Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Cartilage, particularly in the form of supplements like shark cartilage or bovine cartilage, has been explored for its potential to support joint health. The rationale is that cartilage contains compounds such as collagen, chondroitin sulfate, and glucosamine—substances that are natural components of human cartilage. Scientific interest has focused on whether orally consumed cartilage or its constituents can aid in the maintenance or repair of joint tissues, especially in conditions like osteoarthritis.

However, the evidence supporting the efficacy of cartilage supplements for joint health is limited and mixed. Systematic reviews and clinical trials have generally found that while some individuals report symptomatic relief, the overall benefit compared to placebo is minimal or inconsistent. Most of the supportive data comes from studies on chondroitin and glucosamine, rather than whole cartilage supplements. Furthermore, there is little evidence that ingested cartilage directly contributes to the repair of damaged joint tissue.

In summary, while there is scientific rationale and some preliminary evidence for the use of cartilage-derived compounds in joint health, high-quality clinical trials generally do not strongly support the use of cartilage supplements for joint support. The evidence base is therefore rated as low to moderate (2 out of 5).
