What are Collagen Peptides?

what are collagen peptides

Collagen is a buzz word that you’ve likely heard around the nutrition isle at the grocery store and among health-conscious friends. But just what are collagen peptides and why are they significant? What are their benefits? And, what are the best collagen peptides to supplement with? In this article, we’ll dive into all of these questions and help you navigate the world of collagen in general.

What is Collagen and What are Collagen Peptides?

To grasp what collagen peptides are, it’s important to have a firm understanding of collagen first. Collagen is protein that comes from animals. It is in fact found in fish, mammals and humans. Collagen is a building block of connective tissue, cartilage, skin and bone. Collagen supplements tend to come from cows (bovine) or fish (marine). Collagen peptides are simply extremely small pieces of collagen. It’s as easy as that!

Essentially, collagen proteins are broken down, usually through a process called hydrolysis, into even smaller pieces that can be more easily digested and absorbed by our bodies—thus making it a more effective method than whole collagen for supplementation.
That’s it! Collagen peptides are simply a very absorbable supplemental form of collagen. But let’s dig a bit deeper into why you’d want to take these supplements to begin with.

What Are the Benefits of Collagen Peptides?

Because collagen plays SUCH an important role in our bodies—and our bodies naturally begin to produce less collagen as we age—collagen peptides can help replace this collagen loss. Essentially, collagen peptide supplements support our body’s ability to make collagen so we can stay looking young and healthy.
Specifically, since collagen peptides have been broken down into tiny pieces, they’re easier to absorb into the digestive tract. Once absorbed, the body can put them to good use!
Incidentally, it’s also thanks to the fact that collagen peptides are so small (with a very low molecular weight), that they can dissolve in hot or cold water—making them incredibly easy to supplement with!

What Are Collagen Peptides Good For?

Ok, so now we know what collagen peptides technically are and we know some of the benefits—but what are collagen peptides good for? Why would you care to supplement with these little amino acids?

Well, for one thing, collagen peptides are a fantastic source of protein. If you need a good protein supplement, collagen is easy to add to any drink—be it a smoothie, coffee or even ice water—thanks to it’s high absorbability. You can even add it to soups or broths. It doesn’t add any weird texture or flavor, so it’s incredibly versatile. But collagen peptides are also good for so much more.

Collagen peptides help to hydrate and decrease signs of aging in the skin. They can support healthy hair and nails. They can ease joint pain and support healthy connective tissue. Collagen peptides even help with gut health, helping to heal leaky gut syndrome and supporting the integrity of the digestive tract. And, there’s more.

Collagen peptides may also help with heart health by strengthening blood vessel walls. It can increase bone mineral density, especially important for those at risk of osteoporosis. Essentially, collagen can keep us youthful, flexible and healthy. Pretty impressive.

What Are the Best Collagen Peptides?

When it comes to supplementing, there are a few things to consider in order to find the best collagen peptides for you. Collagen supplements typically come from one of two sources: bovine and marine.

Bovine: Bovine collagen is made from the skin and bones of cows. Bovine collagen is high in collagen Type 1 and Type 3, which have different uses for the human body.

Marine: Marine collagen (also known as fish collagen) supplements are typically made from fish scales, which are tremendously high in Type 1 collagen, which is the most abundant form of collagen in the human body. Fish collagen is usually more environmentally friendly because scales can be sourced from fish that will go to the food market—thus there’s no need to catch more fish to produce the collagen. Fish collagen is also smaller and more digestible than bovine collagen, implying it will be more effective.

Collagen can of course be sourced from other animals as well, such as chicken or pig, but you won’t see these on the market so often. Another important factor to notice when choosing a collagen supplement is whether it’s hydrolyzed or not. Hydrolyzed means the collagen has undergone the process discussed earlier in this article that breaks the peptides into ever smaller peptides—making it more bio-available (easily absorbed) to your body.

How to Increase Your Collagen Levels

Obviously, supplementation with collagen peptides is a great place to start.
Also remember that there are lots of natural ways to get more collagen into your diet. For example, you can eat lots of bone broth, organ meat, eggs and fish with the skin still on. Consuming foods with high levels of proline and glycine is also important, as these nutrients are necessary for your body to make collagen and thus support collagen in your body. Vitamin C is also critical to collagen production, so be sure to get this important vitamin into your diet daily!

