Collagen is the most abundant protein in our bodies, especially type 1 collagen. It’s found in muscles, bones, skin, blood vessels, digestive system and tendons. It’s what helps give our skin strength and elasticity, along with replacing dead skin cells. When it comes to our joints and tendons, in simplest terms, it’s the “glue” that helps hold the body together.
Our body’s collagen production naturally begins to slow down as we age. We can thank this degenerative process for signs of aging, such as wrinkles, sagging skin and joint pains due to weaker or decreased cartilage (hello, skeleton legs). Other lifestyle factors — like eating a diet high in sugar, smoking and high amounts of sun exposure — also contribute to depleting collagen levels. It’s been found that collagen-related diseases most commonly arise from a combination of either genetic defects, poor intake of collagen-rich foods, nutritional deficiencies and digestive problems affecting production (synthesis) of collagen.
