Reply to comment by carlos_6m in ELI5: if protein is broken down into peptides in the stomach/digestive tract, why would consuming something like "active collagen" do anything? by Alexander_Elysia

Studies actually do show that collagen peptides do work. That means your mechanistic understanding is wrong.

Theyre testing a compound with a crapton of other things known to work, not just collagen, and its a test against placebo, that doesn't stablish mechanistic at all you nugget!

That was just a one off study I found. There are numerous studies and sources. Pretty much every decent study and source suggests that they work.
