Collagen’s health benefits are catching on, and as they do, more and more people are diving deeper into the science behind collagen nutrition. You may have heard by now that there are a number of different "types" of collagen. Put simply, these different types are essentially representative of the area of the body from which the collagen was sourced. While there are many different collagen types, types I, II and III are the most common types of collagen you’ll find in supplements. You can get these healthy proteins in your diet by consuming bone-infused foods, such as eating cartilage directly off the bone, consuming bone-in fish, eating organ meats or drinking bone broth. An even easier way to top up your collagen levels is by taking a whole-food collagen supplement. Vital Proteins Collagen Peptides and Marine Collagen are rich in types I and III. If you’re more interested in a nourishing source of type II collagen, Vital Proteins’ Cartilage Collagen will do the trick. Keep reading to find out more about these different types of collagen.

Type I Collagen

Type I collagen is the most prevalent type of collagen in the body. This is the type of collagen you’re probably thinking about if you’re interested in preserving the levels of collagen in your skin, hair or nails. It is worth noting that, like all types of collagen, levels of type I collagen begin to decline after about age 25. Because it is so prevalent in the connective tissues, we often see the decrease of type I collagen resulting in characteristics such as sagging skin, fine lines, brittle nails and thinning hair.But type I collagen isn’t just a beauty-related substance. It’s also a major component of the tendons, organs and bones. This makes it a vital component of any diet or wellness routine — especially if you’re staying active as you age. Collagen Peptides are primarily composed of type I collagen.

Type II Collagen

Another common collagen type to find in supplements is type II collagen. Though somewhat less prevalent in the body than type I, type II collagen is extremely important. It is the main component of cartilage and is extremely healthy for the skeletal system. Active people who need to rely on their joints may also benefit from adding type II collagen into their diet. Our Cartilage Collagen is composed of type II collagen.

Type III Collagen

Type III collagen is also found in Vital Proteins’ line of collagen products. The third commonly found type of cartilage, Type III, is generally found in reticular fibers, such as in the bone marrow. It’s usually found alongside Type I collagen in the body.
