Best Collagen Powder: Reviews and Buyer’s Guide


With so many collagen supplements on grocery store shelves, how can you choose the best collagen powder for your goals?

In this guide, we’ll walk you through what collagen is, the benefits of collagen, and then break down some of the top brands out there. 

Whether you’re looking for a powder, capsule, or chewable option, there is something out there for everyone.

What Is Collagen?

Collagen is the most abundant protein in your body. It makes up the vast majority of your connective tissue and provides structure and function to your bones, skin, ligaments, and tendons. 

As you age, your production of collagen naturally starts to decline. This can result in injury to your joints, bones, and is also the culprit for aging skin (loss of elasticity and wrinkles). 

There are at least 16 types of collagen, but 80-90% of the collagen in your body consists of type I, II, or III[*]. 

Types of Collagen

The functions of the three primary types of collagen include[*][*]:

  • Type I: Type I collagen is the predominant form of collagen in your skin, tendons, bones, and pretty much anywhere in your body where there is an extracellular matrix (ECM). Its primary function is to bring strength to your tissues. 
  • Type II: Type II collagen is the main component of cartilage, allowing for flexibility and structure in your joints. 
  • Type III: Type 111 collagen is an important component of blood vessels, hollow organs, and skin, and brings flexibility to your tissues.

3 Main Benefits Of Collagen

The majority of research on collagen falls into one of three categories; skin health, joint health, and gut health. Let’s dive a little deeper into each:

#1 Skin Health

Collagen, being an essential part of your extracellular matrix, is crucial for the health of your skin. Your extracellular matrix (ECM) acts like scaffolding for your skin. It holds the layers of your skin in place, keeping them elastic and firm. That’s why, as you age, your skin may appear less elastic and more wrinkled[*]. 

Research shows, however, that taking collagen as a supplement can enhance the appearance of your skin, improving elasticity and even helping with the appearance of cellulite[*][*].

#2 Joint Health

Collagen is a crucial component of your cartilage, which allows for the flexibility and structure of your joints. Due to the natural aging process, or from overuse, the cartilage in your joints naturally breaks down over time. This can result in severe joint pain, injury, and can sometimes even call for surgery. 

Research shows that collagen supplementation reduces activity-related joint pain, and may even improve symptoms of osteoarthritis[*][*].

#3 Gut Health

While the claims around collagen supplementation and gut health still need more clinical research to back them up, there are promising clues that collagen may help strengthen and heal your gut lining.

Many people suffer from a condition known as “leaky gut,” where the lining of your gut becomes inflamed, allowing undigested food particles and toxins into your system. 

Leaky gut has been linked to a number of other health conditions, including autoimmune disease, and digestive disorders like celiac disease and inflammatory bowel disease (IBD)[*]. 

Collagen plays a crucial role in maintaining the integrity of your gut lining, and changes in the ECM of your gut have been associated with the chronic inflammation that often leads to leaky gut. 

Furthermore, research shows that people with inflammatory bowel disease present with lower levels of collagen in their blood[*]. This is definitely a case of correlation as opposed to causation, but certainly worth mentioning.
