Proteins provide us with their digestion the amino acids that the blood then offers to the different tissues of the body to form them first and then repair their wear.
Our collaborator Amlsport tells us in this article what are the differences between the different types of collagen that we can find in the market
Tendons (which hold the joints) like cartilage and the organic matrix of bone are proteins, specifically COLLAGEN. Proteins provide us with their digestion the amino acids that the blood then offers to the different tissues of the body to form them first and then repair their wear.
There are people with problems who have been recommended to take shark cartilage or marine collagen. It is correct and, although it is not a tease, it is a "pocket tease".
Why? Because when they offer you that product, you will never know if it is a shark, hake, or fish bones, scales and skin, or of species of low economic value (trash) and they charge it as if it were a shark in the case of "cartilage shark ”.
Keep in mind that all collagens are practically the same; that is why they can be injected into the lips without rejection and, furthermore, collagen is a protein that fibroblasts and chondrocytes make and take it out of the cell. That is, it is a secretion and, consequently, those fibers that are outside the cell do NOT have DNA from the nucleus and therefore cannot be identified as belonging to this or that animal.
Simply explained, when we take collagen, whether it is a terrestrial or a marine animal, being the protein alone, our organism does not differentiate if that collagen is of marine or terrestrial animal origin and absorbs either of them in the same way. It is important to know that the benefits of collagen do not depend on the species from which it is extracted, what is important is that it is hydrolyzed in order to digest it.
Hydrolyzation is a process in which fat and unwanted materials are removed and amino acids remain, which is what interests us about collagen. With this process collagen is pre-digested (the protein is broken down into smaller parts (amino acids) that are possible to digest). So it is necessary that collagen is always hydrolyzed.
On the other hand, vegetable gelatines are NOT proteins, because although they have the same appearance as collagens, they are pectins; that is, carbohydrates.
