Has anyone here used collagen for joint relief?

I have done a bunch of research lately, read some (limited, to be sure) studies that call it “promising”, and talked to a couple of orthopods who are guardedly optimistic. I would love some first hand anecdotes.
Southern New England winters are Dickensian with cold, damp, snow, storms coming in off the North Atlantic, yuck. Hoping to find something to alleviate some of the joint misery.
Any personal experience with collagen would be appreciated.

Thanks, Jellies.
