Joint/Skin

Shark Cartilage

Also known as: Cartilage Powder, Shark Cartilage Powder, Bovine Cartilage

C
Evidence

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

Forms

  • Powder· 70/100
  • Capsule· 70/100
  • Tablet· 70/100

Safety

Common side effects

  • Generally well tolerated
  • Rare: mild gastrointestinal upset, nausea

Contraindications

  • Shellfish allergy (cross-reactivity possible)
  • 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.
