The Health Virtues Of Collagen: Sources, Uses And Benefits

For those who have visited other posts on this site, you have probably come across some topics in reference to “ageing”. The most in depth article that has covered that sub topic as it regards to health and wellness is one titled “The Short Answer To Aging: Lengthen Your Telomeres.” In retrospect, I feel a bit re-missed that I overlooked a very important protein in which I failed to even mention a single blurb on in that particular article. That would be collagen.

When I wrote the piece on telomeres, I recall seeing some mention of collagen in some of the researched material but, did not get it into the finalized article before it was published.

Well, thanks to being more informed on this subject in recent weeks, via Dr. Jennifer Daniels radio program, I decided to do some deep research on why collagen is such an important protein and present my findings.


What Is Collagen?

Collagen is a protein based constituent in the connective tissues of the body. In mammals, this is the most abundant protein accounting for 25 to 30% of the bodies total content thereof. It is one one of several fibrous structural proteins. Collagen’s function in the body provides a different purpose than globular based proteins such as enzymes which are soluble and more geared for supporting regulatory functions.

Collagen is made up of fibers known as collagen fibers and have extracellular modalities that support most tissues. It also plays a significant role in building and strengthening cartilage, ligaments, tendons, bone and teeth as well as fortifying blood vessels and elasticity of skin. In addition, collagen has a presence in the in the cornea and lens of the eye in crystalline form. source

There are 28 types of collagen in the body and each one plays a different role in organ health.

Two of which provide a couple vital functions: One type of collagen provides structural maintenance for the skin. Another provides support in cartilage to aid in keeping joints strong.

Video – More on the different collagen types:

Collagen is made up of 4 different amino acids:

  1. glycine – A non-essential amino acid (meaning the body can produce it on it’s own without including it into a diet or supplementing). It is used to build muscle tissue, convert glucose, maintain a healthy nervous system, a healthy digestive system and has been shown to provide antioxidants that protect from certain types of cancer
  2. proline – An amino acid vital for the production of cartilage and collagen. It aids in the flexibility of muscles and joints and reduces sagging and wrinkling of skin caused by UV exposure and normal aging.
  3. hydroxyprolineAnother non-essential amino acid that is produced from other amino acids in the liver.
  4. arginineAnother non-essential amino acid that occurs in proteins and is involved in the urea cycle and in the synthesis of creatine.

Causes and Symptoms Of Collagen Deficiency

Since roughly 30% of bodily proteins are made up of collagen, it is of no coincidence that a deficiency in this vital protein can lead to a number of health issues. On that note, lets look at some symptoms and causes that are indicative of this inadequacy:

Accelerated aging of skin/wrinkles:

Collagen synthesis/production diminishes as we age. Since collagen comprises 80% of the protein in our skin, the declining levels that occur as we age are the prime accountable factor for the loss in smoothness, firmness, elasticity and buoyancy as we get older.


It is suggested that the reason for the fat deposits that make up cellulite and press their way into the skin tissues (causing the wavy/sagging lines) is due to weakened collagen fibers.

An estimated 85 to 98% of post-pubertal females have cellulite. Very little scientific research has been undertaken as to the physiology of it’s pervasiveness in women. In the last 30 years, only a few dozen peer reviewed articles have been published.

However, a long term clinical study was conducted, involving women given bioactive collagen peptides (BCP) for a duration of 6 months. The BCP treatment led to a significant decrease in the density of cellulite and waviness of skin in participants of normal weight . To a lesser degree, the overweight participants experienced a decrease in cellulite as well.

Damage from sun (UV over) exposure:

This is referred to as “photoaging” (as opposed to chronological or natural aging) and is a consequence of overexposure to ultra violet sunlight. Photoaging is caused partly by the damage incurred to the skin’s connective tissues and by reduced collagen synthesis. read more here


Joint pain

Deficiency in the cartilage (which hold joints together) can have an affect on the durability of joints causing stiffness that leads to joint pain.

Fragility of bones: 

An estimated 6.8 million bone fractures occur alone in the United States as stated by the American Academy of Orthopedic Surgeons. The estimates suggest that each person will sustain 2 fractures over the course of a lifetime.

Collagen accounts for 90% of the bones’ organic components. This is the vital living tissue of the bone and is crucial to reinforcing the bone’s ability to sustain higher impact and flexibility. When collagen is diminished (in particular Type 1 collagen) the strength of the bones are greatly compromised. read more here

Muscle aches:

Collagen is a medium for the cementing of muscle fibers. Frequently aching muscles are a sign that you could likely be collagen deficient.

