Optimum Nutrition Gold Standard 100% Casein Slow down the rate of protein digestion – not your performance! Gold Standard 100% Casein by Optimum Nutrition contains – as the name suggests – 100% of the dairy protein Casein to help with recovery, boost muscle growth and reduce muscle breakdown while you sleep. This slow-digesting protein releases amino acids slowly over a long period of time. This process can help your cells synthesize protein during times when your body might normally be breaking down its own muscles to energise itself. While athletes and bodybuilders use fast-digesting protein immediately before and after their workout to help refuel recovering muscles, slow-digestion is more beneficial at other times including bedtime when your body typically goes for hours without food. Slow-release protein. 24g of anti-catabolic micellar casein per serve. Over 4g BCAAs per serve. Over 5g glutamine & glutamic acid per serve. Optimum Nutrition Gold Standard 100% Casein is “anti-catabolic” and helps reduce muscle breakdown, making it the perfect slow-release protein to add to your supplement stack. It is also rich in antioxidants and prohibits the rise of dangerous free radicals. Optimum Nutrition Gold Standard 100% Casein contains essential and non-essential amino acids, as well as the BCAAs L-Leucine, L-Valine and L-Isoleucine plus 5g Glutamine & Glutamic Acid per serving for optimal regeneration of damaged cells and recovery.

Best vanilla protein I've had, vanilla is a hard one to get right. I use this to make Konjac Rice Pudding, just mix like 8 packets of Konjac rice (with almost no calories) plus some water and heaps of this vanilla protein. You'll know when it's ready when it gets really thick and goopy and almost impossible to stir, and all of the lumps have gone. BTW it doesn't form lumps in a shaker, just when I mix it this way by hand. This "rice" pudding is delicious and has helped me a lot in my weight loss goals. It's got a very nice vanilla and sweet flavour, the thick consistency is very good, and if you add lots of orange blossom water, lots of extra vanilla extract, and some rose water, as well as cinnamon, it's almost as good as real rice pudding.

For too long I had relied solely on whey protein to help build muscle, especially after intense work outs. It definitely helped, but often times I would wake up the morning after not feeling that much better. In other words, I wasn't really recovering that well. I considered just doubling up on the whey, basically eating another serving before bed, but then I did some research.I figured it would benefit me to alternate the types of protein supplement, and when I added the Optimum Nutrition Casein protein, it was a game changer. I now wake up in the morning feeling back to 100%. Even though I never train the same muscle groups two days in a row, I feel as if I could. I am making a 100% recovery in less than half the time.As a side benefit, the stuff tastes ... MoreFor too long I had relied solely on whey protein to help build muscle, especially after intense work outs.

I mix mine with soy milk (yeah, I drink soy, get over it) and shot of light cream, after reading that a modest amount of fats help the body absorb large amounts of protein. Anyways, the vanilla is a very deep and satisfying flavor. To change it up I sometimes add some cinnamon powder, or some nutmeg and ground clove. On top of that, I eat it just before bed, and I am never super hungry in the morning, and I have eliminated my midnight snack routine.I use a hand crank egg beater to mix this stuff up, because even a little bit quickly turns into a thick mixture, sort of like wet concrete. It needs way more liquid to dissolve into than whey protein powder. Sometimes I also throw in some Greek style yogurt, but this stuff is thick enough already. The labeling says something about how Casein behaves differently when it hits the acid in the stomach, and that it expands, and you see this when you mix it up.If you have been missing something in the protein department, I would absolutely try this Casein.

Such a great supplement for bodybuilding. Really pleased with the quality, having tried other brands like myprotein which are cheaper but very poor in quality compared to Optimum Nutrition. Blends well with no mess or froth. Great to have before bed for best use. Would recommend again! Strawberry flavour is amazing!

Delicious chocolatey taste
21 February 2023

Optimum's chocolate casein has a delicious taste, take it from a chocoholic. Something special about the casein is it gives your shake or pudding a very thick texture. Much more than any other protein powder I've used. Best to use casein as a meal replacement or before bedtime snack.

Great taste
16 October 2021

I'm relatively new to the protein powder game, but this stuff is great. Even with just water it has a nice creamy texture and great flavor. I usually mix it with coffee and oat milk though, and it's terrific. My girlfriend also made a protein dessert bar with them and it tasted really good. I don't know how to quantify the effects in all honesty. But for me this works and tastes great. Oh and I got the chocolate flavor just for reference

I've been using this product
18 April 2021

I've been using this product for almost 5 years and it was the best casein I've ever tasted. Up untill the latest redesign of the product. The label is just a bit different so it's not that obvious, but as soon as you open the box you can notice a completely different product inside. _x000d__x000d_The powder is no longer a bit 'grainy', but smooth like wheat powder. The smell is almost the same. The old product you could mix it just with a spoon easily. In milk or water. Now with the new product it's almost impossible. Powder sticks to everything._x000d__x000d_I'll never buy this product again._x000d__x000d_Note: I'm from Europe and I know it's produced in the UK or Ireland for our market, so maybe in the US you're lucky and they didn't ruin the product

Loved it till they raised the price massivly
7 November 2022

My son uses this to cook so many of his healthy foods with. He loves it only the last 8 purchases we wondered why it went from $39 to over $55 bucks plus or including tax. We are now going to stop buying from here due to the inflation and go with another product. Sad because we were an every 2 day buyer of this product.Like I said my son loves to be healthy and make healthy yet bad for you looking treats so we stick to healthy over junk. He is 17 and so into this product abd whey protien that he has taught himself so many cool ways to cook. Bake, and use this. Sad to have to go somewhere else for it.

Smells like SunBum spray sunblock
2 October 2022

This smells like SunBum spray sunblock -- tropical, coconut-ish. It's not a bad smell (especially for sun block). But it's off-putting for a food item. It is easy to mix (much easier than the out-of-stock-for-months Beyond Raw ISO Casein PM). Flavor is okay, not terrible. And I could get used to it if I had to. The picture of the ingredients label still shows Yellow #5 but I don't see it on there now, so that's good. Am going to try something else (and since everything at GNC is out of stock re: casein that means a completely different brand). If I had to come back to using this I would.

Weird consistency, even more weird taste
2 August 2019

IDK how this casein keeps getting such high reviews. Compared to Kaged Muscle (Vanilla) this is garbage. The flavor is just awful. It’s like an artificial vanilla almond? Also, the consistency in the of it (before mixing) is very fine; to ONs whey & and hydro-whey (which I use and enjoy). I’ve not had a problem getting it to mix. Either shake more or don’t use ice cold water! Add ice after it’s mixed....Bing search “consistency for casein powder:Casein protein powder’s ability to clump up is useful for more than just slow digestion. When the proteins in casein form a clump in the stomach, they keep you feeling full for a longer time. Since that casein powder clump takes up space in the stomach, those hunger signals will be delayed.I would’t recommend this ... MoreIDK how this casein keeps getting such high reviews.

Works Great for Protein Ice Cream!
9 August 2021

I’m getting into making my own ice cream and tried with their whey protein powder with almond milk. Something just always seemed off. I decided to try it using casein because I heard casein has a thicker consistency and omg! Game changer! The mix was nice, creamy and thick! With the whey, it seemed watery and the taste was a little off. With this, I honestly could not tell that it was protein powder. I let my husband taste the ice cream and he thought I bought it! Absolutely delicious. Who knew ice cream good be so healthy and taste so good!
