The word “collagen” comes from the Greek word for glue, and for good reason—it’s the main protein holding our bodies together. It’s especially critical for cartilage, the tissue that cushions our joints.
When osteoarthritis causes cartilage to wear down, collagen provides more than just structural support—it actively protects joints and helps them move more comfortably. That’s why collagen supplements are gaining ground as therapy for early osteoarthritis. The key is using the right type and amount.
Why Collagen Matters for Joint Health
Collagen is the most abundant protein in the human body. It forms a big part of tendons and ligaments, but unlike muscle or bone, it breaks down faster as we age. In fact, collagen loss starts as early as our 20s and 30s, and by the time we reach 80, up to 75 percent of the body’s collagen may be gone. Collagen loss can increase our susceptibility to injury and joint problems.
