Well, I think what they would say is like there's, because you're getting hydroxyproline in the collagen that you're taking that probably, I don't know how much hydroxyproline is typically in the diet, you know?
And that's done, apparently the, nobody needs to know this, but just for fun stuff, the hydroxyproline helps stabilize the structure because of the hydrogen bonding with the hydroxyl molecules, which I found interesting.
