Whey isolate at the Vitamin Cottage

[Shmackey]

Anyone use this stuff? It's 9 or 10 bucks a pound (depends how much you get), pure isolate. From New Zealand. I got a small bag because I ran out of my usual and I won't get the delivery until Monday.

Thats pretty expensive.....I just got 5 lbs of Optimum 100% Whey Protein for $21.00.

That is pretty expensive. If you're specifically looking for "pure" isolate you might find better prices at www.allthewhey.com. Unless, of course your looking to specifically not buy online then I say get what you can get.

[Shmackey]

bimmerkidd, your stuff isn't isolate. So it's apples and oranges.

Allthewhey.com is a little cheaper, but there's shipping.

[Kitara]

You're right Shmackey - the shipping cost and time waiting may not outweigh the savings.

edit: Can I ask why you specifically want isolate? Just out of curiousity because I don't really quite understand the difference.

edit #2 . I went and looked up the answer myself. Here's what I found for anyone that wants to know the difference between concentrate and isolate.

So What's The Big Difference Between Whey Protein Isolate and Concentrate?

Most of the whey protein powders you find will contain mostly whey protein concentrate with some whey protein isolate mixed in. You'll also find a lot of pure whey protein concentrate, and some whey protein isolate. Comparing the two, whey protein isolate is more expensive than concentrate - because it's of higher quality(more pure), and have a higher biological value (BV). Whey protein isolate contains more protein with less fat and lactose per serving. Usually, isolate contains 90-98% protein while whey concentrate contains 70-85%.

Whey protein isolate is the highest yield of protein currently available, and it comes from milk. Because of its chemical properties, whey protein is the easiest to absorb into your muscles. Obviously, with its high concentration, whey protein isolate 'would' be the best to use, but like all great things, there's always a downside. It's more expensive, and just because it's more pure, doesn't mean it'll give you more muscle and size. Its extra concentration may not justify the extra costs for you.

Whey Protein Isolate Interesting Findings

On a positive note, studies have shown whey protein isolate to have immune boosting properties. Check this out, I bet you didn't know this:

"The results of the study demonstrate that hydrolyzed whey protein isolate can significantly increase glutathione levels within the prostate epithelium. This represents a potential mechanism by which whey protein isolate can provide protection against the development of prostate cancer." - Dept. of Food Science & Technology, Ohio State Univ.

To Use Whey Protein Concentrate or Whey Isolate?

So when all's said and done, should you use whey protein isolate, or concentrate? On the plus side, whey protein isolate is more pure, but it also costs more. Most protein powders you find will have mostly whey protein concentrate with some isolate blended in.

In my opinion, I don't think its worth the extra bucks to use pure whey protein isolate. Using whey protein concentrate with isolate blended delivers just as good results with less costs. You'll also hear from other bodybuilders that they don't notice whey protein isolate giving them any noticeable amount of gains over whey concentrate, so I say go for the less pricey blend of the two.

Note: if you're lactose intolerant, whey protein isolate maybe a better chioce since it contains less lactose.

My question to you all is why are you using stuff?

[Shmackey]

Kitara, I'm just using it until my normal shipment of Designer Whey (I get it cheap) comes in. I ran out.

Eagan, you don't know why people drink protein shakes?

[Eagan]

My question Why do people drink this stuff. I would and do make shakes with vegetable or fruit, I don't
use milk as it will put weight on you very quickly. You can get all your vits and minerals from food. Raw is the best. Most of these products have fillers
baking powder or starch etc. They aren't listed on the label you might want to ask a medical professional chemist about the products. A sales person in a health food store or sports store is there
to sell a product. Research Research as it is your body and you are the god of it. One dosen't take medications given by a doctor without asking lost of questions. Food for thought.

[Kitara]

Just a side comment: Protein powder doesn't have anything to do with vitamins and minerals. It's protein, period.

[Shmackey]

Exactly. If you get enough protein from your blended-up raw veggies, hey, go nuts.

Whey isolate contains no lactose and tends to digest easier than concentrate with no bloat. Though you can use whey concentrate between meals for extra protein, I believe that you should stick with whey isolate only for post-workout recovery or rather the hour window.
