Source: Official Journal of the European Union - COMMISSION REGULATION (EU) No 432/2012 Indications Casein proteins are pH sensitive and gel in the acidic environment of the stomach. As a result, it can take more than twice as long for caseins to be broken-down into their amino acid subcomponents than whey and other protein sources. Because of their unique time-released traits, caseins are aptly described as anti-catabolic or muscle-protecting proteins. Casein protein is ideal for use in between meals and before bed. Casein protein is sometimes known as "night time protein" because it's ideal to have just before you go to bed.

Review: Good value and mixes well - 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.
Review: I recommend this 100% to everybody that is looking for high quality casein. - 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.

### ⭐⭐⭐⭐⭐ Amazing!
*by J***Y on 26 July 2022*

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.
