The Basics of Collagen

Type I? Type II? Marine? Bovine? Powder? Capsule? Are you deciding which type of collagen to take or playing a round of go-fish? With all the collagen products on the market, it’s easy to get bogged down. Read on to find out what collagen really is, and which type is right for you.  

What is collagen? 

Collagen is found in all our connective tissues, tendons, ligaments and bones. It gives these body parts their strength, structure and elasticity. In the simplest sense, it’s the glue that holds everything together—and it’s essential for healthy growth and development.1  

Types of Collagen 

Did you know that there are 29 different types of collagen?1 The most popular are the kinds that support your tissues, like Type I, Type II and Type III collagen. Types I and III collagen are known for their skin, hair and nail benefits, while type II collagen is best for your joints.*  

Collagen Sources 

Since collagen helps build and maintain connective tissues—the structures that bind body parts together—it’s only found in animals. Types I and III collagen is often sourced from cows, while Type II collagen comes from chicken cartilage. There are also marine sources of collagen, like fish, that some people prefer due to its enhanced bioavailability. 

With so many sources, it’s plausible that certain types of collagen may be more effective than others. However, the research is unclear as to whether this is the case. 

Benefits of collagen 

You produce less and less collagen as you age. The good news is, a daily collagen supplement can slow that process, can help to improve skin health and elasticity and reduce signs of aging.*2,3 But that’s not all; collagen can help keep your joints healthy and comfortable too.*4  

Takeaway 

If you’re looking for a little extra support in the skin or joint department, collagen may be a good option. Look for a collagen powder sourced from grass-fed, pasture-raised animals to ensure quality and sustainability. And, whether it’s in powder or pill form, be sure to find a supplement that you’ll stick with. Afterall, consistency is key.
