New Whey IDS vials...Collegen protein?
Ok I want to add a protein suppliment to my diet. Whey protein doesn't agree with me, I tried it preop and it made me so gassy I thought I was having a heart attack, and while I have had it post op (in the form of protein bars), it tends to still make me gassy...but the other way...if you know what i mean..lol.
I like soy, but the issue with soy is 1) it's not absorbed as easily as whey, and 2) it promotes higher estrogene levels...something I want to avoid because I'm trying to gain muscle mass.
I'd use an egg protein shake, but I've developed an intollerance to eggs...and I've never found an egg protein shake that tastes good....sorry Jay Rob your egg shakes taste like crap in a cup.
I've tried the IDS 42 grams of protein vials...and they don't make me gassy at all and I actually like the taste of them (vitamin shoppe sells them in their stores if anyone wants to find a "local" vendor).
But here's the thing, Unjury (who likes to test all their comptetors products) put out a news letter a couple of months ago about how these protein vials were a waste of money, and how they are almost 95 percent collegen protein, which is unusable by our bodies. Is this true? I've seen marketing in body building magazines which state the total opposite .
does anyone know the truth? Dx do you have any rain man info on this? lol....
Anyway thanks for your help.

UNJURY® Update May 2007
Dear UNJURY Customer:
Subject: Liquid Proteins in Test Tubes: Mostly Collagen, Very Low Protein Scores1
You know Pepsi says it tastes better than Coke, and that AT&T/Cingular drops fewer calls than
Verizon. Today, we’re going to compare something more important to your health, the protein
nutrition value of several protein brands.
Different types of protein –from whey, soy, egg or collagen – provide very different nutrition value
to your body. About 4 years ago, the Institute of Medicine of The National Academies proposed a
scoring system to assign a nutritional value to different proteins. It is called PDCAAS2, but rather
than use so many initials, we’re just going to just say "Protein Score". Just like a history test in
school, the Protein Score goes from 0 to 100. You can calculate the Protein Score of a protein supplement if you know the amino acid profile of the supplement, or if you know what kind of proteins are in it, and how much. This update looks
at two protein supplement brands, "Profect"3 and "New-Whey"3 that come in "test tubes".
(Some people call them "bullets" or "shooters".)
Both of these are made mostly with collagen protein, and collagen protein alone
gets a 0 (zero) Protein Score…out of 100. But their labels
say they also contain two high scoring proteins, whey and casein, and that would affect their Protein Score. So we wanted to know how much whey and casein they contain,
and we thought you might want to know too…but we couldn’t find any information about that on their websites nor on their labels (except for the order of ingredients – hydrolyzed collagen protein is listed first). So we sent a sample of each – Profect and New-Whey –
to a respected independent laboratory, Covance, Inc.4
( www.covance.com ) for analysis. We had each analyzed
for their amino acid content – so we could calculate a Protein Score for each brand. We calculated the Protein Scores – using the IOM formula – and composition estimates on those results. (see Appendix A)
Results 5 :
1. The Protein Score for Profect is 6, and the Protein Score for New-Whey is 4, each out of a possible 100.
For details on the calculations, see Appendix C.
1 We are using the PDCAAS method of scoring proposed by the
Institute of Medicine of The National Academies in the book, Dietary Reference Intakes, ISBN 0-309-08537-3.

4 About Covance: Covance routinely conducts testing for government agencies such as USDA and
FDA and is sometimes chosen by the FDA to develop official testing methods themselves.

2. The estimated composition of the protein in Profect and New-Whey: both brands are
estimated to be at least 95% collagen protein. For details on the calculations, see

3. So how much Profect or New-Whey would a person need to consume to meet the
Recommended Dietary Allowances6 (RDAs) for all Essential Amino Acids (EAAs)?
The RDAs are based on body weight. So, for example, a 200 pound adult
would need to consume about 40 servings -- almost a gallon7 per day of
Profect or New-Whey (if these were the only protein source), to meet the RDAs for all Essential Amino Acids. In contrast, only 3.6 servings
of UNJURY are required to meet the same RDAs.
So even though Profect or New-Whey contains
25 or 42 grams of protein per serving, its low
scoring protein does not provide you all same
benefits as a protein with a high Protein Score.
Profect or
New-Whey needed
per day
Note:
It might be possible – but complicated and difficult – for a person to combine very specific
foods to help offset some of the Protein Score (EAA) deficiencies in Profect or New-Whey.
To do this consistently, a person would need to: a) know the EAA composition of the
foods, and b) know how each and every EAA "insufficiency" in a supplement is remedied
by an "oversufficiency" of each of same EAAs in the foods. Such foods would have to be
consumed within a short time of consuming the low Protein Score supplement. For more,
see Appendix B.
6 Recommended Dietary Allowances, the Institute of Medicine of The National Academies, in the book, Dietary
Reference Intakes, ISBN 0-309-08537-3
7 A 200 pound person would need to consume approximately 1 gallon; the requirements for other body weights are
proportional. For example, a 300 pound person would need to consume approximately 1.5 gallons.

