Quality and it really helped "lubricate" my joints
I am impressed with the strength and purity of this collagen supplement but almost equally impressive is the proper mix of Collagen types.  So many many only have one or two types of collagen.  This is as complete as I have seen.  And while you wouldn't necessarily see or feel any immediate impact, within two weeks from starting I had substant8ial reduction in pain on a arthritic joint (finger) that had an osteophyte.  Worth every penny not to cringe any more when I move my right index finger
