FAQs
How many serves are in the 15 and 30 serve sizes?
The 15 serve pack holds 2.24 kg (about 5 lb) and the 30 serve bag holds 4.47 kg (about 10 lb), based on a 149 g serve of two heaped scoops. Scoop weights can vary slightly between flavours.
Can I have half a serve?
The label serve is two scoops (149 g). Using one scoop simply halves the numbers, giving roughly 280 Calories and 15 g of protein, which can suit people who want a smaller top-up between meals. Adjust to fit your daily energy needs.
What sweeteners does it use?
The Chocolate Fudge label lists sucralose and stevia leaf extract. It also has 9 g of total sugars per serve, of which 4 g are added sugars, with the rest coming from ingredients such as milk proteins and fruit powder.
How much protein do I need each day?
The NIH Office of Dietary Supplements cites 1.2 to 2.0 g of protein per kg of body weight a day for athletes. One serve of Clean Gainer gives 30 g, so it can make up part of that alongside regular meals.
