Ordinary collagen is proteins of large molecules, and the molecular weight is above 300,000 Dalton, so it can't be directly absorbed by the human body. Food containing collagen must be decomposed into simple small molecular amino acids by the proteases in the digestive tract, and then they can be absorbed in the intestinal tract. After a complex biochemical reaction within the body, collagen needed by the human body will be synthesized, and provided to meet the need of the tissues and organs. So we can say the proclamation that eating pig skin or taking macromolecular collagen protein can beautify and moisturize the skin, and that they have anti-aging effect definitely are not grounded in medical theory.On the contrary, tripeptide collagen can be directly absorbed by the human body and join the systemic circulation directly without the needing decomposition of stomach digestive enzymes inside the intestines.
Tripeptide collagen has a triple-helical spiral structure, and it is acid-alkali resistant, heat-resistant, low volatility, and can be completely absorbed by the human body. When applied to skin, the tripeptide collagen can make the skin moist, tight and elastic. In order to make the skin delicate, moist, tight and elastic, people should take in collagen peptide but not collagen. Strictly speaking, it is the tripeptide collagen that needs to be taken, which is different. According to present studies, tripeptide can be fully absorbed.We can identify the peptide by the range of its molecular weight:
1 The molecular weight of small peptide (oligopeptide, active peptide) is below 1,000D, composed by three amino acids , and it can be directly absorbed and used by the dermal layer, but in the process of absorption, because of its small molecular weight, the structure is not stable, and can easily to decompose naturally.
2 The molecular weight of polypeptide is between 1,000D and 3,000D, and the polypeptide is composed of 5～6 amino acids. After entering the human body, the polypeptide will synthesize the protein or collagen into different parts of the body, beautifying the skin while effectively supplementing the loss of the body's collagen.
3 The range of molecular weight of large peptide is between 3,000D and 5,000D. Large peptide is composed of 100 ~ 1000 amino acids, and the utilization rate is limited.
Compared with polypeptide, the value of large peptide is different and much lower. Polypeptide is more expensive than gold while large peptide is very cheap. As polypeptide has 10 times more physiological functions than large peptide, and has a very storng activity and diversity, as well as important biological functions, it is thus called active peptide. With purely natural raw materials, active polypeptide is produced under pure physical process control with unique biological enzymolysis technology which can degrade the hard protein, which is difficult for the human body to digest (if the molecular weight is too small, the short peptide chains will result in the destruction of the biological characteristics, so people had better not use small peptides that’s molecular weight is below 1,000 D). So if we want to take in collagen, we had better choose the collagen peptide and the best choice is the active peptide, that is, the tripeptides.
In France, people actually refer to collagen peptide when they say collagen, because in their mind only collagen peptide can beautify the skin, and the name collagen used by them in short, is what we call collagen peptide.
It is worth pointing out that fish collagen peptide is the best choice to replenish collagen peptide. In the past, collagen was extracted from the bones and skin of pigs and cattle. With the outbreak and spread of mammal diseases (BSE and foot-and-mouth disease), Europe and the United States and other developed countries have enacted laws and regulations to prohibit the use of collagen from cows in the food and pharmaceutical industry. Therefore, under the premise of seeking safe raw materials, in France some senior enterprises have developed fish collagen extracted from fish scales and skins.
Fish collagen has the following advantages:
Safe in quality: There is no risk of being infected by diseases that pass form land mammal to humans.
Complete absorption because of the small molecular weight: The molecular weight of fish collagen is smaller than that of land-mammal collagen. Without a doubt, fish collagen peptide can be absorbed completely by the human body.
The collagen extracted and purified from fresh fish scales and fish skin does not contain cholesterol and fat.
Bien être tripeptide collagen powder, being a fish collagen finely processed under the French formula, is a kind of tripeptide with a triple-helical structure and a molecular weight of 2000 Dalton which offers the most stability and highest absorption rate. It can not only be directly absorbed by the skin, but can also simultaneously and efficiently balance the collagen loss of all parts of the body, making the skin moist, delicate, smooth, compact and elastic.
