Speaking of gelatin, many people may feel that they have not been exposed to such substances, but this is not the case. It is a frequent visitor in our life. It appears in many of our foods in the form of additive gelatin, such as soft candy, ice cream, cotton candy, etc., most of which are made of additive gelatin. In addition, it also contains collagen.

The main ingredient of edible gelatin is hydrolyzed collagen, usually from pig skin or cow bone. In some preliminary studies, it was found that hydrolyzed collagen can reduce the pain caused by bone and joint wear.

The scientific basis that may be beneficial to joints is that collagen supplements are rich in peptides and amino acids (glycine, proline and hydroxyproline) and can produce collagen in articular cartilage. The other two types of collagen allowed for sale are more primitive collagen and edible gelatin, which are extracted from collagen, but do not degrade compared with enzyme-hydrolyzed collagen.

Although collagen, edible gelatin or hydrolyzed collagen must be degraded to absorb amino acids in the process of digestion, mouse experiments show that the absorption rate of hydrolyzed protein is high due to its small molecule. It can be seen that edible gelatin is rich in collagen.