Appendix B
A note on the difficulty of combining of two low-scoring proteins to try to create a high-scoring
protein combination:
It is possible for a person to do this, but it is complex – that is, it would likely require detailed
knowledge about the amino acid composition of foods, along with careful attention, for the
reasons below:
The Institute of Medicine referenced those EAAs which are " most likely limiting amino acids (see Glossary
below) in common food protein sources."8 These included the sulfur amino acids - methionine +
cysteine, and tryptophan).
In Profect and New-Whey: tryptophan is also the limiting EAA and the combination of methionine +
cysteine is also relatively low among EAAs, based on the RDAs. So consistently achieving a complementary combination would be unlikely without detailed knowledge of, and attention to, the EAA composition of the foods needed to complement

Appendix C - Calculations
Details on the PDCAAS calculations: The limiting amino acid for both of those brands (see
Glossary) is tryptophan. For Profect: 0.35 mg tryptophan / 7mg for the IOM reference protein1 x
100% for digestibility (the actual Profect digestibility score might well be lower-- in the mid 90s, but we don’t have
the exact score so we assumed 100, the highest digestibility. Because of the low overall score, the exact digestibility isn’t material.) yields a PDCAAS of 5, and we showed 6 in the chart to over-account for any possible
minor rounding effects. For New-Whey: 0.24 mg tryptophan, yields a corresponding 3.4%, which we similarly rounded to 4%. For UNJURY: 18 mg Histidine and a digestibility score of 99, the established score for whey protein yields a 100.
Details on the composition estimate calculations: Typically, whey protein and casein protein
contain approximately 16 mg Tryptophan per gram of protein or more. Collagen contains no Tryptophan. Because Profect contains, according to the Covance analysis, 0.35 mg Tryptophan per g of protein, we can estimate the percentage of whey and casein (combined) as 0.35/16.0 = 2.2%. There are possible errors in this calculation in both directions: a) there is little Tryptophan in the product so the chance for a small error exists. b) we assumed 10 mg of Tryptophan per 100 g of finished product, even though the actual lab result is: "<10" mg (that is, less than 10 mg)
of Tryptophan per 100 g of finished product. The "<10" mg result is the case for both the Profect
and New-Whey samples. To avoid overstating the percentage of protein from collagen, an incomplete protein, we simply used 95%.
Glossary
Amino Acid ("AA")
Amino acids are the basic building blocks of protein. There are 20 different amino acids in the
human body.
Essential Amino Acid ("EAA")
Of the 20 amino acids, 9 are called "Essential" (or "Indispensable") because they cannot be
synthesized, or manufactured, by the human body. They must be supplied in the diet. If an
insufficient amount of any one EAA is consumed over a long enough period of time, symptoms of
protein deficiency will develop.
Limiting Amino Acid
This is the EAA which is present in the least amount, relative to the requirements. As noted in the
IOM book, "…the ‘limiting amino acid’ will determine the nutritional value of the …protein in the
diet." The net protein utilization is profoundly affected by the limiting amino acid content.
I received the newsletter too and I really don't know what to think of it. It makes perfect sense to me that if a protein doesn't contain the full spectrum of different branch-chain amino acids that one that does would be more "valuable" to our bodies, but again the fact that it is coming from a source that is not neutral makes me weary. I don't really know what to tell you other then that I haven't bought anymore of them and have been sticking to the whey protein powders that I already have in mass quantities in my pantry for when I occasionally feel the need to supplement. I'm fortunate though in that by body tolerates them just fine. We may have to wait for Dx to get back from his business trip to get a good in-house answer on this from The Professor, but in the meantime, I will try to remember to ask my clinic nutritionist about this when I see him at my 3 month post-op appointment next thursday.

Hi, I've read about this report for months and I've had a bunch of ??? regarding how valid they are from another supplier... All I know is that I've been using the New Whey vials for now 9 months and have never had a problem nor am I protein difficient. by the way I mix half a tube at a time with 16 oz. of Crystal Light.
