Optimum Nutrition Gold Standard 100% Casein Slow Digesting Protein Powder with Zinc, Magnesium and Amino Acids, Support Muscle Growth & Repair Overnight, Creamy Vanilla Flavour, 55 Servings, 1.82 kg

I brought this to use in conjunction with their Whey protein. This is a better solution to having to consume a pot of cottage cheese before bed time. I have also started using it before I go to work. My shift work affords me very few opportunities to eat especially with no scheduled breaks. I tend to graze and this slow release protein helps to keep the amino acid levels topped up throughout the shift. The taste isn't great but palatable. It's more like creamy coconut with hints of vanilla. Mixes into a thick solution. I use 200 ml milk with 100 ml of water. Produces much less froth than milk alone. I also use a scoop and a half. Mixed using a Maximuscle shaker, and shaken for about 10 seconds. I'm pleased with the results but haven't tried any other Casein proteins.

This is great casein - I've always been a bit skeptical after reading from a few places about how this can be a carcinogen, but the study it's taken from is massively biased and not really applicable to humans. If you're after a supplement to take at night just so your body doesn't starve itself of proteins during synthesis while you're asleep, this is what you need. A lot of people take just whey during the day which is fine, but this is making sure you are never low on protein during your whole day cycle. I recommend this 100% to everybody that is looking for high quality casein. Now, the truth about Casein itself is pretty straightforward. The study was done on mice - not humans. It's true that Casein is a slow release protein and it does sit in the colon for a while, but that's true for anything honestly. If you eat or drink late at night, it will sit in your stomach for a good 8 hours (minimum) until you wake up. There's nothing wrong with that because the body has a natural suppressive effect on its own digestive system which occurs around 2am every morning. Also, Casein is made by heating up milk into a powder. Using lower quality milk from questionable places during this process will probably come with some side-effects but this is Optimum Nutrition - as long as they keep using high-standard ingredients everything will be fine. That being said, I have only ever trusted Casein from ON themselves, I just don't see the strong track record with other brands. If you're thinking about getting this you probably should. Don't cheap out - get the good stuff.

Best casein I’ve tried so far, vanilla is definitely better than chocolate. Tastes better and is a lot smoother while chocolate has that grainy texture so I won’t buy that flavour again.. It is a bit better if I shake it with a spoon of peanut butter but if you’re thinking about buying it, I’d recommend vanilla over chocolate any day! I’m also lactose intolerant and this is so far the only casein I’m able to drink without any issue.

Can’t fault the fact that it does keep me feeling fuller for longer, as I don’t eat when I’m working (I’m a carpenter). But compared to normal whey protein this stuff is very dry tasting and a little powdery. Also it’s a super fine dust that sticks to absolutely everything if you spill it 😂 besides that it tastes good and can feel a difference

I used the ON Casein regularly in the past but had to take a rest from training for a while. Now that I am back, I am disappointed that they have changed the formula. I used to wish to use this as my only protein supplement as the taste and mixability were excellent. What we have now is simply terrible in comparison. If you have not had it before, you may think it is fine, but it used to be so much better. This stuff used almost to mix itself, but now it is full of lumps that are hard to mix without a blender. I would no longer recommend this to anyone with the new flavour and difficulty to mix. This review relates to vanilla. However, sadly, I purchased the chocolate flavour too and felt the same about it, but I had not tried this before.

The powder is fantastic. Creatine does not agree with me at all so I have upped my protein intake drastically and this product gives me exactly what i need. When you are lifting to get big and ripped anyone in the know will tell you that periods of fasting are absolutely the worst thing you can do and when do you fast for longer than when you are asleep? When taken before bed with water this product increased my raw strength and lean size drastically, not to the same extent as cycling creatine but as i've said, there are serious side effects to use of creatine if you are sensitive. If i was asked to quantify i would say that this improved my results by at least 20% and don't be put off by the price! There is no substitute for milk proteins and a combination of casein in the morning and evening and whey pre and post workout is the best you can give your muscles. You'd have to eat a tin of tuna to get the same amount of protein as you do in a serving of this and its massively inferior protein at that!

Bloody awesome idea. Some sort of satisfaction knowing that my aching muscles are being trickle-fed during time spend sleeping. But it tastes bloody horrid, and makes me sick forcing this down. Much better off blended with half a banana. It need something to distract from the taste. Also be prepared to wake up thirsty as a shipwreck survivor and gassy.... and I mean Sewage from hell scented gassy. Like I say, I really hope is doing me some benefit.

ON casein is by far and away the best casein on the market. The vanilla flavour mixed with peanut butter and bannana is superb. Ideal product for myself as i like a snack at night so use this. Im still not 100% convinced you need a casein supplement if you get your macros for the day down but if you can afford it then go for it. Good ingredient profile.

Texture imbuvable, donne envie de vomir

Tastes great and keeps me full overnight.

C'est une caséine micellaire. C'est bien ce que je cherchais. On ne sait malheureusement pas d'où viennent les matières premières, ce qui est le cas d'une bonne partie des produits de ce type. Ceci dit elle est très digeste, ce qui est un excellent point, étant donné que ce n'est pas forcément gagné d'avance. Vous verrez beaucoup de gens devenir "intolérants" aux protéines laitières, plus à mon avis qu'avec les produits dont on disposait il y a vingt ou trente ans, qui étaient pourtant théoriquement moins "high tech" (mais étaient souvent majoritairement constitués de caséines, justement et non de whey comme aujourd'hui). La cerise sur le gâteau c'est que c'est une protéine vanille avec une texture crémeuse, un goût pas trop chimique et que ça donne quelque chose de très agréable à consommer aussi bien sous une forme plutôt liquide ou sous forme de crème (avec tous les intermédiaires possibles). Elle me semble d'ailleurs meilleure sous cette forme, et c'est là qu'on est heureux qu'ON n'ait pas eu la main trop lourde sur les édulcorants. C'est mon goût, je sais que certains ont du mal avec la texture des caséines, mais j'avoue ne pas bien comprendre pourquoi. La vanille, il faut le rappeler est le parfum le plus versatile : on peut faire des milk shakes aux fruits rouges, ou à la banane, selon les goûts. Le parfum est présent mais s'efface devant à peu près tout ce qu'on peut mélanger avec. C'est pratique. Le chocolat n'est pas extraordinaire, mais reste buvable. J'ai testé un mélange avec la whey ON vanille et la caséine chocolat, c'est sympa, plus que le chocolat seul donc. Une protéine pratique, facile à consommer et peu agressive sur les intestins (en tout cas pour moi) plus que d'autres, en tout cas. On augmente bien sa consommation de protéines avec sans problème(s). Mélangeable avec une whey pour avoir une protéine "à l'ancienne" mixte après l'entraînement ou le matin. En collation avant l'entraînement (1h environ) semble aider à maintenir un bon niveau d'énergie, même au régime, plus efficace à mon sens que des BCAA pour ce genre de chose et aussi efficace qu'un mélange peptopro / maltodextrine, les calories en moins. Bonne protéine de régime donc, comme de prise de poids, sans doute. Je recommande. Bon produit à tous points de vue.

Very good quality casein protein. Mixes smoothly and has a nice thick texture, which is great for a nighttime shake. Helps keep you full and supports recovery while sleeping. Optimum Nutrition is always reliable.
