I came across a website by a Dr. Mercola and was reading an article he wrote about Glutathione where he mentioned that if one is to take whey to help increase Glutathione levels, one should use whey concentrate. He says: "Avoid whey isolates like the plague as they are loaded with putrid proteins. Most whey proteins are isolates."Anyone else heard anything about this? I always thought isolates are the best type of protein, hence their cost, now he is saying the cheaper concentrates are superior?
Yep, BulletproofExec.com is saying the same thing…
They both say it because concentrate is less processed and a good quality concentrate is often easier on digestion. What you are using will depend on your goals and your current macros.

Are they saying that because it is less processed or because they both happen to sell or be affiliated with WPC products?

Ba-zing!
They sell concentrate because they use it themselves and believe it to be better than isolate. If they thought isolate was better, they would be selling that.

I agree with Fairy on this, to the extent that from what I've read contrary to what I have believed up to this point, is that it does seem WPC is of higher quality, but contains less protein by weight. It seems the Isolates are preferred in BB community, because 1) they have more protein by weigh per serving, and 2) have virtually no lactose, so it would be easier to digest.Now aside from that, my biggest reason for posting the article is claim that WPI is filled with rotted proteins. That is what really caught my attention.I've also heard from a few other top level Powerlifters that I train with they only use WPI if they are dieting down, but use WPC if they just need a little protein bump.
Seeing as how Dave recommend isolate for a while I doubt that the fact they sell it is the only reason.
Were there any citations linked, preferably peer reviewed? Did they have any evidence other than links to their own articles or products? Did they even bother to specify a specific isolate production process? The onus is on them to prove their claims. Given that they're using decidedly scientific terms like 'putrid', I'm not going to hold my breath.
Basically what Dave says is that the stuff they take out of concentrate to make isolate is good for you, helps the protein digest better, increases glutathione and improves your immune system. He also says it is better for those with dairy allergies (who may not even know that they have one) and he also avoids Casein like many other “natural health” people. The biggest problem here is that you need to be sure how much protein is actually in the concentrate as some companies will try and get away with making that percentage very low. Personally I think how quick the protein digests after a workout is overrated and not worth the extra cost in the long run. Adding some leucine to my WPC, Creatine + Dextrose works fine for me.

What "good stuff" is removed? Specifics would be nice.Define "better digestion" and how concentrate would be superior in that regard.What in WPC improves immune function that is not present in isolate specifically? Any studies to indicate that the removal results in statistically significant immune system degradation? What particularly compound makes whey protein concentrate less allergenic? The dominant allergen in whey protein is beta lactoglobulin, regardless of whether it is concentrate or isolate. People need to really question what these guys are saying for one major reason - whey isolate prices have increased over the past few years at a rate much higher than whey protein concentrate. This has squeezed the margins of product lines using whey isolate and has likely forced supplement companies to increase their use of concentrate. There is a much larger financial incentive to promote concentrate over isolate than there was only a few years ago.

Same here.
Not to ruin anyone's dreams here, but I would need to see some more studies on the superiority of isolate vs. concentrate or other whey (sorry, couldn't resist) round. If you're a bikini competitor at 120lbs 2 weeks out, ok, but for the "normal" forum user, male, 160-200lbs @ 12-30% bodyfat, I doubt it makes ANY difference.
It's more about the potential inflammatory response that can stress your body and prevent fat burning.
