How we test the best whey protein powders

Registered nutritionist (AFN) and sports nutritionist (SENr) Rob Hobson only tested chocolate-flavored powders to provide consistency in his reviews. He judged them on their taste, texture, solubility and nutritional effectiveness, as well as cost per serving and availability. He also took into account the variety of flavors and any recyclable packaging.

Sizes range from 300g to 4.54kg
Protein per serving:24g
Cost per serving:£1.18
Sizes:300g / 310g / 450g / 465g / 896g / 908g / 2.27kg / 4.54kg
Flavors:12 flavors plus unflavored versions available

Gold Standard 100% Whey Protein in use

This powder is low in fat and sugar and uses sucralose and acesulfame K to sweeten. This is another powder that we found a little too sweet, but each variety does have a pleasantly rich flavor.

Ingredients are minimal but it does contains soy and artificial flavors, which may not appeal to people looking for something less synthetic.

A serving of the shake contains 116 calories when mixed with water, and just 0.7g sugars, 1.4g fat and 1.3g carbs. The powder combines well but we found it slightly thin for our tastes when mixed with water.

Wide range of sizes

The tubs are available in plenty of different sizes, ranging from 300g to 4.54kg. They’re good value for money for anyone who takes shakes regularly, working out about £1 per serving for the 896g tub and even cheaper for the 2.27kg and 4.54kg options. You can pick up Optimum Nutrition shakes online and in health food stores. Packaging for both tub and pouch versions is 100% recyclable.

If you find one version a little too sweet, you’ll probably find another one that isn’t. As well as an unflavored version, there are 12 different flavors in all – ranging from banana cream and caramel toffee fudge to chocolate peanut butter and white chocolate raspberry.
