Shark cartilage is a dietary supplement made from the dried and powdered cartilage of a shark; that is, from the tough material that composes a shark's skeleton. 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.
The benefits of this supplement have not been scientifically proven, nor has shark cartilage been reviewed by the U.S. Food and Drug Administration (FDA). However, its pervasive use is due to the incorrect notion that sharks do not get cancer. This idea became popular with the best-selling book Sharks Don't Get Cancer by Dr. William Lane, published in 1992. This assertion even appears in the film on sharks at the Monterey Bay Aquarium (although the aquarium does not endorse the use of shark cartilage).
Kind of like the old joke about why eating carrots is good for your eyes, have you ever seen a rabbit wearing glasses ?
Have you ever heard of a shark with prosate cancer ?
There are thousands of men who have been cancer free after brachy without taking anything special. And there are those who have taken every good there is and still have a reoccurence.
And, there are many sellers of supplements out there who love to make good money selling us unproven supplements.
I think the guys on here who advocate a heart healthy diet, exercise, and weight mamagement are the closest to the truth on this stuff. Even if it doesn't help, you feel great anyway.
Welcome to HW. Beware of those selling supplements that are proven to prevent cancer.
