QUESTION: Mark, should I take whey protein isolate or concentrate? Is one better than the other for building muscle?
Strictly speaking, whey isolate is a superior form of protein…but it actually doesn’t matter.
It is superior in the sense that it just has more protein per serving.
WHEY ISOLATE VS WHEY CONCENTRATE
Whey isolate typically has a 90% protein content. So a 50g serving would deliver 45g protein.
Whey concentrate typically has a 75% protein content. So a 50g serving would deliver 37.5g protein.
You can get the same amount of protein simply by using more concentrate powder.
That’s why isolate is more expensive. For me personally though, the extra expense doesn’t justify the extra protein per serving.
So I buy whey concentrate and just make sure I measure it out with kitchen scales so that I’m confident about how much protein I’m actually getting.
So unless you are keeping your carbs really low (below 30g) I recommend you just stick to concentrate. A good isolate I have always recommended is Isopure (zero carb) Whey Isolate.
And you can get Impact Whey from MyProtein by using the links below. The code “MUSCLEHACK” used at checkout will knock 10% of your order – and all orders in the future.
Hope that helps,