Problems with blood pressure:

A deficit in collagen can also affect blood vessels. Which include, recurrent headaches, chest pain, dizziness and fatigue.

Loose teeth (tooth aches)

Collagen aides as a foundation for binding teeth to gums. The lack of thereof can cause the loosening of teeth and eventual impairment, thus being a probable sign that you are collagen deficient.


It has been hypothesized that an invasive/metastasizing cancer could be systemic (secondary) to a degeneration of connective tissues. In particular, diminishing of the connective tissue of the basement membrane, which underlines the epithelium (cellular covering of internal and external surfaces of the body) of the dermal and mucosal (mucous membrane) tissues. It is suggested that the causation of this could be a deficiency in vitamin c.

Furthermore, this vitamin c deficiency is the causal factor due to the liquefaction of collagen in the epithelial and connective tissues. This then, results in a breakdown in the systematic arrangement of cellular structure that could be a harbinger for malignant/metastasizing cancer. read more here

Some Notable Benefits Of CollagenFile:Wavy collagen.jpg

Here are some beneficial factors, in addition to mitigating the causes and symptoms aforementioned above, that can be remedied with collagen.

  • Revitalize hair, skin and nails
  • Fortify skin elasticity and reduce the signs of aging
  • Improved digestion
  • A substantial source of protein

Natural Remedies For Improving The Uptake Of Collagen

Now lets explore some viable options for getting this important protein into our bodies to either heal or preemptively address the symptoms and causes of collagen deficiency mentioned above.


As with any regimen for implementing improved health and wellness, supplementation is probably the easiest (less time consuming) way to go. When it comes to getting collagen into the body and or boosting collagen production/synthesis in the body there are mixed opinions as to the results. Some say they have yielded positive outcome and others are more skeptical.

Either way, here are the supplements that seem to get the most positive sentiment:


Image result for gelatin

Gelatin has been known for nearly a century to to provide improvements to hair, skin and nails. It is also known as “cooked collagen” and is considered to be a super-food that protects from inflammation and has anti-aging properties.

Gelatin contains the important amino acids (especially rich in glysine and proline) that are absent in the standard American diet. Gelatin is low in methionine which is a proteinogen/essential amino acid and prevalent in lean muscle meats.

Although methionine has many virtuous benefits, it is also claimed that an over consumption of these “methionine” rich meats can have inflammatory consequences. So, If one consumes these lean muscle meats daily it would probably be all the wiser to consider adding gelatin or another source of collagen to better balance your diet.

Mango-Lime gelatin gummy recipe:

Here is a simple recipe that contains 4 basic ingredients:

  • 1 large mango, peeled and cut into chunks;
  • 1/3 cup lime juice;
  • 1/3 cup water;
  • 4 tbsp gelatin powder;

read more here on preparation.


Precautionary side effects to be aware of when supplementing with a gelatin powder:

If you are using this medium of supplementation, it is important to take into consideration that gelatin has been purported to cause digestive issues, including: constipation and bloating. Consuming too much too fast can overwhelm the gut, leading to those repercussions. It would be a wise choice to make sure you drink enough water and take digestive enzymes when supplementing with gelatin. read more here

Vitamin C:


Vitamin C is crucial for the secretion of collagen. It is an essential nutrient that helps to provide the body’s ability to to uptake collagen. When collagen is being produced, a number of events occur inside and outside the cell. Vitamin C activates inside of the cell to produce proline and lysine.

Since the body must continually produce collagen, it is important to have adequate levels of vitamin C to complete this process, due to the fact the vitamin C is constantly being used up or destroyed during the cycle. In short, without Vitamin C this action is disrupted. Vitamin C is not a collagen source in and of itself per se, but is a vital component in the building process of collagen and is an essential nutrient, which is to say, the body cannot produce it on it’s own. source

Collagen Hydrolysate:

File:CSIRO ScienceImage 293 Cells Interacting With Collagen.jpg

Also known as Hydrolyzed Collagen, this powdered supplement is highly concentrated with the amino acids glysine, lysine and proline. It is beneficial in restoring the synovial fluids (a clear fluid that serves as a lubricant for joints and tendons) between the joints. These amino acids are found in lower amounts in other protein drinks. Due to it’s molecular structure, hydrolyzed collagen is more easily digested. The absorption time is about 30 minutes. source


Collagen boosting supplements for bone fractures:

When a bone is fractured, the tightly bound stands of collagen in the mineral formation of the bone are ruptured yielding a release of oxygenated radical metabolites. These free radicals are the culprit for the inflammation suffered causing a further breakdown of collagen as a result of the fracture. Here is a list of supplements that can help suppress the repercussions of these free radicals that deplete collagen integrity and help to speed healing:

Note: These items are co-factors, which is to say they do not contain collagen but will aid in the synthesis of collagen and (or) stabilize it.

  • Vitamins E and C (mentioned above), lycopene, and alpha-lipoic acid – Research has suggested that these can reduce the stress incurred by free radical damage and improve the healing of fractures.
  • Copper – Copper supports the formation of bone collagen and is imperative to the healing process. The body’s  dependency on both copper and zinc rises in accordance to the severity of the fracture. Read more on copper here
  • Silicon – For some time now silicon in it’s bio-active form “silica” has been known to be an effective co-factor for the synthesis of collagen.
  • Vitamin K – As far back as 1960 it has been noted that vitamin K has an advantageous effect on fracture healing and has a profound effect on all collagen tissues, chiefly bone tissue. In researched findings, vitamin K is appropriated to the site of fracture resulting in markedly depressed circulating levels of vitamin K in fracture patients.


Collagen boosting foods:

There are a number of food sources that can help in restoring collagen in the body. Some of these foods are merely co-factors that aid in the production of collagen (which do not contain collagen) while others are actual collagen containing foods.

Co-factored food sources:

Image result for Collagen promoting foods

  • Dark green vegetables: Veggies such as spinach, kale and cabbage are benefactors in a daily diet in that they contain the anti-oxident lutein. Recently, French researchers have revealed the claim that lutein fights wrinkles by way of hydrating skin and promoting elasticity. To get the optimum results, it is said that it is required to consume the equivalent of 10mg of lutein, which adds up to 4oz of spinach or 2oz of kale.
  • Beans: Beans aid in producing an important anti-ageing element called hyaluronic acid. A good target would be to aim for at least two table spoons of either butter or broad beans.
  • Red pigmented fruits and vegetables: Due to the presence of lycopenes (a carotenoid and phytonutrient rich anti-oxidant that protects against degenerative diseases) in this food source, the anti-oxident properties help promote the production of collagen. Researched studies have shown that these anti-oxident/phytonutrient rich food types protect the skin from UV damage.
  • Vitamin C: As mentioned previously, vitamin C is a substantial co-factor for the production of collagen.

List: the top 10 vitamin C rich foods.

  • Prunes and blueberries: Free radicals are one of the biggest culprits of ageing via the fact they attack the cohesion of healthy skin tissue. Anti-oxidents are the prime counterweight protection against this assault and prunes and blueberries have among the highest amount in this regard. Eating 5 or 6 prunes or a small bowl of blueberries daily would be a good RDA.
  • Green/black olives, cucumbers and celery: These vegetables are dense in sulfur content, which is another important element in the production of collagen.
  • Raw carrots, fresh cantaloupe and baked sweet potatoes: Working in confluence with sulfur, vitamin A is viable booster for collagen production and these are near the top of the list in vitamin A content.
  • Manuka Honey: This honey is native to new Zealand and has unique healing properties. It has been used by the indigenous people (Maori) of that region for centuries. There are claims that this honey can restore and rejuvenate skin when used topically. Because of it’s anti-oxident properties, it can also proliferate the formation of collagen and thus, simulates skin cell renewal.


Collagen rich food sources:

It’s important to note that only animals have collagen. So, for vegans and vegetarians the co-factored foods mentioned above are going to be a source for helping the body restore collagen and are not a direct source of collagen in and of themselves.

Dr. Jennifer Daniels, on her radio show on May 13, 2018, spoke extensively about how to get the best sources of collagen into your diet and how there is misnomer as to how many websites list many of the co-factored foods (cited above) that top the lists, but yet have no collagen content chiefly because most of them are plant based. Listen here

The animal (and marine) based foods listed below (according to my findings in research) are the best known direct sources of collagen.

Pigs feet: 
Also called “trotters”, pig feet are extremely dense in collagen. They are considered by many to be a delicious and favored food. Nutritional experts say that it can be added to our own collagen and assimilate as raw material for collagen synthesis in the human body.

