Collagen is the most abundant protein in the human body. It acts like the glue that holds everything together—your skin, bones, joints, muscles, tendons, ligaments, and even your gut lining.
As you age, your natural collagen production declines, which can lead to wrinkles, weaker joints, and slower recovery. That’s why many people turn to collagen supplements for support.
But here’s the catch: not all collagen supplements are the same.
✅ The Different Types of Collagen (And What They Do)
Type I Collagen
- Found in: Skin, bones, tendons
- Best for: Skin, hair, nails, and bone strength
- Source: Commonly from marine or bovine collagen
This is the most common form of collagen in the body—around 90%! If you’re looking for anti-ageing benefits, stronger hair and nails, or better skin texture, Type I is your go-to.
Type II Collagen
- Found in: Cartilage
- Best for: Joint health and flexibility
- Source: Typically sourced from chicken cartilage
If you struggle with joint pain or want to protect your knees and shoulders during heavy lifting, Type II is ideal for cartilage repair and joint comfort.
Type III Collagen
- Found in: Skin, organs, and blood vessels
- Best for: Skin structure, gut health, and connective tissues
- Source: Common in bovine collagen, often alongside Type I
Type III supports elasticity in your skin and tissues, making it a great all-rounder for overall health.
🌊 Marine vs Bovine vs Chicken Collagen: What’s the Difference?
Let’s break down the most common collagen sources:
Marine Collagen
- Made from fish skin and scales
- Rich in Type I collagen
- Highly bioavailable (absorbs quickly)

Great for anyone focusing on complexion, wrinkles, or beauty-focused results.
Bovine Collagen
- Sourced from cow hide
- Contains Type I and Type III

A versatile choice for gym-goers, athletes, and anyone wanting full-body support.
Chicken Collagen

Ideal for people with active lifestyles, joint issues, or those recovering from injury.
🥤 What Form Should You Take?
- Powders – High-dose, usually unflavoured, easy to mix into shakes, smoothies, or coffee.
- Liquids – Convenient and fast-absorbing, often flavoured for easy drinking.
- Gummies – Tasty and great for daily skin, hair, and beauty-focused routines.
