Studies are looking if shark cartilage stops new blood vessels from forming. Agents that do this are called angiogenesis inhibitors. This may help fight certain cancers by cutting off their blood supply. Studies are also being done to learn if angiogenesis inhibitors treat certain cancers. However, most of these inhibitors are stronger than those in shark cartilage. They don’t come from shark cartilage. Even the newer, more potent agents have not clearly shown to be effective against cancer.
Shark cartilage is also claimed to boost the immune system. It may help manage many diseases. These can include the following:
Skin issues, such as psoriasis
Retinopathies, such as diabetic retinopathy and macular degeneration
Breast, cervix, uterus, ovary, prostate, kidney, liver, and central nervous system cancer
