What is Collagen?
Collagen is the most abundant protein in the human body, making up about 30% of all protein content. It’s the essential building block for skin, joints, bones, muscles, tendons, and even hair and nails. However, after the age of 25, collagen production begins to decline — leading to signs of ageing, joint discomfort, and slower recovery.
Collagen supplements are designed to replenish your body’s natural collagen stores, often in the form of powders, capsules, or liquids, making it easier to support your health from the inside out.

Types of Collagen in Supplements
There are 28 types of collagen, but the majority of supplements focus on five key types:
Type I – Skin, bones, tendons
- Most abundant type (90%)
- Great for improving skin elasticity, reducing wrinkles, and strengthening hair & nails
Type II – Joints and cartilage
- Supports joint health
- Often found in products targeting arthritis or mobility
Type III – Organs and blood vessels
- Often paired with Type I
- Promotes skin firmness and gut lining health
Type V & X – Cell membranes, bones

- Usually found in multi-collagen formulas
Note: Most collagen supplements contain hydrolyzed collagen peptides, which are broken down for better absorption.
