Collagen for Joint and Tendon Health: What Type Works Best?

Written By Kyle Hildebrandt

If your joints feel stiff or your tendons seem slow to heal, collagen might be part of the reason why. As we age — especially if we’re sitting a lot or not as active as we used to be — our natural collagen production starts to drop. This decline can lead to joint discomfort, tendon irritation, and slower recovery from workouts.

Let’s break down what collagen does, which types matter most, and how to supplement it effectively.

What Is Collagen?

Collagen is the most abundant protein in the body. Think of it as the "glue" that holds your joints, tendons, and connective tissue together.

There are several types of collagen, but Type II Collagen is the star when it comes to joint health. It’s the primary type found in cartilage — the stuff that cushions and protects your joints during movement.

Why Collagen Matters for Joint and Tendon Health

Low collagen levels can lead to:

  • Joint stiffness or discomfort

  • Slower healing from injuries or overuse

  • Decreased resilience in tendons and ligaments

  • Reduced recovery from workouts, especially strength training

For active adults or anyone over 40, daily collagen support can make a noticeable difference in how your joints feel and function.

Benefits of Collagen Supplementation

  • Improves joint comfort and mobility

  • Supports tendon resilience and healing

  • May reduce exercise-related joint pain

  • Aids in soft tissue repair and recovery

Bonus Nutrient: Hyaluronic Acid

Some high-quality supplements pair collagen with hyaluronic acid — a natural substance that acts like joint lubrication. It’s even used in joint injections for arthritis, but when taken orally, it may support smoother, more comfortable movement in daily life.

What to Look for in a Collagen Supplement

For best results, check the label for:

  • Undenatured Type II Collagen (UC-II®) – proven to support joint cartilage and comfort

  • Hydrolyzed Collagen Peptides – easier to absorb for general soft tissue repair

  • Added Hyaluronic Acid – helps joint lubrication

  • Vitamin C – necessary for collagen synthesis in the body

My Recommendation

If you’re dealing with joint or tendon pain — or just want to stay ahead of it — collagen may be worth adding to your routine.

For joint health, look specifically for UC-II® on the label. It's different from regular collagen peptides and has strong research behind it.
