Shark Cartilage
Also known as: Cartilage Powder, Shark Cartilage Powder, Bovine Cartilage
Shark cartilage is a source of glycosaminoglycans (GAGs) and collagen promoted for joint and connective tissue support, though clinical evidence for efficacy remains limited and inconsistent.
Primary uses
- Joint health support
- Cartilage integrity
- Connective tissue support
How it works
- Provides glycosaminoglycans (chondroitin sulfate, keratan sulfate) and collagen peptides
- Potential anti-inflammatory effects
- May support extracellular matrix synthesis
Dosage
- Typical range
- 750–1,500 mg daily
- Timing
- Any time of day; consistency recommended
- With food
- May be taken with or without food
- Duration
- Benefits typically assessed after 4–8 weeks of consistent use
- Special populations
- Pregnant/nursing women should consult a healthcare provider; individuals with shellfish allergies should exercise caution

- Capsule· 70/100
- Tablet· 70/100
Safety
Common side effects
- Generally well tolerated
- Rare: mild gastrointestinal upset, nausea

- Bleeding disorders or anticoagulant therapy (theoretical concern)
Evidence notes
Limited clinical trials with mixed results; most evidence is preliminary or from animal/in vitro studies. Lacks the robust RCT support of established joint ingredients like glucosamine or collagen peptides.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
