Types of Collagen and Their Sources: A Guide to Choosing the Right Collagen

Types of Collagen and Their Sources: How to Choose the Right One for You

Collagen is the most abundant protein in the human body. It forms the structural foundation of the skin, bones, joints, hair, and nails. As we age, collagen production naturally declines, leading to wrinkles, joint weakness, and hair thinning. That’s why collagen supplements have become increasingly popular.

But the key question is: What are the different types of collagen? What are their sources? And how do you choose the right one?
