Collagen 101: Why Types I–V Matter for Your Skin, Joints, and More

Collagen is the most abundant protein in your body—it keeps your skin smooth, joints moving, and tissues strong. But as we age, collagen production naturally slows, leading to wrinkles, stiff joints, and weaker hair and nails. The good news? Supplementing with collagen can help support your body from the inside out.

Let’s break down the five main types of collagen and why they’re important.

The Five Types of Collagen and Their Benefits

  • Type I – The most common type, found in skin, bones, tendons, and ligaments. It helps with skin elasticity, wound healing, and bone strength.

  • Type II – Found mainly in cartilage. Supports joint comfort and mobility—great for people with stiff knees, hips, or shoulders.

  • Type III – Present in skin, muscles, and blood vessels. Promotes skin firmness and cardiovascular health.

  • Type IV – Found in the layers that surround organs and skin. Plays a role in filtration and tissue structure.

  • Type V – Found in the eyes, hair, placenta, and some connective tissues. Supports cell growth, healthy hair, and tissue strength.

By choosing a collagen supplement that includes multiple types, you’re giving your body more complete support.

Why You Should Consider Collagen

  1. Healthy, Glowing Skin – Helps reduce fine lines and wrinkles while boosting hydration and elasticity.

  2. Joint and Bone Support – May reduce stiffness and help you stay active.

  3. Stronger Hair and Nails – Promotes growth and strength, reducing breakage.

  4. Gut and Tissue Health – Supports connective tissues that line your digestive tract.

How to Use Collagen

  • Form: Most people use collagen powders, which can be mixed into coffee, smoothies, or water. Capsules are also available if you prefer convenience.

  • Timing: Anytime of day works—what matters most is consistent daily use.

  • Pair With Vitamin C: This is key! Vitamin C is necessary for your body to actually build and repair collagen. Without it, collagen supplements aren’t as effective. Try adding a vitamin C-rich food (like citrus or berries) or take your supplement alongside a vitamin C capsule. General daily requirement (adults): Women: 75 mg/day ; Men: 90 mg/day
