Collagen is an important protein that exists ubiquitously in the body. It is naturally contained in a high amount in the skin, bone, joint cartilage, blood vessel, tendons, and teeth. It occupies one- third of total body protein maintaining youthfulness, health, and beauty.
Yasin Bovin Collagen is extracted from fresh bovine skin, it,s rich in kind of amino acids and very easy to absorb. Its instant solubility makes it easy to use in the wind ranges of applications such as functional food and beverages, healthy and nutrition bar, beauty and cosmetics products, pharmacy and so on...
Collagen is a hot product in today's beauty and skincare industry, and there are numerous advertisements about it, such as this one: "to choose the collagen with the molecular weight between 1500 ~ 3000 Dalton, the collagen with the molecular weight range has the strongest activity and the best absorption effect after taking. The molecular weight of collagen in deep-sea fish is lower than 3000 Dalton. -- sounds "scientific."
Collagen is a protein widely found in mammals, especially in skin and bone. Its amino acid composition is quite different from the human body's needs, and it is regarded as an "incomplete protein", that is to say, its ability to meet the human body's protein needs alone is relatively poor.
But because it is part of the skin and is closely linked to the aging of the skin, many people want to take it as a supplement to their "skincare". But so far, there is no scientific evidence to support the claim that taking collagen improves beauty. What fashionable women believe is a myth, not a fact, preached by the beauty industry.
Collagen molecules are large, usually tough, and insoluble in water. For ease of use, hydrolysis is often required, usually by breaking it up into small pieces using a protease. When the small pieces are not very small, depending on the source of raw materials and processing technology, the formation of things like gelatin, gelatin, fish glue， and jelly. At the molecular level, they are all collagen, but of different origins and degrees of hydrolysis. When the hydrolysis is sufficient, it is often called "collagen hydrolysate", and the protein fragment is very small, which is usually called "peptide" or "peptide".
Because all proteins in the gastrointestinal tract are first broken down into a single amino acid, or at most two or three amino acid "dipeptides", "tripeptides" can be directly absorbed, so the so-called "hydrolysis" is only equivalent to the gastrointestinal work in vitro to do part of it. It can make the collagen protein in the body for digestion, absorption, a little easier, but the "ease digestion, absorption," does not mean what it means to the skin, published academic papers in only a small experiment, the results are: taking collagen hydrolysate group skin conditions, and not taking control group no real difference.
Therefore, the sentence "collagen activity in this molecular weight range is the strongest" in the advertisement is "water without source" -- collagen activity is not based on itself, how to compare which is stronger and which is weaker?
As for "the molecular weight of collagen in deep-sea fish is lower than 3000 Dalton", it is against the common sense of biology. At a molecular weight of 3,000 daltons, there are at most 20 amino acids, a number that doesn't make proteins at all. If the hydrolysis is used to change the high-molecular-weight collagen into a polypeptide with the molecular weight less than 3000 Dalton, then any collagen can be used without "choosing the deep-sea fish as much as possible".
Collagen and its various hydrolysates and powders are of the low nutritional value as proteins. There is no scientific theory and evidence to support the legendary functions of "delaying aging" and "beautifying skin". Fortunately, there is no evidence that taking collagen has any significant adverse health effects.