What Does Collagen Do?


Collagen is a big buzz word of late. Why is everyone talking about and supplementing with this protein? Wat does collagen do? And when there are so many different types of collagen on the market, how do you know what type to take? Like, what is better between bovine and marine collagen—and what are collagen peptides? And how does collagen work when we supplement with it?

We’ll get to all these questions below, but first, let’s come to a solid understanding of what exactly collagen is—and why it’s so important for the human body.

What is Collagen?

Collagen is a protein. In fact, it’s the most abundant protein in the human body, creating the bulk of our physical bodies. It’s found in our bones, muscles, tendons, cartilage, blood and skin.

Specifically, collagen makes up the connective tissue. Connective tissue connects all the other tissues, holding all of our cells together and giving our tissues strength and flexibility. It’s the support system or the structure that holds the rest of our bodies together.

There are in fact 28 different types of collagen in the body. However, Type I collagen is by far the most prevalent, making up about 90% of all the collagen in our bodies. Types II, III and IV are also found in high quantities, and are also essential for overall health.

Collagen is found in all animals, not just humans. Mammals and sea creatures—such as fish and sharks—produce collagen. That’s why most collagen supplements are bovine (beef) or aquatic.

Although our bodies create collagen naturally, it begins to break down and is not produced in as great of quantities as we age. That’s why people supplement. But we’ll get more into the supplements in a minute. First let’s review how our bodies make collagen and how we can support this natural process.

How Do Our Bodies Create Collagen?

Our bodies create collagen by combining amino acids, which are the building blocks of protein.  And where do we get these amino acids? From eating proteins, such as fish, dairy and beans.

Our bodies also need zinc, vitamin C, and copper to produce collagen. If you want your body to produce healthy amounts of collagen, it’s important to get a well-rounded diet that includes all of these nutrients.

Following is a breakdown of some of the foods that contain large amounts of the amino acids and nutrients essential for collagen production:

  • Proline: Is an essential amino acid with high sources of Proline found in animal products and other high-protein foods, such as organ meats like liver, bone broth, beef, chicken, and fish.
  • Glycine: Another essential amino acid. Glycine is found in gelatin powder, bone broth, poultry skin, seafood and meat, dairy products, legumes, spinach, dried seaweed, watercress, asparagus and cabbage
  • Vitamin C: We all know we need Vitamin C for our immune systems, but we also need it for collagen production. It is found in high quantities in citrus fruit, strawberries, bell peppers, tomatoes, broccoli, cabbage and more.
  • Zinc: One of the minerals essential for collagen production, zinc is found in whole grains, nuts such as cashews, shell fish, eggs, dairy and more.
  • Copper: Another critical mineral, copper is found in organ meat (especially liver), shellfish, beans (such as kidney beans and chickpeas), pumpkin seeds, spinach and more.

It’s always important to eat a diet high in the nutrients our bodies need to be healthy, strong and flexible. And, while it’s important to eat a diet rich in the nutrients listed above for efficient collagen production, we can also support our bodies by supplementing with collagen to ensure our bodies are getting as much as needed.

Why Supplement With Collagen?

Collagen is responsible for keeping our bodies strong and healthy. For example, it’s essential for healthy, strong nails, full hair, muscle mass, strong bones and supple skin. Collagen supports digestive health, eye health, heart health and kidney health.

Collagen also keeps our joints healthy and can ease the pain of osteoarthritis. There’s even evidence that supplementing with collagen can help build muscle mass, when taken alongside resistance training.  

However, we know that as we age our bodies produce less collagen. We also know that certain things such as sun exposure, lack of sleep, alcohol consumption and cigarettes will lead to collagen breaking down at a greater rate.

So, why supplement with collagen?

Well, many people take collagen to keep their skin hydrated and elastic. Afterall, collagen makes up roughly 70-80% of the entire skin surface. People take collagen to keep their skin looking young and healthy. Others take collagen to keep their joints and tendons flexible, strong and pain free. Others take collagen to assist in building muscle mass.

