At a glance
Insufficient
evidence for shark cartilage
Our honest take
Shark cartilage capsules from SciTec, 75 to a pot. We could not confirm the amount per capsule, the daily dose or the calcium content, so we cannot work out a cost per day. There is no good evidence that shark cartilage does anything for joints and no authorised claim for it; a standard chondroitin product gives a known dose.
- You have specifically chosen shark cartilage and accept the evidence is poor
- You are allergic to fish, vegetarian, or avoid shark products for sustainability reasons
- You take calcium or have high blood calcium, kidney stones, or a heart or circulation condition: check the label with your GP
- You are pregnant or breastfeeding
The science
Shark cartilage· evidence: Insufficient
Shark cartilage powder contains chondroitin, other cartilage compounds, protein and a lot of calcium. It was heavily promoted in the 1990s, but well-designed trials did not support the claims made for it at the time.
There is no good evidence that taking shark cartilage does anything for joints, and no authorised health claim for it, so we make no claims about its effects. If you want chondroitin, a standard chondroitin supplement gives you a known amount. Some buyers also avoid shark products for sustainability reasons.
Typical dose: Products usually suggest 2–5 g a day
Safety: Contains fish (shark). High in calcium: count it towards your total if you take other calcium supplements. Speak to your GP first if you have a heart or circulation condition, high blood calcium or kidney stones, or are pregnant or breastfeeding. Can cause stomach upset and an unpleasant taste.
