I also want to mention that unjury recently sent me an e-mail about a new product of theirs. They are now making those concentrated test tube things as well. I have not tried them, but they might be good. Here's what they sent me (it's sort of long). They claim that the body can absorb much more of the protein with their product. Like I say, I have not tried it:
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 PDCAAS
2, 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
(
Covance: the CRO for Drug Development Services ) 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.

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. 5 More detailed results in Appendix A UNJURY® Protein 1 800 517 5111 Nutrition@UNJURY.com 6 Recommended Dietary Allowances, the Institute of Medicine of The National Academies, in the book, Dietary Reference Intakes, ISBN 0-309-08537-3

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 Appendix C. PROTEIN COMPOSITION: UNJURY, PROFECT AND NEW-WHEY

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.
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.
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.

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 UNJURY® Protein 1 800 517 5111 Nutrition@UNJURY.com Welcome to the UNJURY Homepage 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.
trying to get all in order . Sorry I know the post is here some where just cant find it.
