What is collagen?

Simply put, collagen is a protein that forms the connective tissue all over our bodies. It is found in skin, nails, bones, joints, ligaments, and tendons. Collagen is primarily made up of amino acids and makes up about 70-80% of the dry weight of your skin.[2]

Why your body needs collagen

As the most abundant protein in the body, collagen plays a key role in maintaining healthy-looking hair and skin, joint and bone health, and can help build muscle mass and support an active lifestyle.[2,3]  Here’s the unfortunate biological reality though: the older you get, the less collagen your body produces. It starts to decline between ages 18-29. By 40, we may lose about 1% per year. This may lead to weaker and more brittle hair and nails, less mobility, a loss of skin elasticity, and more visible fine lines and wrinkles.[2,3] 

5 MAIN TYPES OF COLLAGEN

When it comes to supplements there are five main types of collagen, types I, II, III, V, and X. Although each of them is linked to different wellness benefits, here are the five commonly found collagen types:

Type I

This is the most abundant collagen in the human body, found in skin, bone, ligaments, and even teeth. Type I collagen is the primary building block of your skin, and may support skin elasticity and hydration. Bovine collagen is a common source of type I collagen. [3,4]
