Discover the difference between Type I, II and III Collagen

If you've ever found yourself staring at shelves of collagen supplements, wondering what the difference is between Type I, II and III collagen, you're not alone.

So, let’s break it down. 

Understanding the types of collagen can help you choose a supplement that aligns with your wellness goals, whether that's glowing skin, stronger hair, or everyday joint support.

Here's your simple guide to collagen types explained.

First, what is collagen?

Collagen is the most abundant protein in the body, acting as the structural framework that helps support skin, bones, joints, muscles, and connective tissue.

As we age, natural collagen production gradually declines. This is why many women choose to add a collagen supplement to their daily routine as part of a proactive approach to skincare as they get older.

Type I Collagen

Type I collagen accounts for around 90% of the body's collagen and is found primarily in:

• Skin
• Hair
• Nails
• Bones
• Tendons

When people talk about collagen for skin, they're usually referring to Type I collagen.

Key type 1 collagen benefits:

• Supports skin elasticity and firmness
• Helps maintain skin hydration
• Supports healthy hair and nails
• Contributes to bone strength

Many premium collagen supplements use marine collagen as a rich source of Type I collagen.

Derived from fish, marine collagen is naturally rich in Type I collagen. Looking for a brand with a smaller collagen peptide size is worthwhile as it will be more bioavailable, meaning it's easily absorbed by the body (mention specifics of Collagen 500 Plus?)

If your focus is radiant skin, healthy hair, and overall beauty support, marine collagen is a popular choice.

Type II Collagen

Type II collagen is found predominantly in cartilage, the connective tissue that cushions your joints. 

Type II collagen supplements are primarily sourced from chicken. It is the type associated with collagen for joints and mobility support.

 

Key collagen benefits:

• Supports healthy cartilage
• Helps maintain joint comfort
• Supports flexibility and movement

If your priority is staying active, supporting exercise recovery, or looking after your joints as you age, Type II collagen may be worth considering.

Type III Collagen

Type III collagen is commonly found alongside Type I collagen and is present in:

• Skin
• Blood vessels
• Organs
• Connective tissues

Key collagen benefits:

• Supports skin structure
• Contributes to tissue strength and elasticity
• Works alongside Type I collagen to support overall skin health

Many bovine collagen supplements naturally contain both Type I and Type III collagen.

Sourced from cattle, bovine collagen typically provides a combination of Type I and Type III collagen, making it a versatile option for women looking to support skin, hair, nails, and overall connective tissue health.

How to choose the right collagen supplement

The best collagen supplement depends on what you're hoping to support.

Choose Type I collagen if:

• Your focus is skin health
• You want support for hair and nails
• You're looking for beauty-from-within benefits

 

Choose Type II collagen if:

• Joint health is your priority
• You lead an active lifestyle
• You're focused on mobility and flexibility

 

Choose Type I and III collagen if:

• You want broad support for skin and connective tissue
• You're looking for comprehensive healthy ageing support
  
  

When it comes to the types of collagen, choose what feels like the best fit for your goals. 

For skin-focused benefits, Type I collagen is the top choice. For joint support, Type II collagen is a good option.. And for overall structural support, the combination of Type I and Type III collagen can be a helpful addition to your daily routine.