Many take collagen for a combination of these reasons. However, pretty much everyone who supplements collagen does so to keep their bodies fit, healthy and youthful.

How Does Collagen Work?

Collagen supplements work by giving your body the necessary proteins it needs to build collagen. When your body absorbs the short chain amino acids through the small intestine, it can then put them to use wherever the body most needs collagen.

Collagen works best when taken in high quantities. In fact, research indicates that 10 grams per day is needed to see results.

Luckily, Köll Marine Collagen powder dissolves easily into water, coffee or juice and is flavorless, so it’s easy to incorporate such a large dose into your routine.

Marine collagen peptides powder

Collagen also works better when you take collagen supplements that are highly bioavailable. Bioavailable means easily absorbed by the body and obviously, if you’re taking collagen, you’ll want maximum absorption to ensure you’re really getting the required amount necessary to see a big difference.

Types of Collagen Supplements

There are primarily two types of collagen supplements on the market: Bovine Collagen (made from beef) and Marine Collagen (also known as fish collagen).

Marine collagen is far more bioavailable than beef collagen. It’s also far higher in Type I collagen—the most abundant type of collagen in the body and essential for that supple skin and strong hair and nails we love.

Collagen supplements come in capsules, gummies, drinks and powders. The powders allow you to get the highest dose, which, as mentioned above, is really important when it comes to collagen supplementation. 

When looking at collagen powders, you’ll want to make sure you’re getting collagen peptides, because these are the most bioavailable. But what are collagen peptides?

What Are Collagen Peptides?

A peptide is a short chain of amino acids. So, collagen peptides are simply shorter chain collagen proteins.

Because they’re so short, they are much more bioavailable to the body. And, because they’re more bioavailable, you can take smaller doses to achieve the same results as the longer chain collagen supplements.

Collagen peptides are often called under their full name: hydrolyzed collagen peptides.

This refers to the process through which the peptides are broken down. The process is called hydrolysis and it uses water—not toxic chemicals—to break the chain of amino acids to the smallest and most usable form: hydrolyzed collagen peptides.

Incidentally, it’s also thanks to this process of shortening the amino acid chains that makes powdered collagen so easy to dissolve into any liquid, hot or cold.

In Conclusion…

Now we know how collagen works and why it can be a fantastic supportive supplement!

Just remember to always eat a complete diet that supports collagen production, and avoid things such as stress and sun exposure that will speed collagen degeneration. And when you want to support your body’s natural collagen production, supplement with the highly bioavailable marine collagen peptides.

Do Collagen Supplements Work?


If you’re reading this, you probably already know that collagen is the protein that binds tissues in all fish and animals, including humans. In fact, it is the basis of our connective tissues—including our skin, tendons, ligaments and cartilage.

Sadly for us, however, collagen begins to break down as we age. After about age twenty, our bodies simply don’t replace collagen at the same rate. In fact, our bodies produce an enzyme called collagenase that destroys collagen.

In light of this, it makes intuitive sense that ingesting collagen, such as marine collagen supplements, would help to sustain a higher quantity of collagen within our bodies—thus supporting our bones, tendons, joints and skin.

But do collagen supplements work?

Well, there are a number of studies that say yes—not to mention thousands of personal accounts. But before we get into them, let’s review why you would want to take fish collagen supplements —or any other collagen—to begin with.
Why Supplement With Collagen?

Collagen supplements support the body’s natural process. Collagen is essential for maintaining and repairing our bones, tendons and joints. We also need collagen to maintain youthful, hydrated skin.

Our bodies actually produce collagen on their own, primarily out of the amino acids proline, glycine and lysine. However, as mentioned, our bodies stop producing collagen as efficiently after around age twenty.

That’s where supplementation can make a big difference in supporting our skin health. You see, collagen in concentrated in fish skin and animal ligaments. So, when we eat fish collagen supplements or bovine collagen supplements, we are ingesting a wide variety of amino acids, which our bodies use to make collagen.

The more collagen the better, because it can help plump our skin, diminish wrinkles and lines, and give us an overall fresh skin look. It can also possibly help diminish joint pain and arthritis and support overall healthy aging.

