Shark Cartilage - Uses And Side Effects
Shark Cartilage, in the true sense of the term, is just that--cartilage tissue from a shark. Shark cartilage is a dietary supplement that some people claim fights cancer. It comes from the spiny dogfish shark, Squafus acanthi as, and the hammerhead shark, Sphyma few/ni. Shark cartilage gained popularity as a nutritional supplement in recent years based on reports that sharks do not get cancer and that the cartilage from sharks in supplement form is useful in connection with cancer. Unfortunately, sharks can get cancer and there is no evidence that can confirm that shark cartilage prevents cancer in humans.
Shark cartilage has been heavily promoted as an anti-cancer agent. Some in vitro and animal studies show some anti-angiogenic properties. Inhibition of wound angiogenesis has recently been demonstrated in one study of human subjects given liquid shark cartilage extract, but there are no other human data related to shark cartilage's putative anti-angiogenic effects and certainly none that show this effect in cancer patients.

Important points to remember
What the research shows
Usually, the digestive tract can't absorb the large molecules in shark cartilage. So it's doubtful that taking shark cartilage orally can release usable compounds into the blood. Also, no wellcontrolled clinical studies have been published. In 1994, the National Cancer Institute began a trial of shark cartilage-but stopped it when they found that each batch of shark cartilage (provided by advocates) was contaminated. At this time, no evidence shows that shark cartilage offers benefits to people with cancer.
