SKIN & JOINT HEALTH

What Is Collagen and Which Type Do You Actually Need?

Collagen is the most abundant protein in the human body. It forms the structural scaffolding of your skin, joints, bones, tendons, ligaments, and gut lining. Think of it as the connective tissue that holds everything together — literally.

After your mid-twenties, collagen production begins to decline at roughly 1% per year. By your forties, the effects become visible: skin loses elasticity, joints feel less fluid, recovery slows. Supplementing with hydrolyzed collagen peptides is one of the most evidence-supported strategies to counteract this decline.

But not all collagen is the same. There are at least 28 known types, each with a distinct role in the body. Understanding the key types helps you choose a formula that actually matches your goals.

The Five Types That Matter Most

Type I — Skin, Hair, Nails & Bones

The most abundant collagen in the body, Type I is the primary structural protein in skin, tendons, bones, and connective tissue. It is responsible for skin firmness and elasticity, and is the type most directly associated with visible signs of aging.

Type II — Cartilage & Joint Health

Type II collagen is the dominant protein in cartilage — the cushioning tissue between joints. It is the most relevant type for those experiencing joint discomfort, stiffness, or reduced mobility.

Type III — Skin Elasticity & Gut Lining

Often found alongside Type I, Type III supports skin suppleness and the integrity of the gut lining and blood vessels. Particularly relevant for digestive health and skin hydration.

Type V — Cell Membranes & Hair

Type V plays a supporting role in the formation of collagen fibers and is found in cell membranes and hair. It works synergistically with Types I and III.

Type X — Bone Formation & Joint Cartilage

Type X is involved in bone mineralization and the formation of new cartilage — particularly relevant for bone density support and joint repair.

Which Type Do You Need?

The Case for Multi-Collagen

Single-type collagen supplements are targeted — useful if you have one specific concern. But for most people, a multi-collagen formula covering all five key types offers broader, more comprehensive support across skin, joints, bones, and gut simultaneously. The key is sourcing diversity: grass-fed bovine (Types I, III), chicken cartilage (Type II), and eggshell membrane (Types V, X).

What to Look for in a Collagen Supplement

• Hydrolyzed peptides — broken down for superior absorption
• Grass-fed, pasture-raised sources — cleaner sourcing, better amino acid profile
• Added Biotin & Vitamin C — Vitamin C is essential for collagen synthesis
• Hyaluronic Acid — works synergistically for skin hydration
• No fillers, artificial flavors, or sweeteners
