Query: Works Great, Prefer Cosamin ASU for me

Cosamin DS works very well. I have psoriatic arthritis that affects me the worst in my knees. This product keeps my knees in operational form. Missing a day or two is an obvious difference. However, I prefer the Cosamin ASU which not only helped my knees, but helps with overall inflammation quite a bit. It is more $$$$ though, so regular Cosamin DS is a very fair and less expensive alternative.
