What is collagen and why is it important?

Protein is the structural component of collagen. In point of fact, it is the structural protein found in the greatest abundance in animal cells. Proteins that contribute to the framework or structure of your cells and tissues are referred to as structural proteins.

There are 28 different varieties of collagen that have been identified, with type I collagen making up around 90% of the collagen found in the human body.

Glycine, proline, and hydroxyproline are the three amino acids that make up the vast majority of collagen. These amino acids organize themselves into three strands, which together form the characteristic triple-helix structure of collagen.

Connective tissue, skin, tendons, bones, and cartilage all contain collagen in their respective structures. The following are some of the crucial roles that it plays in cellular processes:

tissue repair

immunological response

communication between cells and migration of cells, a process that is essential for the maintenance of tissues

Connective tissue cells known as fibroblasts are responsible for the production and maintenance of collagen. As people get older, the collagen in their bodies begins to break, fibroblast function begins to deteriorate, and the rate at which collagen is produced slows down.

Sagging skin and wrinkles are two of the telltale indications of ageing that are caused by these changes in the skin as well as the loss of elastin, which is an important structural protein.

Collagen uses

Collagen is a protein that is produced by the body on its own, and it may also be obtained through the consumption of dietary sources such as fish skin and chicken skin, in addition to collagen supplements.

The treatment of indications of ageing such as wrinkles, loss of skin moisture, and joint pain is increasingly being done with collagen products that can be taken orally or applied topically, such as face creams and supplements.

There are powdered, pill, and liquid forms of collagen that you can purchase.

You can take it as a dietary supplement, and add it to beverages (both hot and cold), and foods like oatmeal, yoghurt, and energy balls. You can also add it to a mixture of the three.

Collagen and other materials derived from collagen are also utilized by medical practitioners in the treatment of a variety of medical conditions, including wounds, burns, and diabetic ulcers.

In addition, the humectant and moisturizing qualities of collagen make it an appealing ingredient for use in a variety of cosmetic products, including serums and moisturizers.

Your body is capable of producing its own collagen. Collagen is a protein that has multiple purposes and can be found in connective tissue, skin, tendons, bone, and cartilage. It is also possible to consume it in the form of a dietary supplement, as well as find it in certain meals.

What causes collagen loss?

As you age, your collagen production naturally diminishes. In addition, collagen becomes broken and is dispersed in a more disorganised manner.

Wrinkles, dryness, and sagging skin are some of the telltale indications of ageing that can be attributed to these skin alterations. In addition, the collagen contained in the skeletal system loses its structural integrity as we become older, which results in a weakening of the bones.

Even while the breakdown and destruction of collagen that comes with ageing are unavoidable, there are some dietary and lifestyle factors that might speed up the process.

Cigarette smoking, for instance, is known to break down collagen and cause premature ageing of the skin, as well as wrinkles and a loss of elasticity.

Drinking to excess has also been demonstrated to hasten the ageing process of the skin by inhibiting the formation of collagen and causing damage to the skin’s healing systems.

Additionally, eating a diet heavy in added sugar and ultra-processed foods might hasten the ageing process by contributing to a process known as glycation. This process slows the turnover of collagen and impedes collagen’s capacity to interact with the cells and proteins in its surrounding environment.

In addition, prolonged contact with the sun causes a degradation in the creation of collagen; therefore, preventing prolonged sun exposure and protecting one’s skin with sunscreen are both important steps in the fight against the visible indicators of premature ageing.

The loss of collagen that comes with ageing is unavoidable; however, variables connected to nutrition and lifestyle, such as smoking and excessive alcohol consumption, can speed up this process.

Best food sources of collagen

Collagen is a protein that may be found in all living things, but it is more abundant in certain areas of an animal’s body, such as the skin and the joints.

The following is a short list of foods that are high in collagen:

bones, skin, and ligaments of animals, such as chicken skin and pig knuckle certain types of seafood, such as fish skin and jellyfish products made from animal parts such as bones and ligaments, including bone broth bones, skin, and ligaments of animals, such as chicken skin and pig knuckle certain types of seafood, such as fish skin and jellyfish certain types of fish

Because your body naturally creates collagen from amino acids, you may encourage the synthesis of collagen by ensuring that you consume a proper quantity of protein from foods like chicken, fish, beans, and eggs. This will help your body manufacture more collagen.

Your body needs nutritional components and other amino acids in order to produce and maintain collagen, thus those dietary components are essential.

For instance, while collagen synthesis cannot occur without vitamin C, having insufficient amounts of vitamin C or a deficiency in vitamin C might result in decreased production of collagen.

Therefore, eating a diet that is abundant in foods that are rich in vitamin C can assist support healthy collagen formation. For instance, give fruits of the citrus family, peppers, greens, and berries a shot.

Consuming a diet rich in beneficial plant chemicals may also assist improve skin health by lowering inflammation and preventing collagen breakdown. This can be accomplished by improving the skin’s blood circulation.

Collagen can be found in abundance in a number of foods, including animal skin and ligaments. A diet that is beneficial to collagen production should contain meals that are high in protein in addition to fruits and vegetables, which are high in vitamin C as well as other antioxidants and anti-inflammatory chemicals.

Are there benefits to taking collagen supplements?

According to the findings of several studies, consuming collagen supplements might provide a few advantages.

Potential skin benefits

One of the most common uses of collagen supplements is to improve the appearance and health of the skin. According to some research, taking collagen supplements may improve both the overall health of the skin and certain aspects of its appearance.

