All About Collagen

Collagen is the most abundant protein in the body and helps give structure to our hair, skin, nails, bones, ligaments and tendons in our body. Thanks to collagen, we’re better able to move, bend and stretch. Collagen is also behind helping hair shine, skin glow and nails stay strong.**

What Are the Types of Collagen?

The three main collagen types can be found in Vital Protein’s line of collagen:

Type I: The most abundant collagen type, primarily found in skin, tendons, bones, organs, and the vascular system. It’s essential for skin and tissue repair.¹
Type II: Found mainly in cartilage; type II collagen is vital for joint health and mobility.¹
Type III: Commonly present in muscles, blood vessels, and bone marrow, type III collagen supports tissue structure and elasticity.¹

The Importance of Collagen for Aging

Our body's natural collagen production begins to decline as we age. We recommend supplementing with collagen and its necessary amino acids (glycine, proline and hydroxyproline) for healthy hair, skin, nails and joints.**
