Gold Standard 100% Casein

Gold Standard 100% Casein

Faster digesting amino acids are 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.*

While fast digesting Whey Protein Concentrates and Isolates are perfect for post-workout recovery, to feed your muscles fast, a slow digesting protein is beneficial at other times, primarily before bed, to keep your muscles fed while you rest.

Each serve of Optimum Gold Standard Casein contains 24g of Micellar Casein protein, which is protein derived from milk, best known for its properties to “gel” during the digestive process, resulting in a release of amino acids over up to 8 hours.

Low in carbohydrates, fats and sugar, and high in BCAAs, Glutamine and Glutamic Acid, Optimum Gold Standard Casein  is an ideal meal replacement, pre-bed shake or guilt-free midnight snack to keep your muscles nourished and growing while you sleep.

Available in Choc Peanut Butter, Strawberry Creme, Creamy Vanilla, Banana Cream, Chocolate Supreme and Blueberries & Cream!

Using a shaker cup is the easiest and most convenient way to mix up a consistently great casein shake every time. Just add one heaping scoop of Gold Standard 100% Casein™ to a shaker cup filled with 10-12 oz of your preferred beverage. Cover and shake for 25-30 seconds. TIP: Adjust the intensity of your Gold Standard 100% Casein™ by varying the amount of liquid that you use to prepare it. For a bolder flavour with slightly more body and sweetness, mix one heaping scoop with 8-10 oz of water, milk, or your favourite beverage. For a milder tasting, less sweet shake, use 12-14 oz of liquid per scoop.