In New York, a Japanese restaurant that opened back in 2008 drew a lot of buzz for featuring pig’s feet dishes on 33 of 39 of their menu items. The owner of the establishment, Himi Okajima, stated that pigs feet are rich in collagen. He went on to point out that collagen helps to retain hydration in the body. He claims that if people in their 30s began to consume collagen they would look younger by their 40s. Okajima also started a chain of restaurants in Japan that features collagen based cuisine. read more here

Pigs ears:

Pigs ears are probably the most collagen dense food you can add to your diet. There are many recipes one can look up including some here and also the video below:

Chicken Feet:

Chicken feet are especially rich in collagen and in particular the chicken claws. This was revealed in study conducted by the Faculty of Veterinary Science Chung-Hsing University in Taiwan. source

Video – chicken feet recipes:

Cows feet:

Yet another bountiful collagen source, cows feet are most commonly served for the culinary purpose of making stock and stews.

Videos – cows feet recipes:

Bone broth:

Bone broth is one of the more well known collagen dense dishes and is probably the simplest to prepare:

Video – bone broth recipe:

Fish head soup:

Once again, another extremely solid source of collagen. This source cites fish head soup as being a great booster for his kids during school exam periods and also states that it increases the growth of milk production for breast feeding mothers. see recipe

Video – more fish head soup recipes:

An important factoid to work into this equation when considering getting collagen from animal (marine) sources:

You will get very little collagen from the lean meats of the animal and marine sources mentioned above (or any animal/marine sources for that matter). Most of the collagen resides in the joints, tendons, organs, fat and skin tissue (essentially the connective tissues). More on this is explained in the video below:


In researching and writing this piece, I had 3 primary takeaways I would like to share:

1. Supplementation and side effects:

The best substantiated findings I came across in putting this article together as to the side effects of supplementation was the digestive issues that can manifest from products like gelatin powder. It is true that these supplement powders are highly processed but, a lot of the data regarding the side effects seems to be somewhat trivial or anecdotal.

If you do some poking around the web you will find claims such as, high calcium levels (which can lead to nausea, constipation, vomiting and abnormal heart rhythms), Hypersensitivity and leaving a bad taste in the mouth. example here

Since supplementation is usually the easiest and quickest method of delivery when it comes to getting nutrients into the body it would probably be wise to start with low doses monitor how your body responds and work your way up to an optimum dosage thereafter and as mentioned above (pertaining to gelatin supplementing), drink plenty of water and take a digestive enzyme like hydrochloric acid to help break down and assimilate the high protein content.

Also, on the subject of supplementation and side effects: I thought this would be as good a place as any to implore you the reader to inform your doctor/practitioner/health care provider if you are interested or planning on using these supplements, as it is always wise to keep him/her informed (especially if you are on medications).

2. Assessing Co-factored food sources:

Most of these food sources are ones that I have written about in several other posts and they do provide tremendous nutritional value. However, since none of these foods contain collagen, you would probably have to consume ridiculously vast amounts of them daily (especially if you are a vegan/vegetarian) to get enough into your system to convert it into enough collagen to do any good. So, I would suggest that it is likely not realistic or sustainable to rely on those foods alone.

Taking the collagen supplements mentioned above or a collagen rich animal protein directly from the animal in conjunction with the plant based foods (fruits, nuts and vegetables) would probably be best option.

Again, if you are a vegetarian, probably the best you can do in addition those co-factored foods is to make sure you  are getting enough vitamin C to help in the stabilization of the collagen that is currently active in the body.

One of the most debated topics in terms of nutrition is whether a plant based diet or a animal based diet is best. I’d suggest that the animal based diet wins the argument in the case of collagen proliferation and restoration pretty easily.

3. Collagen rich food sources (directly from animal/marine source)

If you are like me, you are saying to yourself that these food sources in the videos above do not have the appetizing appeal that lean meats from these animals do. Well, the truth of the matter is, that’s where all the heavy artillery is found if you are serious about combating a collagen deficiency.

These foods (dishes) have been consumed in eastern diets for centuries and there has been somewhat of a falling away from this in western culture within the last century or so. I doubt that it is a mere coincidence that the people who partake of these dietary habits typically look younger and are overall, healthier.

However, Something worthy of mention is that we all metabolize differently and taking that into account is worth being mindful of, in my opinion, in reference to how much of these foods you should consume. As individuals, some may not be able to assimilate the high protein content as easily as others. I cover this more in my post What is a Metabolic Typing Diet? Finding Your Metabolism Specific Blueprint.

