What cartilage is

A smooth, resilient tissue covering the ends of bones at a joint, allowing them to glide against each other with minimal friction while absorbing mechanical load.

Why it has limited self-repair

Cartilage has no direct blood supply. It receives nutrients by diffusion from surrounding synovial fluid, which makes its capacity for self-repair considerably more limited than tissues with direct blood flow, such as muscle or bone.

Why it wears with age and use

Repeated mechanical load, combined with cartilage's slow turnover and limited repair capacity, means gradual thinning is a normal part of ageing for most people, accelerated by excess weight, injury and genetics.

Why supplements target the building blocks

Glucosamine and chondroitin are components of the cartilage matrix itself. The logic of supplementing them is providing raw material to a tissue that has limited ability to synthesise everything it needs on its own — not rebuilding damaged cartilage overnight.
