Shark Cartilage

Shark cartilage is claimed to fight cancer, based on a 1992 book Sharks Don't Get Cancer, by William Lane. However, research into this hsharksas shown it to be ineffective and in fact the premise, that sharks don't get cancer, has been shown to be incorrect.

Does it Work?

Shark cartilage has been shown to be ineffective in fighting cancer in several studies by the Mayo Clinic and the National Cancer Institute. In addition, more than 42 types of cancer have since been discovered in sharks.

In addition, the active agent, a protein found in the shark cartilage, needs to be in the bloodstream to have any effect, and in capsule form it is digested by the body before entering the bloodstream.


Because of the lack of evidence, we do not recommend purchasing or taking shark cartilage.
