ON Gold Standard Whey vs MyProtein Impact Whey

Two of our best-selling protein supplements - but which to choose?

Optimum Nutrition's Gold Standard Whey vs MyProtein Impact Whey Protein

Protein content per serving

Optimum Nutrition Gold Standard Whey: 24g (approx)
MyProtein Impact Whey Protein: 20g (approx)

The Optimum Nutrition version contains 20% more protein per serving.

Ingredients

Both Gold Standard Whey and Impact Whey are made from high-quality proteins, but each is different.

The main ingredient in Gold Standard Whey is Whey Protein Isolate - a leaner form of whey - as well as Whey Protein Concentrate and Hydrolysed Whey Protein Isolate.

On the other hand, MyProtein Impact Whey's exclusive source of protein is Whey Protein Concentrate. Both forms of whey offer very similar amounts of protein and amino acids per serving, but the isolate has had the lactose almost completely removed which reduces the calories and carbs. It also reduces the chances of bloating after drinking.

Conclusion

In summary, the comparison is more complicated than it looks.

If you're looking for the best value product (and you are not concerned by a few extra calories and the lactose), we recommend MyProtein Impact Whey.

If you're looking to minimise calorie and carb intake and the highest quality, go for the Optimum Nutrition Gold Standard Whey. If bloating or lactose is a concern, check out our range of isolate proteins, or beef protein.
