Protein from pigskin is collagen, which is beneficial to the skin, but it can't be absorbed by the human body because of its large molecule. Even though most of the small molecular collagen is absorbed by bones, very little collagen actually reaches your face, which proves that the edible collagen on the market can't bring you any amazing changes. It's broken, beside the point!

I can tell you, it's useless for fitness. Fitness or whey protein.
