1. Hydrolyzed Bovine Collagen

Bovine collagen comes from cows, specifically from their skin, bones and muscles. It’s made of mostly types 1 and 3 collagen, which is a good fit considering these are the most abundant types created and found in the human body. It’s a rich supply of glycine and proline, and therefore useful for creatine production, building muscle and also helping the body make its own collagen.†

2. Hydrolyzed Chicken Collagen

The type of collagen most abundant in chicken collagen is type 2, which is best for building cartilage. This makes it beneficial for joint health, especially since this source also provides chondroitin sulfate and glucosamine sulfate — both of which have anti-aging effects. †

3. Hydrolyzed Fish Collagen

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. †

4. Hydrolyzed Eggshell Collagen

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 pain/stiffness after strenuous exercise.†
