Type I—This type accounts for 90% of your body’s collagen and is made of densely packed fibres. It provides structure to skin, bones, tendons, fibrous cartilage, connective tissue, and teeth.
Type II—This type is made of more loosely-packed fibres and is found in elastic cartilage, which cushions the joints.
Type III—This type supports the structure of muscles, organs, and arteries.
Type IV—This type helps with filtration and is found in the layers of your skin.
Simply put, collagen is said to be the “glue” that holds our bodies together. In our youth, our body produces all the collagen it needs, allowing for firm skin, supple joints, and strong bones. However, production levels start decreasing after you turn 30, gradually leading to physical signs like older-looking skin, thinner hair, brittle nails, stiff joints, and slower recovery from physical activity. In addition to the natural loss of collagen with age, other factors such as hormonal changes, use of drugs and alcohol, consumption of hydrogenated oils, sugars, and processed foods, exposure to chemicals and radiation, and stress can all contribute to the loss of collagen in our bodies. Therefore, supplementing with a high-quality collagen supplement is a steadfast way to get ahead of the most common signs of ageing.
In an ideal world, we would be getting doses of collagen from our diets. Collagen is abundantly found in animal connective tissue, skin, bones and cartilage (especially in bovine—cow collagen), however, very rarely do we consume adequate amounts of these sources.
