Hydrolyzed Whey Protein Isolate same as Whey Protein Hydrolysate?

topic

Hydrolized means it's been broken down.

You can hydrolize isolate or concentrate. So the answer is maybe. What brand are you seeing just the "Whey Protein Hydrolysate" label?

It might not be since hydrolyzed whey protein concentrate exists as well.

I mean if they were both isolate which is better hydrosylate (is that combination of isolate and hyrolyzed? so there is no whey concentrate hydrosylate?) or hydrolyzed?

basically is hydrolysate just hydrolyzed whey protein isolate? so you get hydrolysate from hydrolyzed and isolate?

There are different grades of WPH. If you are interested in WPH then you should look for a grade of any where from 15-20% hydrolyzed. AST's WPH is only around 4% Hydrolyzed of a 100% WPI formula. You have to call and ask them to get this info. That is why it tastes so good. Anything-above 25% hydrolysis tastes like vomit and smells like ammonia. As far as I know no one makes a 100% hydrolyzed WPH. However there is one company that makes a high percentage WPH, but it is around 45-50 dollars a pound unflavored. I personally use a 20% WPH and can actually feel the speed of absorption. However I need to take it with carbs or else my blood sugar drops below 80 after 30 minuets of ingesting the product. WPH is the fastest absorbing form of the Whey family [1]. It delivers the full amino acid profile in 80 minutes and is the least allergenic form of whey protein, as it has already gone through an enzyme bath and is partially pre-digested. WPH also contains virtually no fat, lactose, and cholesterol.

You might find the following study interesting in that the researchers used experienced male bodybuilders and not college freshmen who like to collect stamps:

The International Journal of Sports Nutrition and Exercise Metabolism, examined the effects of supplementation with different proteins, namely hydrolyzed whey protein and casein, on muscle strength and body composition during a 10 week, supervised resistance training program Importantly, this study was conducted on experienced male bodybuilders. In a double-blind protocol, these guys supplemented their normal diet with either whey hydrolysate or casein (1.5 grams per kilogram of body mass/day). What happened? Well, this well-controlled study indicated that:

1. The whey hydrolysate group achieved a significantly greater gain in lean body mass than the casein group (5.0 vs. 0.8 kilograms). Also, the whey hydrolysate group lost significantly body fat while the casein group gained body fat (-1.5 vs. +0.2 kilograms).

2. The whey hydrolysate group also achieved significantly greater improvements in muscle strength (measured by barbell bench press, squat and cable pull-down) compared to the casein group in each assessment of strength. Furthermore, when the strength changes were expressed relative to body weight, the whey group still achieved significantly greater improvements in strength compared to the casein group.

In conclusion, it is becoming increasingly clear that high-quality whey protein hydrolysate is the best source of protein for serious strengh-power athletes. The lean body mass gains observed in the whey hydrolysate group of 5 KILOGRAMS is truly nothing short of phenomenal in a trained athlete. Indeed, the superiority of whey protein hydrolysate may have something to do with its insulin boosting actions and its extremely rapid absorption and uptake.2 Interestingly enough, this study also demonstrated whey hydrolysate ingestion promoted fat loss; high-quality whey has ACE-inhibitory activy, which leads to inhibition of storage fat synthesis in fat tissue. This new research clearly helps to shed some light on why athletes using WPH products are achieving such rapid and significant muscle growth.

Bellow is a small amount of information from David L. Barr on WPH.

"Back when it first came out, whey protein was pretty kick ass because it was discovered to be very high quality. Then research came out that made it even more kick ass, because we could classify it as a "fast" digesting protein compared to casein (Boirie et al., 1997).

You know what. This research stands today, because compared to casein, whey protein really is fast! Then again, a tortoise is also fast compared to a snail, but that doesn't mean we want to take a tortoise to a greyhound park. In other words, we've been considering whey a "fast" protein only because we've been comparing it to something incredibly slow. When we compare the digestibility of whey to the gold standard of amino acids, on which we base nearly all of our post workout nutritional data, whey flat out sucks.

This is incredibly frustrating because all of the ways to maximize protein synthesis we've been discussing have used amino acids. So we need to either use pure amino acids or use something that closely resembles their absorptive properties. This is where whey protein hydrolysate comes in. The protein is already broken up into large peptides, so we get a rapid absorption with peak levels reaching the blood at around 80 minutes (Calbet and MacLean, 2002), compared to 60 minutes for pharmaceutical grade amino acids (Borsheim et al., 2002).

Unfortunately, even the highly touted whey isolate is completely useless for our timing purposes here, because it just takes too long to get taken up by the gut (Dangin et al., 2002).

In light of these data and the growing body of literature contradicting the versatility and usefulness of whey protein, it should henceforth be classified as "moderate" or "intermediate" speed protein, with only whey hydrolysate and amino acids existing as truly "fast."

It may be difficult to adjust our thinking, but this is simply more dogma that needs to be destroyed in order to bring us up to date with the proper application of research.

The main competitor for the title of best protein is whey isolate, but after reading the following you'll see that it comes in a distant second to hydrolysate. Although you wouldn't have to worry about a catabolic decline in blood aminos with whey isolate, it has its own problems.

Even though it used to be considered very high quality, whey isolate takes more than two full hours to elevate blood amino acid levels so that they reach desired levels (Dangin et al., 2002). Having an absorption time one third longer than hydrolysate, whey isolate will give a smaller peak in amino acid levels and reduced protein synthesis stimulation as shown in Figure 2. In other words, we can have a peak twice as high or one that lasts twice as long for a given quantity of protein ingestion, but we can't have it both ways.

It's been shown that consuming amino acids in two separate doses after a workout will give two distinct but equally high spikes in protein synthesis (Borsheim et al., 2002). Either a pre or post-workout serving of WPH followed by another 80 minutes later should give the desired doubling effect. This concept is illustrated in Figure 3 with whey hydrolysate consumption.

Figure 3. Extrapolated protein synthesis levels following consumption of whey hydrolysate at time 0 and again 80 minutes later.*

Again, trying this with whey isolate is useless, because it just doesn't have the optimal absorption qualities we need.

Here's another valuable tip: the post-workout nutrient window for muscle protein synthesis will last at least 24 hours (Tipton et al., 2003), so another serving when you're fasted (i.e. the first meal of the day) will most likely elicit the same exaggerated effect of stimulating protein synthesis!"

I wrote that slick and Yes I can quote sources :)

Great pots but what I am asking is if Hydrolyzed Whey Isolate is the same thing as Whey Hydrolysate.

[QUOTE=wtfmate08;152756681]Great pots but what I am asking is if Hydrolyzed Whey Isolate is the same thing as Whey Hydrolysate.[/QUOTE]

They appear to be the same. I guess the naming convention depends on the brand you are buying from.

GTFO now jerk off. Hes trying to teach people something and your gonna **** around over who wrote it? He quoted his source. He gave those people a cite, **** off. Go back to the teen section where everyone hates you and ur e-stats. Someone may have learned something in that post. *******.
