Unregulated, with Additives
-
As a dietary supplement, the Food and Drug Administration does not regulate shark cartilage. Evidence suggests that it may not offer effective treatment and, in fact, has certain risks attached. Some brands contain impurities, fillers and additives.
No Efficacy Against Cancer
-
M. D. Anderson Cancer Center clinical trials found no benefits for the shark cartilage cancer drug Neovastat (AE-941). The National Cancer Institute and American Cancer Society concur that studies show no cancer-fighting evidence.

Limited Arthritis Relief
-
Shark cartilage contains condroitin sulfate, but not enough to relieve knee pain or most arthritis symptoms, according to Creighton University's Altmed website.
High Calcium Content
-
Shark cartilage's high calcium content can elevate calcium levels in blood, leading to irregular heartbeat, especially when taken with calcium supplements. Large doses may affect blood sugar levels, a risk for diabetics.
Pregnancy and Children
-
Pregnant or nursing women, as well as children, should avoid shark cartilage; it may affect growth of developing blood vessels.
General Side Effects
-
The most common side effect is "taste alteration," according to Sloan-Kettering Cancer Center. Uncommon, possibly harmful, effects include nausea, vomiting, and anorexia. It may affect liver function over the long term.
