I also take 1 capsule evenings of the calf bone concentrate "calcium hydroxyapatite" because it feeds the bones and teeth and has type 1 collagen which feeds the ligaments and tendons. I will always take it, although I still have a small amount of bending knee pain but it's no worse.

I also think I would have sensitive teeth if I didn't take calcium hydroxyapatite.

Some joints never heal with supplements, but I think the skeletal system still needs feeding and maintenance with these two supplements.
