Sometimes slower is better - especially when it comes to the rate of protein digestion. While rapid protein absorption is desirable immediately before or after exercise, delayed release is probably more beneficial throughout the remainder of the day; Optimum Nutrition's Casein is the ideal slow release protein to add to your supplement stack

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 proteins. Because of their unique time-released qualities, caseins are aptly described as anti-catabolic or muscle-protecting proteins.


SLOW-DIGESTING PROTEIN

Faster digesting protein is desirable immediately before and after exercise to help refuel recovering muscles, but slow digestion and absorption may be more beneficial at other times including bedtime when your body typically goes for hours without food. Casein products are acid sensitive and thicken in the stomach. Compared to some other proteins, it can take longer for our Gold Standard 100% Casein™ to be broken down into its amino acid subcomponents. By using only premium micellar casein as a protein source, Optimum have created a formula that sets the standard for slow digesting protein support.

    • What is the benefit of slow-release protein like Optimum Nutrition's Casein?

      Slow-release protein, such as Optimum Nutrition's Casein, offers a gradual and sustained release of amino acids into the bloodstream. This slow digestion and absorption rate make it ideal for times when rapid protein absorption is not necessary, such as between meals or before bedtime.

    • How does casein protein differ from other types of protein in terms of digestion?

      Casein proteins are pH-sensitive and form a gel-like substance in the acidic environment of the stomach. This unique property results in a slower digestion process compared to whey and other proteins, allowing for a prolonged release of amino acids into the bloodstream.

    • What makes casein protein suitable for bedtime consumption?

      Consuming casein protein before bedtime provides a steady supply of amino acids to muscles throughout the night when the body typically goes for hours without food. This helps prevent muscle breakdown and promotes muscle recovery and growth during periods of fasting.

    • How does Optimum Nutrition's Gold Standard 100% Casein™ stand out from other casein products?

      Optimum Nutrition's Gold Standard 100% Casein™ utilizes premium micellar casein as its protein source, setting a standard for slow-digesting protein support. This ensures a high-quality product that delivers the benefits of slow-release protein effectively.

    • When is it most beneficial to consume casein protein?

      Casein protein is most beneficial when consumed during periods of prolonged fasting or when rapid protein absorption is not required, such as between meals or before bedtime. It provides a sustained release of amino acids, supporting muscle recovery and preventing muscle breakdown.

    • How does slow-digesting protein like casein help protect muscles?

      Slow-digesting proteins like casein are described as anti-catabolic because they help prevent muscle breakdown by providing a continuous supply of amino acids to muscles. This muscle-protecting effect is especially valuable during periods of fasting or extended periods without food.

    • Can casein protein be used in conjunction with other protein supplements?

      Yes, casein protein can be used alongside other protein supplements, such as whey protein, to provide a combination of fast- and slow-release proteins for optimal muscle support throughout the day.

    • Is there a recommended dosage or timing for consuming Optimum Nutrition's Casein?

      Optimum Nutrition recommends consuming Gold Standard 100% Casein™ between meals, before bedtime, or any other time when a slow-digesting protein source is desired. Follow the serving size instructions provided on the product packaging for optimal results.

    • Can I use this while taking Elemental Nutrition HGH?

      Yes, you can take it whilst taking Optimum Gold's Standard Casein.

    • Hi there I've read that your product should be fine for people with lactose issues, do you have sample packs or smaller sizes please so I can test this out prior to buying a massive tub? Hoping this will be the cherry on my boulder shoulder building cake :)

      Our samples normally depend on what we get given by the supplier and Optimum Nutrition doesn't offer any sample sizes at this stage.

    It's hard to go wrong with ON protein products. This casein protein does exactly as advertised; it mixes slightly thicker than a WPI or concentrate and stops me from waking up ravenous in the mornings. Chocolate Peanut butter flavour is delicious.

    Good product, good taste. Sweet, but not too sweet, but you need to add more liquid because it gets very thick standard liquid amount. Over all, solid product, very useful last thing at night.

    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. Minus the guilt.

    I also add it to coffee sometimes to create a super-creamy latte type drink without the calories.

    It's obscene how delicious this is. A bit like an Oreo McFlurry crossed with a thick shake. And amazing that it has pretty much no carbs or fat, and keeps me full for hours. Really helps with the weight loss goals. You guys know what you are doing :)

    Delicious and creamy protein powder. Blends well into a thick creamy mousse if you use less water, or a thick shake consistency with more water that also tastes great. Loved the peanut and chocolate flavor, I’ve bought this and 2 other Optimum Nutrition casein protein flavors from Mr Supplement because I was so impressed with this protein brand, and Me Supplement has had the best price on this protein for a while now so I don’t shop for it anywhere else.

    Delicious protein, I like how the casein makes it thick and creamy. Barely any sugar and yet it still tastes sweet. Makes a good pudding/mousse I’d you use less milk or water.
