In case anyone is interested in collagen, there are 3 types of collagen: marine, plant and animal. 

I did lots of research and it actually seems marine (fish derived) collagen is the best one! It's the purest, the most easily absorbed (something to do with bioavailability) and most effective. These links explain it best:
