Product Description

Product Description

Optimum Nutrition's Gold Standard 100% Casein was the industry's first all-micellar Casein product. It contains 24 grams of pure casein protein per serving, with only 0.5 grams of fat. It only contains 3 grams of carbohydrate per serving, of which only 1.5 grams is sugar. Optimum Nutrition's Gold Standard 10% Casein mixes easily and is a tasty protein powder. It is best taken at night, as this is when the majority of muscle rebuilding takes place. To make your shake, simply add one rounded scoop to 300-360 ml of water, milk or your favourite drink half an hour before bed.

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.

5.0 out of 5 stars Amazing flavour 17 July 2013
Flavour Name:Chocolate| Size Name:1.8kg|Verified Purchase
I gave this product 5 stars because of the flavour of the product. It actually tastes better than some milkshakes out there. It's so easy to mix. Taste so good with milk but also tastes really nice with water.

I take this before bed and it seems to work.

Shout out to the delivery team on this. I got it on the cheap for about 32 for a big tub. I also got it delivered to my house a couple of days before it was supposed to. Top marks for everything!

5.0 out of 5 stars Nice and light before bed 25 Aug 2013
Flavour Name:banana| Size Name:1.8kg|Verified Purchase
I use it before bed to keep the hunger away during the night, the flavours aren't the best so far though, I have tried chocolate and banana both drinkable but not as nice as the whey.

5.0 out of 5 stars Midnight Snack! 24 Aug 2013
By JAW
Flavour Name:banana| Size Name:1.8kg|Verified Purchase
Due to the protein and carbs mix, I use this just before I go to bed. I mix this casein with water and milk which turns it into a banana milkshake of sorts; lovely stuff!!

5.0 out of 5 stars Always the best 1 Nov 2013
By Spike
Flavour Name:Chocolate| Size Name:1.8kg|Verified Purchase
Not a lot to be said about ON supplements - Always the best re taste and mixing
Casein is a great shake before bed , whether on its own, or mixed with some greek yoghurt or drop and egg in mix a batter and create some great protein pancakes as a healthy pre-bed snack - Casein will prevent any muscle loss through the 8-10 hours you are not eating while asleep - Amazon constantly has the best price for ON Supplements

5.0 out of 5 stars Never bothered with anything else :) 10 April 2014
Flavour Name:Vanilla| Size Name:908g|Verified Purchase
Great packaging, great results from the product! The taste is wonderful in this, the vanilla tastes like vanilla but kind of punchy and thick which brings out that flavour even more and I love that. On a muscle building point of view, this is a great product, every night I have it, I wake up the next day in a lot less pain or no pain at all. The vitamins and minerals in it are a great addition and the macro-nutrients from it including the caloric value are just perfect for me. Although I get a little bloated when I have it, I'm completely back to my normal stomach in the morning so no issues there as I can't tell when I'm sleeping. This is definitely must have product and especially this flavour over the rest. I've tried the other flavours and few other brands and till now this has been the best overall for price and results.

3.0 out of 5 stars Average Taste
Very chocolately tasting, but not the best. Also has a weird foamy chalky texture. Better to get a unflavoured powder and then mix in your own cocoa powder.
