What Are The Health Benefits Of Shark Cartilage? Learn Its Uses, Side Effects & More

What is Shark Cartilage?

Shark cartilage refers to a tough elastic tissue, similar to bones, whose extracts are used for medical purposes.

The extract, which is obtained from the dried and powdered cartilage of the shark, is commonly used in treating different types of cancer particularly Kaposi’s sarcoma, which mostly affects people infected with HIV.

In addition, Shark cartilage extracts are used for psoriasis, arthritis, eye damage caused by diabetes, and enteritis (intestinal inflammation).

However, there is no evidence to demonstrate the efficiency of Shark cartilage in cancer and disease prevention. In fact, health experts are raising concerns about potentially toxic compounds found in shark cartilage associated with Alzheimer’s disease.

Where does it Come from?

Shark cartilage comes from the tough elastic tissue derived from sharks caught in the Pacific Ocean. The cartilage is dried and ground into powder before extraction is carried out.

Different types of extracts are made from Shark cartilage including U-995, AE941, and squalamine lactate. The main compounds in shark cartilage include proteoglycans, glycoproteins, and carbohydrates.

The idea behind the use of shark cartilage in the fight against cancer is because cancer doesn’t seem to appear in sharks. Its use became popular since 1993 after a TV news magazine showed how cancer patients in Cuba went into remission after they were treated using shark cartilage.

What are its Possible Health Benefits?

Although there is no scientific evidence, the possible health benefits of shark cartilage include:

  • Treat age-related vision loss: Previous studies indicate that the use of shark cartilage for 24 weeks improves vision in patients with age-related vision loss.
  • Treats skin problems: Undergoing researches suggest that topical application or oral consumption of shark cartilage can ease skin symptoms including itching and psoriasis.
