A small study on shark cartilage was reported at the American Society for Clinical Oncology in 1997 . Patients with advanced cancer were given shark cartilage for 12 weeks. Of the 58 patients treated, there was not one complete response or partial response to shark cartilage. Only 2 patients had significant improvement in quality of life. There are currently some ongoing studies of shark cartilage at a number of institutions, but no positive trials have been published in the scientific literature.
Shark cartilage is relatively expensive.
There are discount suppliers, but beware of utilizing some sources. Some producers do not supply pure shark cartilage and there may be additives and fillers.
