Reply to comment by DooDooSlinger in If collagen is a protein, and proteins are broken down during digestion, why would collagen or collagen supplements be beneficial? Is it just hype? by skepticated

I'm happy to be corrected. Mostly I wanted to push back on the myth that proteins are somehow digested into some sort of universal protein sludge that's completely interchangeable.

My primary point is that we get glycine from collagen and that we need it because we can't make enough. I'm sure your expertise exceeds mine, but do I have that right?

It's unclear - the mechanism is far from understood. We get glycine from almost any protein source so that's definitely not it. But oligopeptides can definitely have hormonal effects so who knows, maybe degradation products of collagen exert hormonal effects which lead to increased synthesis. Obviously totally hypothetical
