Protein Works Whey Protein 360 vs MyProtein Impact Whey.

How the numbers stack up against the price

Protein Works Whey Protein 360 Gold and MyProtein Impact Whey Protein Powder are the two big UK direct-to-consumer whey powders, and they are built on opposite ideas. Protein Works Whey Protein 360 Gold is an all-in-one: 68g of protein per 100g, twelve added vitamins and minerals at 15% of the reference intake each, and a five-enzyme DigeZyme complex. MyProtein Impact Whey Protein Powder is a plain whey concentrate at 72g per 100g with nothing added, which is exactly why it is cheap. At their best pack sizes there is almost nothing in the headline price - 72p per 25g of protein for the 4.8kg bag of Protein Works Whey Protein 360 Gold, 75p for MyProtein Impact Whey Protein Powder.

MyProtein Impact Whey Protein Powder wins for most buyers, on what is in the tub rather than what it costs.

Protein Works Whey Protein 360 Gold carries 19g of carbohydrate per 100g against MyProtein Impact Whey Protein Powder’s 8.9g, and 16g of that 19g is sugar - MyProtein Impact Whey Protein Powder holds under a third as much. Salt is 1.4g per 100g against 0.4g. The bigger point is the protein itself: Protein Works Whey Protein 360 Gold lists soy protein isolate as the second ingredient in its blend, ahead of milk protein concentrate, in a product sold as Whey Protein 360. Ingredient lists run in descending order by weight, so that soy is doing real work. Neither product is soy free, but MyProtein Impact Whey Protein Powder’s soy is a lecithin emulsifier rather than a protein source.

Buy Protein Works Whey Protein 360 Gold if you want the vitamins, the enzymes and the flavour range in one tub and you are buying the 4.8kg bag - at 600g it is £1.04 per 25g of protein, which is 45% more than the big bag and no longer competitive with anything. Buy MyProtein Impact Whey Protein Powder if you want protein and nothing else, or if the sugar and salt matter to you. If you are drug tested, note that neither publishes a third-party batch-testing certification we could verify.
