Collagen for the skin.
The main function of collagen is to create and maintain the structures of the tissues that make up the body, including the skin, which is why it is of decisive importance in properties such as firmness and flexibility. The appearance of the skin, nails or hair is highly dependent on this protein. Although collagen production is irretrievably reduced with age, the intake of this food can restore a percentage of the levels of this substance in the body.
Sometimes, when taking collagen, distinctions are also made between protein from animals and that from fish, which is known as marine collagen.
