What is Collagen?
Let’s answer the question, “What is Collagen?” Collagen is the most abundant protein in the human body, making up about 30% of total protein. It is the primary building block for skin, muscles, bones, tendons, ligaments, blood vessels, and even the intestinal lining.

Key Roles of Collagen:
- Provides structure, strength, and elasticity to the body.
- Helps regenerate skin cells and gives skin its firmness.
- Supports muscles, joints, and connective tissues.
- Plays a role in healing wounds and blood clotting.
Types of Collagen:
- Type I: Makes up 90% of the body’s collagen, giving structure to skin, bones, tendons, and ligaments.
- Type II: Found in cartilage, supporting joints.
- Type III: Present in muscles, arteries, and organs.
- Type IV: Found in skin layers, responsible for filtration.
- Type V: Found in the corneas, hair, and placental tissue.
Collagen Decline with Age:
As we age, the body produces less collagen, leading to visible signs like wrinkled skin, stiff joints, and weaker muscles. Factors like smoking, sun exposure, and excessive sugar intake can accelerate collagen breakdown.
Maintaining a good collagen level involves a balanced diet (rich in Vitamin C, zinc, and copper), avoiding damaging habits, and protecting the skin from UV rays.
