... Whey isolate digests FASTER than concentrate.
I'd say it is slow digesting.
I have it right beside me and it has casein in it as one of the first ingredients so yeah, it's slow digesting protein.
Whey protein isolate is the purest form of whey protein and is the fastest digesting.
If you see casein protein in the ingredients, then you'll know it is slow digesting, if you see whey protein in the ingredients, you'll know if it is fast digesting.
Remember, isolate is the purest type of protein and concentrate comes after that.