How Do Collagen Supplements Work?

Well we know the more collagen our bodies make, the better—but do collagen supplements work? While there are not a ton of studies looking into the efficacy of collagen supplements as of yet, there are several that show very promising results.

These studies have shown that skin does in fact become more elastic with continued use, bones become denser and the overall hydration of the body is improved.

For example, in one study, 75 women, aged 35 or older, were split up into two groups. Over the course of 12 weeks, one group was given 2.5 grams of collagen peptides (combined with vitamin C, biotin and several other nutrients), while the other group was given a placebo. The group given the collagen peptides had significantly improved skin hydration, elasticity and skin density as compared to the placebo group.

Similarly, in another study, some participants were given 1000mg of a low molecular weight collagen while others were given a placebo. Skin hydration and elasticity was significantly higher in the group receiving collagen after 12 weeks than in the placebo group.

In yet another study, in which researchers looked specifically at eye wrinkles, 114 women age 45-65 were given either 2.5 g of a bioactive collagen peptide or a placebo. The women who were receiving the collagen once again showed significant reduction in wrinkles as compared to the placebo group.
These studies indicate that collagen can indeed improve skin through plumping and minimizing lines.

There are also several studies, such as this one, that indicate that collagen can also help to ease arthritis and joint pain. Given this evidence, it does seem that collagen supplements do indeed work.

How to Get the Most Out Of Your Collagen Supplement

When choosing a collagen supplement, there are few things to consider to ensure you’re getting the most out of your supplement.

For one thing, you want to find high quality collagen that allows for maximum absorption. Collagen peptides, such as marine collagen peptides powder, work really well with our digestion because they are comprised of shorter chains of amino acids—thus making them more easily absorbed into the body than other types of collagen.

You’ll also want to consider that collagen supplementation is a long game commitment. Remember collagenase? That pesky enzyme that destroys collagen? Well—your body will continue to produce that forever. Therefore, you’ll want to continue taking your marine collagen supplements forever, too, to counteract the effects. Taking collagen supplements can’t hurt you. Just be sure to take the appropriate dose as recommended on your supplements.

What Else Can You Do to Improve Your Collagen?

In addition to supplementing with collagen such as marine collagen peptides powder, there are other things you can do to support healthy skin and joints.
As mentioned before, the body uses amino acids to produce collagen.

These amino acids come from proteins. Therefore, being sure to incorporate plenty of protein from fish, eggs or beans into your diet will be helpful for maintaining beautiful skin and healthy tendons and joints.

Vitamin C is also essential for collagen production, so be sure you get plenty of fruit and vegetables that are high in this nutrient.
Furthermore, you can incorporate natural sources of collagen into your diet! Eat plenty of bone broth, and always eat your fish skin!

Should You Supplement?

Collagen supplementation certainly won’t hurt you and could very well help.
There is evidence that collagen supplementation supports healthy, youthful skin. Supplementing may help your body maintain strong levels of collagen, thus helping to hydrate your entire body and plump your skin.

If you choose to supplement with collagen, just remember that healthy skin and body also requires a healthy diet that includes lots of vegetables and protein.

The Dangers of Gluten: Why You Should Avoid It


Gluten is a protein that is found in wheat, barley, and rye.

For some people, gluten can be extremely harmful and cause health problems like Celiac disease. Others may not have any health issues with gluten, but still choose to avoid it because they feel better when they do. If you are thinking about cutting gluten out of your diet, here are some reasons why you should consider it too.

Gluten and digestive problems

If you have Celiac disease, gluten will damage the lining of your small intestine and prevent it from absorbing nutrients properly. This can lead to a host of other health problems, including malnutrition, anemia, osteoporosis, and even cancer.

Have you ever noticed that you feel tired and bloated after eating a lot of bread or pasta? That’s because gluten is actually causing inflammation in your body

Although serious, Celiac disease is relatively rare, however even if you don’t have Celiac disease, gluten can still cause digestive problems like bloating, gas, inflammation, and diarrhea, and make conditions such as leaky gut even worse. Have you ever noticed that you feel tired and bloated after eating a lot of bread or pasta? That’s because gluten is actually causing inflammation in your body. This can lead to fatigue and brain fog.

