consequently, it is not exactly “pure casein.” This is best for most people’s purposes, however, as it was mine. I use it to boost the protein content of one of my favorite beverages: milk. My only complaint with the product is that the ziplock-style seal did not work, so I had to put the casein in a new bag.*

On 1/16/2016 Shane said...

Casein protein
Awesome! No fillers no bull$ht additives, this is by far the best casein protein I have ever bought. I have reordered multiple times.*

On 1/11/2016 John said...

Simple, clean
Love this product - no other additives and it mixes nicely. Great combo with Whey from BulkSupplements!*

On 12/22/2015 Chris said...

Casein Protein Powder
This is a nice addition to any stack, it mixes nice, no fillers no extra unneeded calories in it just pure casein protein. I use this and whey from this site I recommend both highly. I have place multiple orders for both casein and whey, never disappointed.*

On 12/9/2015 John said...

Much better than I expected since Casein is thick and isn't as tasteless as Whey. This stuff is about the best you will find!! Mixes well, no taste!*

On 10/24/2015 Kerry said...

Flavorless and clean
Unlike all other powders I've used through the years, Bulk Supplements is flavorless, so is perfect for adding to water or almond milk. My only concern is that it doesn't perfectly dissolve in water. Need to figure this out!*

Casein protein
This is without a doubt a great pure protein, it mixes great with any stack, I have placed multiple orders for it. 5 stars.*

On 10/20/2015 John said...

Excellent decision in ordering this suplement
This is my second order from, and I'll continue dealing with them. The shipment arrived fast and in excellent packing. This time I've ordered the Casein Protein Powder as well as the Grass-Fed Whey Protein Powder and I love them both. They mix nicely and the taste is very neutral so it helps me a lot in making my own smoothies. The only downside, as other reviewer mentioned is the zip lock mechanism it won't closes after the initial opening of the product. Other than this, I'm very happy with the products.*

On 9/25/2015 Nezar said...

High Quality Protein
This protein has a very neutral taste and mixes well in my smoothies. The texture of a smoothie made with casein protein is thicker compared to one made with whey protein. I am very satisfied with the product and plan to use it at night since casein protein is absorbed at a slower rate than whey. Bulk Supplements needs to pay greater attention to their packaging. The zip lock mechanism was broken when I opened the pouch, so I have no way to close it.*

On 9/24/2015 Brian said...

Very satisfied
The taste is bland and borders on being tasteless, which I appreciate. I haven't had any problems with clumps. I've been mixing it in my blender with other smoothie ingredients and have noticed increased energy. I'll be ordering this product again!*

On 9/16/2015 Jessica said...

Excellent Addition to Any Supplement Stack
I have been taking casein before going to sleep in addition to supplementing with whey protein after working out, and I've discovered a number of benefits to this pairing. I've noticed no hunger during the night; the casein really does seem to be slow digesting! My strength levels also have increased on this pairing, so I intend to continue using casein. I would recommend it to anyone interested in getting the most out of a bulking period; I know it's helped mine!*

On 9/15/2015 Joseph said...

Casein Protein Powder
I recently ordered Casein Protein Powder and I love it. It mixes nicely, I order both this and Whey from bulksupplements. The protein products are pure and the real deal.*
