The Problem with Liquid Collagen Protein

Your patients might ask about the difference between liquid collagen protein and

whey protein isolate. As you probably know, UNJURY uses ONLY the highest quality

whey protein isolate.

The issue -- and it is a serious issue -- with collagen protein is the quality

of the protein -- how well your body can use the protein. So first, what is

collagen protein?

American Society of Metabolic and Bariatric Surgeons warns about collagen-based

protein supplements.

Collagen protein typically comes from the skin of animals, e.g. cows, or from

other residual connective tissue that hasn't gone to other markets.

It is well understood that collagen protein alone is an incomplete protein. It

is completely lacking in trypotophan, an essential amino acid. As a result, it

has a protein quality score (PDCAAS) of zero. Protein quality scores range from

0 to 100. The ideal is 100, and the whey protein isolate in UNJURY has a PDCAAS

score of 100.

With collagen protein, even when the manufacturer adds ingredients to try to

improve the PDCAAS score, it is common for the PDCAAS score to remain low. The

American Society of Metabolic and Bariatric Surgeons nutrition white paper

states:

" Caution should be used when recommending any type of collagen- based protein

supplement. "

Consider a product called " ProGo " from Bariatric Advantage. The manufacturer

added some tryptophan, but not enough to give it a high PDCAAS score (more

below).

Bariatric Advantage has openly published levels of the individual amino acids

( " AAs " ) in the product so it is easy to calculate the PDCAAS score, but we can't

find it on the page. The individual AAs don't tell you that much. We think the

PDCAAS is the whole story.

There is always the chance that someone might conclude, well, if they show all

that amino acid information, it must be good. So using the information they

provided, we calculated that the PDCAAS of the ProGo product: the PDCAAS

calculates to 31.

In comparison, UNJURY® Protein has the highest PDCAAS possible, 100. That is

almost 3 times as much complete protein.

Surprisingly, collagen products can be quite expensive per gram of protein, and

then you need to factor in the quality of each gram of protein.

Consider the ProGo product, per 20 grams of protein, is costs between $2.99 to

$4.95 depending on what you buy2.

But their 20 grams of protein only has a PDCAAS of 36. If you converted that to

the value of 20 grams of PDCAAS = 100 protein, the price translates to $8.32 to

$13.75.

In contrast, UNJURY® Protein is about $1.11 per 20 grams of protein, and you get

get the price lower than $1.00 on autoship. And that protein has a PDCAAS of

100.