Gluten and disease

Autoimmune diseases are conditions where your immune system attacks healthy cells in your body by mistake. Some research suggests that gluten may play a role in triggering or worsening autoimmune diseases like rheumatoid arthritis, Hashimoto’s thyroiditis, and lupus. If you have an autoimmune disease, cutting out gluten should be high on your list to help manage these conditions.

There is a growing body of evidence that suggests there is a link between gluten and mental health problems like anxiety, depression, and schizophrenia. This may be due to the fact that gluten can cause inflammation in the brain which could make symptoms worse. Mental health problems are complex by nature, however improving overall nutrition and reducing gluten can be an important part of recovery.

Even though gluten is hard to avoid, fortunately there are so many gluten free food options now, that cutting out gluten is easier than ever. And, with all of the health benefits, it’s definitely worth it!

The Truth about Vitamin B12: What It Is, and How to Get Enough


You’ve probably heard that Vitamin B12 is important for our health, but do you know why?

This essential nutrient is responsible for a wide range of functions in the body, from keeping our energy levels up to maintaining healthy DNA. A deficiency in Vitamin B12 can lead to some very severe health problems, so it’s important to make sure you’re getting enough. In this article, we’ll take a closer look at what Vitamin B12 does, how common deficiencies are, and ways to get more of this vital nutrient into your diet.

Deficiencies in B12 can lead to fatigue, brain fog, hormone imbalance, depression, physical disability and even death!

Vitamin B12 is essential for the proper function of our nervous system. It helps to keep our energy levels up and aids in the production of red blood cells. B12 is also involved in the synthesis of DNA, which makes it critically important for cell growth and development. Deficiencies in B12 can lead to fatigue, brain fog, hormone imbalance, anemia, depression, physical disability and even death!

Vitamin B12 deficiencies are becoming more prevalent, and they are also much more common in certain groups of people such as vegans and vegetarians. The reason they are at a higher risk for B12 deficiency is because this vital nutrient is found only in animal products. Elderly people are also at an increased risk, as our bodies absorb less B12 as we age.

How do we know if we are B12 deficient?

Due to the vast array of symptoms that B12 deficiency can exhibit, making the connection can be difficult at first. Some people will have unexplained fatigue and weakness, or they may start to experience mental health issues that they never have previously. Sometimes it will represent as anemia, where the red blood cell count becomes very low which prevents enough oxygen form reaching the organs and other parts of the body. It’s important to take symptoms seriously and check if there is a B12 deficiency.

How can we test for B12 deficiency?

The most common test for B12 is the Serum B12 test which will essentially tell you how much B12 is within your blood stream. However, this test alone is not enough to establish or rule out a deficiency if symptoms are present. The serum B12 test only tells you how much B12 is in your serum, not if the B12 is being absorbed and utilized by the body, which is far more important.

The best way to know for sure if you have a B12 deficiency is to ask your doctor to test for both Methylmalonic Acid (MMA) and  Homocysteine. If either one or both of these tests are high, this is a strong indication of a functional deficiency in B12 and you may have pernicious anemia. Pernicious anemia is the autoimmune form of B12 deficiency and means the person is not effectively absorbing B12.

Intrinsic Factor

This is generally due to a lack of Intrinsic Factor which is a protein in the stomach that makes it possible to absorb B12 effectively. In these cases, a person will require B12 injections as their body does not have enough Intrinsic Factor to sufficiently absorb and utilize the B12 that they are consuming through their diet or supplements.

So now that we know a little more about what B12 is and why it’s so important, let’s talk about how to get enough of this vital nutrient. The best way to get Vitamin B12 is through animal products such as meat, fish, poultry, eggs and dairy. If you are vegan or vegetarian, you can still get B12 through injections or supplementation, but if you have any of the symptoms of B12 deficiency, it is best to consult with a doctor or holistic medical professional who can properly test for this.

B12 is critical to our overall health and deficiencies can lead to severe disease if left untreated. The good news is that B12 is usually easy to get through diet or supplementation, so help spread the word!

