FAQs
How many serves are in the 3 lb tub?
Every flavour has 44 serves. Net weight runs from 1.32 kg (Rich Vanilla) to 1.41 kg (Cookies & Cream), because each flavour has a slightly different scoop size.
What other sizes are there?
We also stock the 1.5 lb tub with 24 serves and the 5 lb tub with 76 serves, both in Chocolate Bliss and Rich Vanilla. The 3 lb tub is the only size here with Cookies & Cream, Salted Caramel and Banana Cream.
How much protein is in one scoop?
Every flavour lists 25 g of protein per serve. A 31 g scoop of Chocolate Bliss is about 80% protein by weight, with 1 g of carbohydrate and 0.5 g of fat.
Is it lactose free?
It is not labelled lactose free. Isolate is filtered to leave minimal carbohydrate and fat, as the AIS protein fact sheet explains, and Chocolate Bliss has just 1 g of carbohydrate per serve. It still contains milk, so it does not suit anyone with a milk allergy.
What does hydrolysed whey mean?
Hydrolysed whey has been processed further to break proteins into shorter peptides, which is often described as pre-digested. The AIS protein fact sheet notes the practical difference between whey forms is small. Compare more options in our whey protein isolate range.