Final thoughts

Much of the information I attained in learning about collagen while researching for this piece has brought revelations that has changed my way of thinking on a couple things. One of them is “pork”. I gave up eating pig some time ago due to some held beliefs that it is not the most healthy form of animal protein. Now, after what I have learned here as to the importance of a collagen rich diet, It looks like I may have to second guess myself on this one.

Also, I brought home some braised chicken for dinner tonight and normally I would remove all the fat, gristle and skin before consuming, but with the new found knowledge that most of the collagen is in those parts (tissues cartilege ect…), I instead put myself on gag-reflex alert and decided to consume all of the chicken except the bones. Surprisingly, it wasn’t that bad and actually pretty good with the rest of the meat. So, a step in the right direction and maybe the pigs ears, trotters, chickens feet and fish head soup will eventually make it onto my menu next.

Best of health to you

  1. Thank you for researching this topic. It’s extremely comprehensive and informative. Prior to reading your post, I had no idea there are so much more to collagen than I know. You mentioned chicken feet, pig ears, and pig feet recipes. My parents always say eating those things can help you get beautiful and radiant skin, I never believed them. In fact, in my culture, people love these foods, but I never find them appetizing. After reading your post and watched some videos, I think I might give them a try. Now who does not want beautiful and radiant skin? I know I do. Thank you for the awesome post. I am much more informed about collagen now. Keep up with the good work.

    1. Thanks once again for chiming in Hong,

      I was very interested in getting your thoughts on this particular post because i know you grew up in China and figured you could speak in familiarity to these dishes. When researching this topic i found out that these are the collagen rich foods that people from where you come from (and many others in eastern culture) have had in their diet for centuries and I can certainly see why. I have some Filipeno co-workers who enjoy fish head soup. They say it’s really tasty. It’s gonna take some courage for me to give that one a try. I’ve given a lot of thought over the last few days to just how one could concoct some recipes that would be more appetizing. I was thinking that, for stews/soups like chicken stew or soup (for example) maybe make the broth from the most collagen rich parts of the chicken like the feet, joints, cartilage and bones and then you could then add your favorite vegetables and the more popular items like the breast, leg and thigh meats and have a collagen dense stew/soup that is very tasty as well. Same type of principal with the pork and fish. I think that may be worth a try. In fact I wouldn’t be surprised if the recipes are already out there. My mom has made chicken bone broth soup for years. She recently reminded me that she used to make it for us back when I was growing up. She knew it was great for helping to prevent colds and flu.

      As always, bless your heart for adding another wonderful comment,

      talk soon, Brad

      1. In our culture, people consume a lot of these collagen rich foods. I will be honest that some dishes are ok, some gross, lol, some are actually tasty. It all depends on how you make it. I am not sure if you have even been to Chinatown, they have roasted sliced pig ears, duck wings, and chicken feet that actually taste good. Pig feet are never a thing for me. Tried it before and will never eat it again. Making your own collgen rich foods, such as the soup is the best way to get the most amount of college out the foods you consume. When you get a chance to go to Chinatown, I hope you try out the foods I mentioned; I think you will like them. Good luck making your soups.

        1. I think there is a reason that the people in your culture overall look younger and have a lower mortality rate than those who born and raised in the western hemisphere where the standard american diet is so much more pervasive. Although pig (ears and feet) derived dishes are pretty popular in the south and have been for a long time. Consuming collagen rich foods are big factor as i have learned in recent weeks studying this topic. I came upon the information listening to Jennifer Daniels’ radio show a few weeks ago where she covered (in depth) the importance of collagen and deficiency is the causation for a lot of degenerative issues. So I was compelled to learn more and thought it would be a great topic to write about. I’ve had chicken for dinner a few times over the last week (including tonight) and I now eat everything except the bones (skin fat gristle and all) because I know that is where the most nutrient (collagen) dense part of the bird is. I believed for so long that the lean meaty part of the animal was the healthiest. I’ve since learned otherwise. And yes i do want to get around to experimenting with the soups and poke around the web for some tasty recipes.

          Thanks for sharing your experience with these foods.

          Blessings and talk soon,Brad

  2. Great article packed with useful information. Definitely going to add gelatin to my diet. Thank you for doing the research on this subject. I will try some of the remedies in your post. Good work Brad. Looking forward to your next post.

    1. YW. Thanks for taking the time to read and comment. I’m going to make concerted effort to add more collagen to my diet as well.

      Bless you for the comment, love ya, Brad
