Type II Collagen: The Joint-Specific Collagen Most Supplements Miss
If you've been taking collagen for months and your joints still feel the same, there's a straightforward explanation. The collagen you're taking almost certainly doesn't contain Type II — the only collagen type that directly supports cartilage.
This isn't a minor detail. Type II collagen makes up 50-60% of all protein in cartilage tissue. Without it, your joints get nothing from your supplement — no matter what the label says.
Cartilage is the smooth, rubbery tissue that caps the ends of your bones where they meet at joints. It absorbs impact, reduces friction, and allows your knees, hips, shoulders, and hands to move smoothly.
Type II collagen is the structural backbone of this tissue. It forms the fibrous network that gives cartilage its strength and resilience. When Type II depletes — and it starts declining around age 25 — cartilage thins progressively. Less cushion. More friction. More stiffness.
The body can't substitute other collagen types for Type II. Type I won't repair cartilage. Type III won't cushion your knees. Each type has a specific job, and Type II's job is joints.
The vast majority of collagen supplements on the market are single-source bovine or marine products. Bovine collagen delivers Types I and III. Marine collagen delivers Type I. Neither one contains any Type II whatsoever.
Type II collagen can only be reliably sourced from two places: hydrolyzed chicken collagen and avian sternum cartilage. These are specialized ingredients with dedicated supply chains — which is why most manufacturers skip them entirely.
It's cheaper and simpler to sell a bovine-only product and market it as "collagen for joints." But the biology doesn't support the claim. Without Type II, there's no cartilage benefit.
Encore Collagen Complex includes both chicken collagen and avian sternum — two dedicated Type II sources — plus bovine, marine, and eggshell membrane for complete five-type coverage.
Get Complete Joint Support →Avian sternum collagen deserves special mention. Beyond delivering Type II collagen, it naturally contains three compounds that are critical for joint lubrication: Glucosamine, Chondroitin, and Hyaluronic Acid.
These are the building blocks of synovial fluid — the lubricant inside every joint capsule. Most people buy Glucosamine and Chondroitin as separate supplements for $20-30 each. With avian sternum collagen, they're included naturally as part of the same ingredient.
This is why source matters. A supplement that lists "Type II collagen" from chicken alone gives you the structural protein. One that includes avian sternum gives you the structural protein plus the lubrication system.
Joint collagen supplementation follows a predictable timeline. Weeks 1-4, your body is accumulating the peptides and beginning to use them for maintenance. Weeks 4-8, cartilage tissue begins responding — inflammation markers decrease and flexibility improves. Weeks 8-12, most people report noticeably less stiffness and greater ease of movement.
The effect is cumulative. Unlike pain medications that mask symptoms temporarily, collagen supplementation supports the actual tissue. The longer you take it, the more your cartilage has to work with.
Encore Collagen Complex delivers 1,800mg of five-source collagen daily — with dedicated Type II from both chicken and avian sternum for maximum joint and cartilage support.
Type II collagen is the primary structural protein in cartilage. It cushions joints, reduces friction between bones, and supports smooth, pain-free movement.
Type II collagen is sourced from chicken collagen and avian sternum cartilage. It cannot be obtained from bovine or marine sources.
Yes. In fact, taking all five types together is ideal. Type II handles joints while Types I, III, IV, and V support skin, tendons, cellular repair, and collagen fiber organization.
1,800mg of five-source collagen per serving. Third party tested. GMP certified. 90-day money-back guarantee.
