Product Information


If you’ve tried Gold Standard Whey, you’ll love 100% Whey Casein! Casein gives a slower release of protein than standard whey protein, making this a great pre-bed drink. Each serving contains 24g of protein, 3g of carbohydrates and 0.5g of fat. A helpful 9g dose of amino acids also make an appearance.


Slowly absorbed by the body, great for pre-bedtime fuel.

Low in fat.

Who should use?

Those looking to put on lean muscle and size.

Those looking for a pre-bedtime protein boost.


Micellar Casein [contains Emulsifier (Soya Lecithin)], Flavour, Salt, Thickeners (Cellulose Gum, Carageenan Gum, Guar Gum), Masking Agent (contains Dextrin, Flavourings), Sweetener (Sucralose, Acesulfame Potassium), Colour (Curcumin), Enzyme Complex (Amylase, Protease, Cellulase, Beta-D-Galactosidase, Lipase).
