Discover the truth behind whether or not collagen protein can be used to build muscle mass. Learn how this protein can help you reach your fitness goals and the unique mechanisms behind how it’s possible. 

Did you know that collagen is one of the most abundant proteins in the human body? (1) Collagen protein is vital to various connective tissues in the human body, including skin, tendons, ligaments, and bones. (2)  

If you are reading this article, you have been training hard in the gym and working towards building the physique you have always dreamed of or accelerating your athletic performance.  

To do so, you are looking for a way to accelerate your lean muscle mass growth and a new addition to your daily routine beyond the common recommendations you hear in training circles.

Organic Protein 

Such as increasing calorie consumption, optimizing your protein sources with protein supplements, and consuming just the right amount of carbohydrates pre-and post-workout.  

These are the "bread and butter" of training programs aiming to enhance muscle mass, as you cannot out-train a poor diet. But there are ways to add just one percent or more improvement to your nutritional protocol that can significantly increase skeletal muscle in the long term.  

Consuming a collagen supplement may be just what you need to aid in the exercise-recovery effects of your workouts.

In this article, we will dive into collagen consumption's benefits and role in muscle recovery and connective tissue protein synthesis so that you can confidently add to your arsenal of dietary supplements and gain a competitive advantage in the gym. 

Does Collagen Build Muscle? 

According to several studies, collagen supplementation does not affect muscle protein synthesis or muscle size when combined with resistance training compared to milk-derived proteins such as whey (3)  


This may surprise some as collagen is not a primary muscle-building protein for the human body like other types of protein, such as whey protein.  

However, research supports the idea that collagen protein supplementation can play an additional role in your fitness goals such as supporting connective tissues.  

Collagen's Role in Connective Tissue  

Collagen plays an important role in supporting connective tissue, particularly tendons and ligaments. Tendons and ligaments connect muscles to bones and bones to each other, respectively, forming a network that facilitates the movement of our muscles.

After exercise, the role of collagen synthesis aids the repair and strengthening of these connective tissues. For example, in young adults, exercise when combined without collagen supplements boosts collagen protein synthesis above baseline, highlighting the remodeling of collagen protein after exercise. However, how does collagen supplementation affect our connective tissues after exercise?  


Below, we will dive into the benefits of collagen supplementation post-exercise.  

Stimulating Protein Synthesis 

Protein synthesis is the process of recovering from exercise and supporting recovery. When you step inside the gym to train, the goal is to perform exercises that break down muscle tissue so that protein synthesis is triggered, and your skeletal muscles and connective tissue repair and grow stronger.  


Protein synthesis is stimulated by several factors, with the primary triggers being intense training, adequate protein present in the diet, and hormones like insulin and testosterone.  

Based on research, one of the benefits of collagen supplementation post-exercise is that it can help kick-start this process and enhance the benefits of resistance exercise based on its rapid digestibility. (1)

Increased Amino Acids 

Amino acids are proteins' "building blocks" and can help increase muscle fiber size over time. These building blocks can be made by the body (non-essential), consumed via the food you eat, or supplemented via protein supplements you drink after training (essential). 

By taking collagen protein supplements, amino acids found within the protein can be consumed at the right time to maximize the muscle-building response you get from training. (3) 

Collagen molecules are exceptionally high in the amino acids' glycine, proline, hydroxyproline, and arginine which can contribute to muscle repair post-exercise.  

After muscle fibers are damaged with each repetition, they require ample amino acids from protein sources to recover and rebuild. These amino acids are necessary for muscle repair and without them, muscle growth is not possible.  

The combination of arginine and glycine also contributes to increased Creatine synthesis. (3) An increase in creatine allows for more energy or adenosine triphosphate (ATP) in the body (3).  

More ATP results in more work being done in a single session, either through increased repetitions or weight. (3) Which can ultimately result in muscle mass improvements over time.  

An uptick in creatine in the body also improves recovery post-exercise, allowing for more frequent or high-intensity training and more muscle mass to be built. (3) 

Collagen Protein vs. Whey Protein 

If you compare collagen protein to whey protein, you will find some similar aspects to these two types of proteins, but also definitive differences that set them apart. 

Both proteins are rapidly digesting, meaning when you consume them, they are quickly broken down by the body and absorbed into the bloodstream to be sent to the parts of the body that need them.

Rapid digestion makes them ideal for post-workout supplementation because you want to send nutrients to the muscles you just worked as soon as possible after training.  

Collagen and whey protein differ in that collagen protein is derived from animal connective tissues such as ligaments, tendons, skin, and bones. While whey protein comes from dairy sources. 

When consumed in adequate amounts, they both provide a high amount of amino acids that are used for muscle remodeling, but whey protein has an advantage over collagen. This is because it has a more complete amino acid profile containing branch chain amino acids (BCAAs) such as leucine, isoleucine, and valine. (4) 

Both of these proteins can help you build muscle. Whey protein may be the best option for maximizing muscle building due to its BCAA content.

Collagen Protein FAQ 

How do you take collagen Supplements for muscle building? 

The research studies that showed a positive effect on muscle mass gains had subjects take 15g of collagen dissolved in 250 mL of water after each training session for 12 weeks. (2) 

Can I take collagen every day? 

Yes, you can! Collagen was taken daily by the subjects in the research studies we reviewed, while the control group received no supplementation to compare. 

Does collagen count as protein? 

Yes, collagen is the most abundant protein in the body, providing structure for connective tissues such as ligaments, tendons, nails, hair, and skin. (2)
