types of collagen and its functions

Collagen is a protein present in all animals and is the most abundant and widely distributed protein in our body. Its structure is fibrous. So far, 29 types of collagen have been detected in the human body, all made up of the same 18 amino acids (AA, basic structural units of proteins) and in equal proportions, differing only in the length, thickness and arrangement of their fibers. Several types of collagen coexist in each tissue. For example, in skin and bones we find type I generally associated with type V, in cartilages, there is type II generally associated with types VI and XI, in the wall of blood vessels type III is found generally associated with type XV.

If we talk about Hydrolysed collagen, it makes no sense to mention its type, because the process of hydrolysis (fragmentation of the protein chains) removes the type. The hydrolysis is necessary to transform the collagen protein present in animal tissues (native collagen) into an assimilable protein nutrient of reduced size peptides (associations of AA) with the same composition as any type of collagen. 

When we take Hydrolysed collagen, it is absorbed and reaches the bloodstream providing the same 18 AA and oligopeptides (associations of a few amino acids) in very similar proportions, regardless the type of collagen in origin from which the hydrolysate was obtained. This set of nutrients is used by different cells specialized in the production of collagen along the whole body, not only at the skin, or at the joints tissues, or at the bones… so at the whole collagen tissues of the body. 

For this reason, it makes no sense to emphasize the animal or tissue origin type of a Hydrolysed collagen products, as this ingredient serves to produce all types of endogenous collagen, regardless of the type of collagen from which it was obtained.

Thus, what is important about a Hydrolysed collagen is being a pure and bioavailable protein nutrient (its amino acids and peptides cross the intestinal barrier and reach the tissues via the blood). The type of collagen in origin will not make a significant difference of the final composition of the Hydrolysed collagen, so it is again indicative that it will not have more beneficial effects on one tissue than another. 

Therefore, the argument that taking Hydrolysed collagen from type I collagen has beneficial effects focused on the skin, and bones, or if it comes from type II collagen, on the cartilage, is false and is only a marketing tool used to differentiate from the competition, confusing the consumer, thanks to the fact that it sounds apparently “logical”, although it is not true.

Colpropur D®, the main ingredient of COLPROPUR® range of supplements, is an optimum quality Hydrolysed collagen produced by PROTEIN SA, a specialist in collagen since 1985. Scientific studies have shown its good digestibility and bioavailability, but also its beneficial effects on joints, bones, skin and immune system. This is because it provides the basic structural elements (collagen-specific AA and biopeptides) to synthesize all types of endogenous collagen in all body tissues.

This means that taking COLPROPUR® daily is an excellent food aid and a healthy habit easy to practice every day.
