Optimum Nutrition's Gold Standard 100% Casein is a top-tier product in the world of protein supplements. As someone who values slow-digesting protein sources, this product has been a game-changer for my fitness routine and overall nutrition. One of the standout features of this casein protein is its slow-release formula. It's perfect for those looking to maintain a steady supply of amino acids throughout the day or to support muscle recovery during the night. This slow digestion not only helps with muscle growth but also keeps me feeling fuller for longer, which is a great bonus if you're watching your calorie intake. The taste and mixability are impressive. It mixes easily with water or milk, creating a smooth and creamy shake without clumps. Quality is paramount when it comes to supplements, and Optimum Nutrition is a trusted brand known for its commitment to quality and purity. The Gold Standard 100% Casein is no exception. It's made from high-quality micellar casein, providing a clean source of protein without unnecessary fillers or additives. I also appreciate the versatility of this product. It's not just limited to shakes; I've used it in recipes like protein pancakes and yogurt, adding a delicious protein boost to my meals. While it's a bit pricier compared to some other protein options, the quality and performance make it worth the investment, especially if you prioritize slow-digesting protein for your fitness goals. Overall, Optimum Nutrition Gold Standard 100% Casein is a reliable and effective choice for those seeking a premium casein protein supplement.

Nice taste, but thick texture. A bit difficult to dissolve for shakes but is brilliant to make protein pudding dessert!
My first attempt to make a protein shake with this Casein powder wasn't very successful, as it doesn't dissolve as well as whey protein, even with a shaker (I found that mixing it first in a bowl/glass with a small amount of liquid then adding more liquid is easier to dissolve it properly. I actually took advantage of the thick-high absorbing properties to use it to make protein pudding, with the following proportions: 20g of casein powder, 70ml of unsweetened almond milk (or other milk), 50g of fat-free yogurt, 3g of unsweetened cocoa powder, 5g of peanut butter, mix well and chill in the fridge for 30min at least, it will get smoother and thicken even more resulting in a delicious chocolate peanut butter mousse/pudding. It tastes like an indulgent dessert for only150kcal : 21g protein, 6g carbs of which 3g of sugar, 4g of fat (good unsaturated fat from the peanut butter). Being low in sugar, it's healthier than most desserts and it has also replaced my usual chocolate fix! I agree with another customer on a kind of "cappuccino"-like smell of the dry powder, but once dissolved the chocolate taste is nice. I have also tried the vanilla as a sample, which tastes like vanilla ice cream. Both are properly sweetened for most people taste I think, however I have cut my sugar consumption for the past two months and being more sensitive to any sweetness, I now find it a bit too sweet to my taste, but I will keep buying it anyway.

Quality product, if a little difficult to mix.
This casein was purchased because I wanted a slow release protein that I could use after an evening workout. I am familiar with other products in the Gold Standard range, so for me this choice was a natural one. The taste is good, without tasting overly artificial like some other proteins. Like most supplements it does take a little getting used to the taste and consistency, however I would now rank the Chocolate flavour as my favourite. The only criticism I have (hence the 4 stars) is that it does not mix as easily as whey protein. I'm not sure if this is true of all casein products or just this flavour. With that said, it does mix 100% in the end, it just need a bit more shaking than normal and also ends up being a thicker consistency than others, meaning more water also needs to be added. Not really a downside, just something to note. This has a small knock-on effect of cleaning being a little harder to. Recommended.

Taste review
I'm no Bodybuilder, so can't really rate on performance, but I want to get more protein into my diet & to keep that protein intake up through the night whilst sleeping, I read that Casein was the way to go, so I've been drinking this stuff just before bed for about a week now, when I first opened the tub, it had a very strong smell, overpowering, almost like cappuccino, which I can't stand! so I was a bit worried, thinking I've wasted my money here, I followed the instructions, I made it up in my shaker & was pleasantly surprised when drinking it, it certainly tasted like chocolate, in fact it was delicious, it was thick n creamy (I use unsweetened soya milk) I'd like to add, I am a chocolate bar lover, but not really keen on Chocolate Milkshakes, but this stuff is delicious, I now do not crave my night time bar of chocolate, because I now know at bedtime I'm going to be having a delicious creamy Chocolate milkshake, in fact I actually really look forward to this drink at night.

Great tasting casein protein that mixes well
I’ve been using this casein protein powder regularly and it’s been really good. The chocolate flavour tastes great and mixes well, especially for a thicker shake before bed. It’s a convenient way to add extra protein to the diet and the quality is what you’d expect from Optimum Nutrition. Overall a solid casein protein that I’m happy to keep buying.
