I think collagen is a great add on, I do think the actual product makes a huge difference though. There are several different types of collagen out there from several different sources (bovine and marine mostly). The product I use is a liquid marine type 1 collagen that is sourced from a specific area and I fully stand by it. I also use a turmeric/tart cherry product daily to help reduce inflammation as well as adaptogens to lower cortisol levels.
