Some chondroitin comes from shark fins, as in this ad:

It can also come from cattle cartilage, which probably doesn't have high concentrations of the prions that cause mad cow disease. The Mayo Clinic says that it is not clear that chondroitin confers additional benefits beyond what glucosamine alone offers, so I just take the glucosamine sulfate and hopefully save a shark or two.
