Shark Cartilage: The Controversial Marine Supplement for Joint, Immune, and Cellular Health
Once dismissed as an alternative curiosity, shark cartilage has gained renewed interest in the supplement world for its anti-inflammatory, immune-regulating, and joint-supporting properties. While its origins may seem unconventional, modern formulations and emerging research are shining light on this once-taboo ingredient.
What Is Shark Cartilage?
Shark cartilage is a powdered extract made from the tough, elastic connective tissue of sharks. It’s rich in:
Chondroitin sulfate – Supports joint health and cartilage regeneration
Calcium and phosphorus – Important for bone structure
Angiogenesis inhibitors – Compounds that may block blood vessel growth, explored for tumor suppression
Mucopolysaccharides – Immune-modulating and anti-inflammatory effects
Why is it popular?
Joint and Bone Health
Shark cartilage is used as a natural source of chondroitin, which may:
- Relieve joint pain
- Slow cartilage breakdown
- Improve flexibility and mobility
Immune Modulation
Shark cartilage may balance immune response and support natural killer (NK) cell activity, helpful for chronic inflammation and autoimmune regulation.
Anti-Angiogenesis Properties
In the 1990s, shark cartilage gained fame for its potential role in inhibiting blood vessel growth, which some hypothesized could limit tumor growth. While more human data is needed, research continues into its application in cellular protection and cancer therapy adjuncts.
Calcium-Rich Bone Support
High levels of calcium and phosphorus make it supportive for bone density, especially in aging populations.
Market Outlook
Though niche, the marine-based joint health market is resurging, driven by natural alternatives to NSAIDs and a growing distrust in synthetic pharmaceuticals. According to Grand View Research, the joint health supplements market is expected to grow at 8.1% CAGR through 2030, with chondroitin and glucosamine maintaining strong demand.
