Shark cartilage, the tough material that a sharks' skeleton is composed of, is dried and powdered to create this popular dietary supplement. Shark cartilage is claimed to combat and/or prevent a variety of illnesses, most notably cancer. It is often marketed under the names Carticin, Cartilade, or BeneFin. A derivative of it named Neovastat was tested by AEterna Zentaris as an angiogenesis inhibitor and showed promising results in animals. Two clinical trials of Neovastat were completed in 2007,showing negative results. Bovine cartilage (cartilage derived from cows) and shark cartilage have been investigated for many years as treatments for cancer, psoriasis, arthritis, and a number of other medical conditions.
