FAQs

How much protein is in one scoop?

Each serve has 24 g of protein. In Double Rich Chocolate a serve is 30.4 g (about one scoop) and also provides 496 kJ, 1 g of fat and 3 g of carbohydrate. Scoop weights differ a little between flavours, for example Extreme Milk Chocolate uses 32 g, but protein stays at 24 g per serve.

How many serves are in the 4.54 kg (10 lb) size?

We could not confirm the printed serve count for this size. At 30.4 g per serve, Double Rich Chocolate works out to roughly 149 serves in 4.54 kg, and flavours with larger scoops, such as Extreme Milk Chocolate at 32 g, give fewer. Check the count printed on your pack.

Is it lactose free?

No. It is labelled gluten free, but not lactose free. Whey protein isolate is the main ingredient, and the blend also includes whey protein concentrate, which the Australian Institute of Sport notes carries a small amount of lactose. It contains milk and soy, so it does not suit anyone allergic to either.

Can I mix it with milk?

Yes. The label directions allow 180 to 240 ml of cold water, milk or another drink per scoop. Milk adds its own protein, carbohydrate and kilojoules, so your shake will contain more than the panel shows, because the panel is for the powder alone. Water keeps it lighter if you are watching your energy intake.

Is it an isolate or a blend?

It is a blend led by whey protein isolate. At 79 g of protein per 100 g (Double Rich Chocolate), it sits between a typical concentrate (70 to 80% protein) and a typical isolate (about 90%), using the ranges in the AIS protein fact sheet. Our guide to whey protein isolate vs whey blend explains the trade-offs.
