    Collagen As A Protein (Is it Complete or Incomplete?)


    Collagen has been making quite a splash in the health and wellness world, touted for its skin-enhancing and joint-supporting benefits.

    But when it comes to protein, is collagen packing a complete punch or falling short in providing all the essential amino acids our bodies need?

    In this blog post, we'll dive into the composition of collagen as a protein source, explore whether it's complete or incomplete, and discuss how you can ensure your body gets all those vital building blocks it needs for optimal health. Shall we?

    Key Takeaways

    • Collagen is a protein that contains 19 out of the 20 amino acids needed by our bodies, but it lacks one essential amino acid - L-tryptophan. This renders collagen an incomplete protein source. (1)
    • Essential amino acids like L - tryptophan are crucial for various biological processes, such as synthesizing serotonin and maintaining immune function. Thus, combining collagen with other protein sources containing these essential amino acids is crucial. (2)
    • To make collagen a complete protein, pair it with other high-quality proteins like grass-fed beef or whey protein powder or consume diverse plant-based proteins throughout the day.
    • Prioritizing variety and balance in your nutritional choices is critical to achieving optimal health outcomes.

    Collagen as a Protein

    Collagen is considered a protein due to its primary function of providing structural support to connective tissues, but it differs from other proteins in terms of its amino acid composition.

    Collagen protein composition

    Collagen is a protein that serves as the body's primary structural component. It's found abundantly in animal bones, skin, and connective tissues.

    Even though collagen may not rank as a complete protein - missing just one essential amino acid, L-tryptophan - it doesn't skimp on delivering substantial perks for those who enrich their diets with it.

    For example, many fitness enthusiasts turn to collagen supplements after workouts because they aid muscle recovery while also improving overall hair, nail, and bone health.

    Essential amino acids for a complete protein

    To maintain optimal health, your body requires nine essential amino acids for various biological processes. Here is a list of those essential amino acids:

    1. Histidine
    2. Isoleucine
    3. Leucine
    4. Lysine
    5. Methionine
    6. Phenylalanine
    7. Threonine
    8. Tryptophan
    9. Valine

    Your body can't produce these vital amino acids on its own. You must snag them from your diet. Food or supplements, like collagen or organic health products, are the ticket. They serve up the crucial nutrients for your overall well-being.

    Analyzing collagen's amino acid profile

    Collagen's amino acid profile can provide valuable insight into its protein composition and completeness.

    The table below displays the amino acid profile of collagen, which contains 19 of the 20 amino acids required by our body. However, note that collagen is missing L-tryptophan, an essential amino acid. (3

     Amino Acid Presence in  Collagen
    Alanine Yes
    Arginine Yes
    Asparagine Yes
    Aspartic Acid Yes
    Cysteine Yes
    Glutamic Acid Yes
    Glutamine Yes
    Glycine Yes
    Histidine Yes
    Isoleucine Yes
    Leucine Yes
    Lysine Yes
    Methionine Yes
    Phenylalanine Yes
    Proline Yes
    Serine Yes
    Threonine Yes
    Tryptophan No
    Tyrosine Yes
    Valine Yes


    Yes, collagen lacks L-tryptophan, making it an incomplete protein. But don't dismiss its power! It champions your skin, joints, and overall health. Pair it with other protein sources. This combo unlocks a complete amino acid profile, turbocharging your nutrient intake and boosting your well-being. (4)

    Is Collagen a Complete Protein?

    Collagen is not considered a complete protein due to its lack of L-tryptophan, one of the essential amino acids needed for a protein to be considered complete.

    Difference between complete & incomplete proteins

    Complete proteins contain all nine essential amino acids required by the body. The body cannot make these essential amino acids, so they must be obtained from food sources.

    On the other hand, incomplete proteins lack one or more of the essential amino acids. Plant-based protein sources like legumes, nuts, and seeds fall into this category.

    The role of tryptophan in protein completeness

    Tryptophan is an essential amino acid that plays a significant role in making proteins complete. It is one of the nine essential amino acids our body needs to function correctly and cannot be produced by the body.

    While collagen protein contains most of the necessary amino acids, it lacks tryptophan, which makes it an incomplete protein. Tryptophan is required for various body processes, such as synthesizing serotonin and melatonin, maintaining a healthy immune system, and regulating mood.

    Therefore, combining collagen with other protein sources like whey or pea protein is essential to get all these crucial amino acids.

    How to make collagen a complete protein

    Collagen is an incomplete protein, but there are ways to make it complete. Here's how:

    1. Combine collagen with other protein sources with the missing essential amino acid, L - tryptophan. This includes foods like turkey, chicken, and pumpkin seeds.
    2. Take a complete protein supplement alongside your collagen supplement. Whey protein is an excellent option since it contains all nine essential amino acids.
    3. Pair collagen with plant-based proteins daily to ensure you get all your essential amino acids.
    4. Consider eating grass-fed beef or pasture-raised chicken, which are high-quality protein sources that can help complement collagen's missing amino acids.

    Following these tips ensures you get all the essential amino acids needed for a healthy diet, even though collagen may be incomplete in this area.

    Factors contributing to collagen's incompleteness

    The reason why collagen is deficient in L-tryptophan lies in its composition – it is primarily made up of nonessential amino acids that are not used to build other types of proteins.

    To make up for this incompleteness and ensure a good balance of essential and nonessential amino acids, collagen can be combined with other protein sources, such as grass-fed beef or whey protein powder.

    Importance of combining collagen with other protein sources

    To ensure you are getting all nine essential amino acids necessary for overall health, combining collagen with other protein sources in your diet or supplement routine is crucial.

    For example, adding grass-fed beef or pasture-raised chicken into your meals can provide other essential amino acids that complement the incomplete profile of collagen.

    You can achieve a complete amino acid profile that supports muscle growth, immune function, and energy production by combining different protein sources.



    In the realm of protein prowess, collagen falls just shy of complete perfection. Though it boasts an impressive array of 19 vital amino acids, there's one key player missing from its lineup: L-tryptophan.

    While collagen works wonders for skin health and joint function, it cannot stand alone as a complete protein.

    But fear not, for there is a path to protein perfection! By joining forces with other protein sources, collagen can ascend to the realm of wholeness.

    Embrace the power of combination and unlock the potential of all nine essential amino acids, delivering the fuel your body craves.

    Let your protein journey reach its zenith as you embrace the synergy that propels you toward optimal health. Together, we shall conquer the realms of protein greatness!
