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!

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.

What is Collagen Good for?


Collagen, it’s the most common protein in the body, providing structure to your skin, and strength to your muscles, ligaments, and bones.

Many people are becoming aware about the importance of collagen for overall health and have sought ways to increase collagen through both food choices and supplementation. In this article, we will discuss the role that collagen plays in the body and the effects supplementing with collagen can have.



Collagen is a structural protein made up of amino acids. Almost every part of our body uses collagen in some way, and as we get older our natural collagen production steadily decreases. Our bodies are in a constant state of repair and regeneration, in which collagen plays a crucial role.

But as our collagen production decreases, this process becomes more challenging, we don’t feel as energetic as we did when we were young, our skin can become dry, showing fine lines and wrinkles, and injuries take longer to heal.

Although aging is inevitable, there are ways to slow this process down by stimulating our own collagen production, consuming collagen rich foods and by taking high quality collagen supplements.



Did you know that there are 28 different types of collagen in the body? Although this is true, Type I collagen is by far the most prevalent accounting for approximately 90% of all the collagen we have.

Type I collagen is critically important for skin elasticity, hydration and appearance, hair quality and abundance, and nail quality and growth. It is also important for our muscles, ligaments, bones, and even digestion.

In addition to Type I collagen, Types II, III, and IV are also prevalent and required for maintaining and repairing cartilage, vital organs like the heart and kidneys, our veins, blood vessels, and eyes. The essential role that collagen plays in our bodies has been studied extensively, and in addition collagen supplementation has been shown that it can lead to dramatic health improvements.

However, for collagen supplementation to be effective, it needs to be taken in high enough quantities, and also needs to be in a form that is easily absorbed by the body. This brings us to collagen peptides.



Collagen peptides are collagen proteins that have been broken down into smaller pieces making them more bioavailable for the body, or in other words, easier to use. This is important because the more bioavailable the collagen proteins are, the less you need to take to achieve results. How is this achieved? Through a process called Hydrolysis.

Hydrolysis uses water to break down the collagen proteins amino acid chain down to their smallest and most usable form, without using toxic chemicals, and what remains are hydrolyzed collagen peptides, the good stuff! This incredible process is how most collagen peptide supplements are made. However not all collagen supplements are created equal as there are vast differences in both collagen sources and methods of hydrolyzation.



Most collagen supplements are made from either beef collagen or fish collagen. However, when it comes to bioavailability, fish collagen peptides are up to 50% more bioavailable than beef collagen peptides. In addition, marine collagen peptides are a much higher source of Type I collagen, the most abundant type of collagen in the body, and utilized by numerous processes affecting both our health and appearance.

Hydrolyzed marine collagen peptides are also far easier to dissolve into liquids, which makes it a more versatile supplement as its relatively simple to mix into any drink or meal.



SKIN:  Collagen helps to rehydrate the skin and increases the production of new skin cells. Collagen can also reduce fine lines and wrinkles leading to smoother and younger looking skin.

HAIR:Collagen can slow down and reverse hair loss, increase scalp coverage, and will often lead to thicker and fuller hair quality.

NAILS: Collagen promotes stronger nail quality, less chipping, and faster growth.

BONES:Collagen helps strengthen and protect bones, making them less brittle, and faster to heal if damaged.

MUSCLES:Collagen can help with increasing muscle mass and overall strength.

GUT HEALTH: Collagen is important for both digestive processes and has been shown to help with intestinal repair.



When it comes to supplementing with collagen, the amount you need is higher than many people realize. This is not a supplement that you can take a couple of capsules a day and see dramatic improvements. Collagen is a food, super high in protein, and packed with amino acids.

Marine Collagen Peptides Powder for example, is the most bioavailable collagen available – however studies have shown that to achieve maximum results, you need to take on average 10 grams per day, that’s 10,000mg!

Fortunately, due to hydrolyzation, most marine collagen peptide powder will dissolve in liquid, so adding this amount to your morning coffee or mixing it into food is easy. Marine collagen is also totally carb free, so it won’t spike your blood sugar and your diet.



As collagen is so beneficial to humans in general, almost anyone can take and benefit from collagen supplements. There are exceptions, however. If someone is allergic to fish for example, taking marine collagen is a bad idea and could lead to a reaction. In addition, pregnant women should ask their doctor before adding collagen or any other supplement to their diet just to be extra safe.

It is also worth noting, collagen is not a vegan product as it only comes from animals, although some vegetarians may consider it acceptable depending on their individual approach. If you are adhering to a Paleo or Keto diet, you are in luck as collagen fits in perfectly with these. Marine collagen is also a good choice for those on a Pescatarian (fish) diet.



Collagen is without a doubt one of the most important proteins in our body, but what is collagen good for?

it essentially holds our body’s together, helps us move, and keeps us looking young. But as we age, our natural collagen production declines, leading to an older appearance and a less functional body.

Supplementing with collagen however, especially with hydrolyzed marine collagen peptides powder, can boost our collagen levels helping us to look younger and feel better!

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.

Marine Collagen Supplements: The Secret to Beautiful Skin


If you’re like most people, you want to have beautiful skin that looks young and healthy.

But as we age, our natural collagen production decreases, leading to wrinkles, dryness, and a loss of elasticity. Thankfully, there is a way to supplement our collagen levels and keep our skin looking its best: marine collagen supplements! In this article, we will discuss the importance of using marine collagen for the creation of beautiful skin.

What is Collagen?

First, we need to understand what collagen actually is. Collagen is the most abundant protein in our body, accounting for 25-40% of all protein within the body. Collagen is critical in the formation, strength, elasticity and regeneration of connective tissues in the body, such as skin, nails, tendons, ligaments. After the age of 20, a person produces about 1 percent less collagen in the skin each year. As a result, the skin becomes thinner and more fragile with age.

Marine collagen is especially beneficial for the skin, as it contains high levels of Type I collagen which is known for its anti-aging properties.

Studies have shown, that by supplementing with marine collagen, we can replenish our supply of this important protein, and help to reduce the visible signs of aging. Marine collagen is especially beneficial for the skin, as it contains high levels of Type I collagen which is known for its anti-aging properties. In addition to helping to reduce wrinkles and fine lines, marine collagen can improve the quality of our hair, and nails. It is also very beneficial to our tendons, ligaments, bones and can even help with gut repair.

Why does Marine Collagen work so well?

Marine collagen is the most bioavailable form of collagen, meaning that it is easily absorbed by the body. This makes it an ideal choice for those who want to results fast. Marine collagen will also dissolve easily into any liquid or meal, making it super easy to add to your morning routine. Simply add it to your smoothie, coffee or tea and you’re good to go!
