The most abundant type of collagen found in chicken is Type 2 which supports strong cartilage. This makes it beneficial for joint health, especially since this source also provides chondroitin sulfate and glucosamine sulfate -- both of which promote healthy aging.

Collagen derived from fish is easily absorbed and provide mostly type 1 collagen, with the amino acids glycine, proline and hydroxyproline. Because type 1 can be found throughout the body, consuming more fish collagen is associated with benefits for the joints, skin, vital organs, blood vessels, digestion and bones. †

Egg collagen, found in the shells and whites of eggs, contains mostly type 1 collagen. It also has type 3, 4 and 10, but by far the most type 1, just like the human body (approximately 100 times more type 1 than type 4). It provides glucosamine sulfate, chondroitin sulfate, hyaluronic acid and various amino acids that have benefits for building connective tissue, promoting supple skin, building muscle mass and reducing stiffness after strenuous exercise.†
