What does it do? Cartilage, derived from shark and bovine (cow) sources, is a type of connective tissue comprised of mucopolysaccharides, protein substances, calcium, sulfur, and collagen. Early research in the 1950s and 1960s, using chips of bovine cartilage inserted into wounds, demonstrated that cartilage enhances wound healing.1 2 Since then, cartilage has been investigated for its potential role in regulating immune function and to stop the growth of tumors.3 The role of shark cartilage in inhibiting angiogenesis (the growth of new blood vessels) is hypothesized to be beneficial in halting the growth and spread of cancer;4 however, this remains to be proven by research.
| Where is it found? Cartilage is derived from either sharks or cows. Cartilage has been used in connection with the following conditions (refer to the individual health concern for complete information): Who is likely to be deficient? Since it is not an essential nutrient, cartilage is not associated with deficiency states. A few studies suggest that individuals with cancer may benefit from cartilage supplements;5 6 however, well-designed research is lacking, and many experts question the use of cartilage in this regard. A similar situation is seen with the use of cartilage in individuals with arthritis. How much should I take? Anyone who is interested in taking bovine or shark cartilage supplements should consult a nutritionally oriented doctor for advice. |

| Are there any side effects or interactions? People with elevated blood levels of calcium should not take large amounts of cartilage. It has been suggested that some people should not use a cartilage supplement, this concern is based only on theory, not clinical evidence. These would include those with cardiovascular disease, women who want to be or are pregnant, nursing mothers, anyone having or having had surgery within thirty days, and athletes training intensely. None of these contraindications has been proven, however. |
