What no one has been able to explain to me is why collagen isn’t treated like any other ingested protein and proteolysis doesn’t take place. I.e. protease breaks the collagen into basis’ amino acids?

Hi, you’re basically asking how collagen supplements do what they claim to do. As I understand it, protein in the diet is broken down by the stomach acids into long-chain amino acids, whereas the hydrolysed collagen in collagen supplements is broken down into short-chain amino acids that the body recognises and knows what to do with. Plus, the presence of more of collagen in the body prompts our bodies to create more of its own. Totally Derma has tested this to show that the product not only makes it through the stomach but shows up in the skin,
