Can collagen repair knee cartilage?
Answer
No. No authorised claim exists for collagen and cartilage, and cartilage is predominantly type 2, which marine and bovine products do not provide.
Key takeaways
- Is there a repair claim?
- No. Collagen carries no authorised claim for cartilage or for anything else.
- Which type is cartilage?
- Predominantly type 2, from chicken sternum, rather than the type 1 in marine and bovine products.
- What helps a knee?
- Load management, conditioning, and a physiotherapist for anything not settling.
Two reasons this is a no
First, collagen carries no authorised health claim in the UK for cartilage, joints, tendons or ligaments. Vitamin C carries the claim available in this category, for normal collagen formation for the normal function of cartilage and bones, which is a nutrient supporting a normal process rather than repairing damage.
Second, the type is wrong. Cartilage is predominantly type 2 collagen, which comes from chicken sternum. Marine collagen is essentially all type 1 and bovine is type 1 with some type 3.
Why type matching would not settle it anyway
Even a type 2 product would not deliver type 2 to cartilage. Ingested collagen is broken into amino acids and short peptides in the gut, which enter the general pool and are used wherever the body is synthesising protein.
Nothing about having eaten a type directs the resulting building blocks to matching tissue, and no authorised claim rests on the idea that it does. The type on a label is a specification describing the source material.
What a knee actually needs
Assessment if it is painful, swollen, giving way or not settling with rest, and the speed of that matters more with a knee than with anything else. Then load management: minutes played, how the training week is built around the fixture, and being honest with a coach.
Futuro Labs Marine Collagen provides 1200mg of type 1 marine collagen with the vitamin C that carries the only claim in this category, at 28p a day. It is a nutrient intake and it has no role in repairing a knee.
