Chondroitin Q

This is the joint supplement "Oncare Chondroitin Q Joint Solution" that I take every evening. The product contains 95% chondroitin Q and is made from shark cartilage extract powder. The recommended dosage is once a day. I often go on long hikes, so I take it because I'm worried about my knee joints, but I don't really know if it works. As long as it doesn't get worse, I plan to continue taking it consistently.
