Shark Cartilage: Benefits, Possible Side Effects, and More
Shark head and shark skeleton/cartilage, Shark cartilage is most famously used for cancer, are sold at a local dry seafood store.

The Shark extract, which is gotten from the shark’s dried and powdered cartilage, is well-known for treating various cancers, including Kaposi’s sarcoma, which primarily affects HIV-positive persons. [1]

Shark cartilage supplements also treat osteoarthritis, plaque psoriasis, age-related vision loss, wound healing, diabetes-related retinal impairment, and intestine inflammation (enteritis). [2]

For arthritis and psoriasis, most people prefer to apply shark cartilage to the skin directly, whereas, for cancer, other people apply shark cartilage to the rectum.

However, there is no evidence that shark cartilage is effective in cancer and disease prevention. Cartilage Health professionals have raised concerns concerning possibly harmful substances identified in shark cartilage that have been linked to Alzheimer’s disease.

Where Does It Come From?

Shark cartilage is gotten from the elastic and tough tissue taken from sharks caught in the Pacific. Before the extraction, the cartilage is dried and grounded into a powder.

Shark cartilage is used to make various extracts, including squalamine lactate, U-995 [3], and AE941. Proteoglycans, glycoproteins, and carbohydrates are the primary components of shark cartilage. [4]

What Does Shark Cartilage Do?

Shark cartilage may obstruct the formation of new blood vessels, which are required for cancer to spread. It may also stop blood vessels from growing in psoriasis lesions. This could aid in the healing of these wounds. [5]

Shark Cartilage Benefits

Even though there is no scientific evidence, shark cartilage may provide health benefits such as:

Cancer prevention and treatment:
The natural, harmless component is thought to help treat and prevent cancer. The Food and Drug Administration is currently conducting clinical trials on shark cartilage. [6]

Treats osteoarthritis:
Shark cartilage relieves arthritis symptoms when coupled with camphor, chondroitin sulfate, and glucosamine sulfate. However, whether shark cartilage is absorbed via the skin is unknown. [7]

Improve eyesight in individuals with age-related vision loss:
Previous studies have shown that using shark cartilage for twenty-four weeks improves the vision of people with age-related vision loss.

Treats skin problems:
Is eating cartilage good for you? Current studies suggest that applying shark cartilage to the skin or eating it can help with psoriasis and irritation.

Psoriasis is relieved.

Wound healing, vision issues, kidney malignancies, and other ailments are among the various health benefits of shark cartilage.
