Collagen Types I, II, and III: Which One Is Right for You?

Collagen is one of the most talked-about supplements in the United States today—and for good reason. As the most abundant protein in the body, collagen is essential for skin elasticity, joint mobility, gut health, and overall vitality. But when you shop for collagen, you’ll quickly notice that there are different types: Type I, Type II, and Type III. Understanding the differences can help you choose the right one for your unique health goals.

Why Collagen Matters More Than Ever

According to the National Institutes of Health, collagen production naturally declines after the age of 25, dropping by about 1% every year. This decrease contributes to visible aging signs like wrinkles and sagging skin, as well as stiff joints and slower recovery. That’s why more than 60% of U.S. consumers now use collagen supplements to support beauty and mobility, according to a 2023 industry report.

Collagen Type I: The Beauty Protein

Type I collagen makes up around 90% of your body’s collagen. It’s found in skin, hair, nails, tendons, and bones. This is the go-to collagen for those focused on:

• Smoother, firmer skin
• Reduced fine lines and wrinkles
• Stronger nails and shinier hair

Expert Insight: Dermatologists often recommend hydrolyzed Type I collagen peptides because they’re easier for the body to absorb and directly support skin renewal.

Collagen Type II: The Joint Protector

Type II collagen is primarily found in cartilage. It’s a powerhouse for:

• Joint comfort and flexibility
• Reducing stiffness after exercise
• Supporting mobility as you age

Clinical studies have shown that undernatured Type II collagen can significantly reduce joint discomfort in adults within just 90 days of supplementation.

Collagen Type III: The Wellness Partner

Often found alongside Type I, Type III collagen supports:

• Skin elasticity
• Gut lining and digestive health
• Vascular strength (important for circulation)

Type III is sometimes called the “youth collagen” because of its role in maintaining skin plumpness and supporting overall tissue structure.

How to Choose the Right Collagen

• If your primary goal is beauty and skin health, choose Type I or a blend of Type I & III.
• If you’re struggling with joint pain or mobility issues, Type II is the best match.
• If you want overall wellness support, a multi-collagen blend that includes all three types is a smart choice.
