Choosing a protein powder

Whey blends such as Applied Nutrition Critical Whey and Naughty Boy Advanced Whey are the everyday choice for a shake. Isolates such as BioTechUSA Iso Whey Zero and Applied Nutrition ISO-XP are filtered further, so they usually carry less lactose and fat. Clear whey mixes like a fruit squash rather than a milkshake, and casein is a slower-digesting milk protein that many people take in the evening.

You'll also find beef protein, mass gainers, cream of rice and protein bars here. If you avoid dairy, see our vegan and plant-based range. New to protein? Read Whey Protein: A Beginner's Guide.
