Whey vs. Isolate

[motocrosser]

What's the biggest differences and is it enough to justify to pay more for isolate or over-rated?

You mean whey concentrate vs. whey isolate?? The difference concerns degree of bioavailability.....whey isolate is absorbed extremely quickly in relation to whey concentrate. This is why people often take isolate post-workout.....but isolate is not the best choice when you want a slower rate of digestion (e.g., at almost every other time of the day besides post-workout). Personally, I doubt it will make or break your progress.

i was thinking the same thing-

errnt!

The protein in WPC (Whey protein concentrate) and WPI (Whey protein isolate) is the exact same--whey protein. THe difference is for the isolate they do a little more in the way of filtering out the non-protein portion of milk i.e. carbs and fats.

WPC is 80% whey protein. WPI is 90% whey protein. In other words you are getting 12.5% more protein.

WPI is about 2x the price of WPC.

You do the math.

I use WPC with grea results.

WPI is only for people with money to burn or who have a reaction to the tiny amount of lactose in WPC.

On paper there are big differences.
In reality it probably equates to 0.00001% more muscle.
Having used both extensively, think there's no real difference.
Go for WPC.

Bump for the controversy

Are you saying that isolate doesn't have a higher biological value than concentrate?

In any case - I don't believe isolate is going to make or break one's physique....like you said....it's for whoever can afford it.

u want to mix... as i previously stated in another post:
Concentrates, Isolates, and even hydrolized whey have very distinct and specific nutritional benefits which supply lactoferrins, immuoglobbulins and other bioactive peptides that make them unique and both have benefits and drawbacks. Your best bet is a combination blend of the two to harness all of the benefits of the varied whey protein fractions and growth factors.

end of story.

Man you sound like a muscletech ad or something.

The type of protein-whey-is the EXACT SAME in concentrate and isolate. The difference is how much moisture, fat, and carbs are in there. In WCP, it's 20% in Isolate, it's 10. So the lactoferrins etc are there in both.

And in hydrolized whey, a lot of those immunoglobins etc. are broken down or hydrolized so they aren't active. Hydrolisis is a waste of money because your body is very efficient in hydrolizing the protein you put in your gut. Hydrolozed whey MAY get the AAis into your bloodstream a few minutes earlier but that's it.

That's exactly what I'm saying. The BV figure is for whey, whether it is at a 80% or 90% concentration.
