Type I collagen is the most abundant form of collagen in the body and can be found in your tendons, skin, bones, cartilage, connective tissue, and teeth.

In another study, women supplementing with collagen peptides containing type I collagen were shown to have reduced cellulite and wrinkles.

Type II collagen is mostly found in cartilage and plays an integral role in the health of your joints and tendons.

This makes perfect sense, as type II collagen contains constituents known to help with joint health, such as glucosamine and chondroitin sulfate.

Type III collagen can be found in high amounts alongside type I collagen.

Type III collagen is also found in your muscles, organs, and a connective tissue called reticular fiber, which helps restore the gut and other tissues to ensure they are running smoothly.

Type V collagen helps the formation of all cells, but especially cells in your hair, gut, and skin.

Type V collagen plays a critical role in the formation of fibrils for our cells and has been shown in research to help improve skin moisture retainment.

Type X collagen has been shown to support new bone formation and tissues to help improve joint health, such as articular cartilage.

Type X collagen has been shown to be beneficial when it comes to bone healing, too!