Leaky Gut Syndrome: What Is It and How Can You Treat It?


Leaky gut syndrome is a condition that affects many people, but what is it, and how can it be treated?

In this article post, we will discuss what leaky gut syndrome is, the symptoms of leaky gut, and how to treat it.

What is Leaky Gut?

Leaky gut syndrome, also known as intestinal permeability, is a condition in which the intestinal barrier becomes damaged, leading to the leakage of toxins and bacteria into the bloodstream. This can cause a variety of symptoms, including bloating, gas, diarrhea, constipation, joint pain, and skin problems. Fortunately, there are several ways to treat leaky gut syndrome. These include dietary changes, probiotics, and supplements.

Leaky gut syndrome occurs when the barrier between the intestines and the bloodstream becomes damaged.

Leaky gut syndrome occurs when the barrier between the intestines and the bloodstream becomes damaged. This can allow toxins and bacteria to leak into the bloodstream, causing an allergic response which leads to a variety of unpleasant symptoms.

The most common symptoms of leaky gut include bloating, gas, diarrhea, constipation, joint pain, fatigue, weight gain, and skin problems. In addition, leaky gut can also limit the absorption of vital nutrients from your diet, and can lead lead to deficiencies and the health issues associated with these.

How do you treat Leaky Gut?

One of the best ways to treat leaky gut is through changing your diet. Dietary changes involve avoiding foods that trigger inflammation, such as heavily processed foods, sugar, dairy, gluten, and alcohol. In addition, it is important to eat plenty of gut-healing foods, such as bone broth, fermented foods, and probiotic-rich foods.

Supplements can also be helpful in treating leaky gut syndrome. These supplements include probiotics, glutamine, zinc, and collagen. Probiotics are live bacteria that help to restore the gut flora and support a healthy digestive system. Glutamine is an amino acid that helps to repair the intestinal barrier. Zinc is an essential mineral that supports a healthy immune system and helps to heal the gut. Collagen is a protein that supports gut health and healing and can be either beef or marine collagen.

If you think you may have leaky gut syndrome, it is important to discuss this with your doctor, or a natural health professional as they can help to diagnose the condition and recommend the best course of treatment for you. With the right treatment, leaky gut syndrome can be managed and healed.

The Ketogenic Diet: Health or Hype?


The ketogenic diet is all the rage right now. But does it really work? And is marine collagen compatible with the diet?

There are a few things to consider before starting any diet, and the ketogenic diet is no different. The first thing you need to think about is your goals. What are you hoping to achieve by following this diet? Do you want to lose weight? Are you looking to improve your overall health? Or are you hoping to manage a specific health condition? Once you know your goals, you can start to research whether or not the ketogenic diet is right for you.

What is the Ketogenic Diet?

The ketogenic diet is a high-fat, moderate protein, low-carbohydrate diet. This means that you will be eating mostly fat and very few carbs.

When you eat far fewer carbs, your body begins to burn fat for fuel. This can put your body into a metabolic state called ketosis. In this state, your liver turns fat into small energy molecules called ketones, which your brain and other organs can use for energy. This can be a difficult adjustment for some people, but it is important to remember that your body will adjust over time.

Switching from Carbs to Fat

One of the most difficult aspects of this diet happens in the first few weeks, as our body switches from getting energy from carbs (sugar) to fat, and this will often be experienced as excessive tiredness and brain fog. This feeling does pass though, and many people come out the other side feeling better, with increased energy.

The ketogenic diet has also been shown to be effective for weight loss in numerous studies, and has been shown to improve metabolism, and insulin response which can make it an effective option for those suffering from type 2 diabetes, or people who are pre-diabetic.

Studies have now shown that the diet can have benefits including a lowering over overall cholesterol, improvement in heart disease risk factors, and can even be effective for people suffering from cancer and Parkinson’s disease.

But is the ketogenic diet compatible with marine collagen? Absolutely! Marine collagen is high in protein, and has zero carbs so fits perfectly within the perimeters of the ketogenic diet.

So, should you try the ketogenic diet? Ultimately, the decision is up to you. But by doing your research, you can make an informed decision about whether or not this diet is right for you.
