    Comparing Ingredients: Collagen I, II & III

    Stiff joints, sagging skin, and weak bones may all have one thing in common: loss of collagen.

    Collagen is a protein found in connective tissues throughout the body. This fibrous protein gives structure to joint cartilage, tendons, skin, bones, and nearly every organ in the body, which makes collagen crucial for overall health and graceful ageing.

    Unfortunately, collagen production begins to decrease by the time you reach your mid-twenties. This collagen decline may make it necessary to take a collagen supplement in order to keep joints mobile and comfortable, skin youthful, and bones strong.

    CollagenWhile there are nearly 20 types of collagen within the body, there are three main types of collagen – collagen I, II, and III – and each form of collagen plays a specific role. Discover the function of each collagen, and decide what kind of collagen supplement is best for you.

    Collagen I
    Found in skin, tendons, bones, and ligaments, collagen I is a triple–stranded helical molecule that is 300 nm long. [1] Collagen I is the most abundant collagen in the body and is generally the most common type of collagen added to supplements.

    Who should take collagen I: Those who want to support skin’s elasticity, joint and muscle health, and maintain collagen levels as you age.

    Collagen II
    Type II collagen is best known for its arthritis supporting qualities. It’s naturally found in cartilage and in the eyes, and it is the least abundant collagen type in the body. Its form is similar to type I but smaller in diameter.

    Who should take collagen II: Individuals with joint problems or arthritis may benefit from taking collagen II. This type of collagen specifically supports joint cartilage strength, comfort, and overall health.

    Collagen III
    Collagen type III is often found along type 1 in the body. It is the second most abundant collagen found in the body and is nearly identical to collagen I. It’s naturally found in the skin, artery walls, intestines and uterus. Oftentimes, type III and type I are combined in supplements.

    Who should take collagen III: Individuals concerned about ageing skin due to lack of collagen would benefit from collagen type III. This type of collagen is the first to decline with age, and supplementing with type III may help restore skin elasticity.