A comparison of hydrolyzed collagen with placebo treatments resulted in better skin hydration, suppleness, and wrinkles, according to a study of 19 trials that involved 1,125 participants (95 percent of whom were women) between the ages of 20 and 70.

One form of collagen that is frequently seen in dietary supplements is known as hydrolyzed collagen. This form of collagen is produced through a method known as hydrolysis. Because of the way in which this process breaks down the protein into tiny bits, it is much simpler for the body to absorb.

Taking collagen supplements has been demonstrated in a number of studies to have the potential to improve the hydration and flexibility of the skin, as well as to lessen the appearance of wrinkles.

However, it is important to keep in mind that a significant number of these research were supported by companies that manufacture collagen products, which may have influenced the study outcomes.

There is a wide range of beneficial doses of collagen for enhancing skin health that has been demonstrated in research studies; nevertheless, the majority of studies have employed 2.5–15 grammes per day for 8 weeks or longer.

Potential benefits for bones

Collagen supplements may give a few additional benefits in addition to the ability to improve some aspects of the health and look of the skin.

In one study, the effects of administering collagen supplements to 102 postmenopausal women who already possessed a reduced bone mineral density were investigated (BMD).

When compared with participants who took a placebo, those who consumed 5 grammes of collagen peptides on a daily basis for a period of one year exhibited significant increases in bone mineral density (BMD) in their spine and femur (a bone in the lower leg).

In a subsequent study involving the same group of women, researchers showed that ingesting 5 grammes of collagen on a daily basis for a period of 4 years was connected with a rising bone mineral density (BMD).

During the course of the study, the researchers discovered that the patients’ BMD grew anywhere from 5.79 to 8.16 percent in the spine and anywhere from 1.23 to 4.21 percent in the femur.

According to these findings, using collagen supplements over an extended period of time may help enhance bone mineral density in postmenopausal women, who are at a larger risk of developing osteopenia and osteoporosis than younger women.

In addition to this, one review article came to the conclusion that taking oral collagen supplements improved the symptoms connected to osteoarthritis, particularly stiffness, in the participants.

Collagen supplements may also give additional health benefits, such as an improvement in body composition in certain populations when combined with resistance training. These benefits may be obtained by taking collagen supplements.

It is essential to keep in mind that the favourable effects of consuming collagen were primarily identified in trials with elderly women who lacked adequate bone mineral density.

Therefore, the effects of collagen supplements might be different in other populations, such as men, younger people, or people who do not have a low bone mineral density.

Do collagen supplements have side effects?

Supplements made of collagen have an excellent safety profile and are not linked to any unfavourable side effects.

Nevertheless, producers of supplements frequently mix collagen with a variety of other components. In supplements created to promote the health of the skin, nails, and hair, products containing certain substances, such as herbs and high amounts of vitamins, have the potential to be harmful to one’s health.

Substances in dietary supplements, such as herbal extracts, may, for instance, interact negatively with regularly prescribed drugs, and some of these ingredients should be avoided entirely by women who are pregnant or nursing.

In addition, certain supplements that contain collagen may also contain megadoses of nutrients such as biotin, which may interfere with the results of laboratory tests that evaluate the function of the heart and thyroid.

If you take excessive amounts of these and other vitamins and minerals for an extended period of time, you may experience health problems.

Therefore, although supplements that include only collagen are not expected to have any adverse effects, it is essential to read labels and have an understanding of the potential hazards associated with supplements that contain collagen coupled with other components.

Before beginning to use supplements, it is important to discuss your decision with a qualified medical expert, especially if you are also taking other drugs, pregnant, or breastfeeding.

Collagen supplements vs. protein

It is essential to keep in mind that consuming collagen through food or using collagen supplements is not required in order to support the collagen levels or bone health in your body.

In point of fact, you may assist your body in the production of collagen and in the maintenance of healthy collagen levels and bone tissue by ensuring that your diet contains sufficient quantities of the protein of high quality, vitamin D, calcium, vitamin C, and zinc.

As you get older, it is especially important to eat a diet that is both balanced and contains a little bit more protein in order to maintain the tissue and bone in your body. For this reason, it is recommended by professionals that you consume more than 0.36 grammes of protein for every pound (0.8 grammes for every kilogramme) of your body weight.

Combining this protein-rich diet with physical activity, particularly weight-bearing exercise and resistance training, is a great way to support this goal.

Collagen supplements may help improve osteoarthritis symptoms, as well as the condition of the skin and the skeletal system. Collagen supplements may also assist increase skin health. It’s possible that they contain other ingredients that aren’t suitable for everyone, despite the fact that they themselves are thought to be safe.

How to prevent collagen loss

Although it is impossible to stop all of the collagen loss that comes with becoming older, it is feasible to slow down the process.

As was just said, your food and other lifestyle choices can have a big impact on the amount of collagen that is produced by your body.

Collagen formation is significantly impacted by behaviours such as smoking cigarettes and consuming an excessive quantity of alcohol, as well as by following a diet that is heavy in ultra-processed foods and added sugar.

On the other side, adopting a healthy lifestyle by eating a diet rich in nutrients, not smoking, and cutting back on alcohol use and heavy drinking may help delay the changes in collagen that are related to ageing and diminish the indications of ageing such as wrinkles.

It is possible that maintaining healthy collagen levels and general skin health can be supported by limiting or eliminating the consumption of particular foods and beverages while simultaneously increasing the consumption of others.

For instance, a diet that is low in substances known as advanced glycation end products (AGEs) may help promote healthy skin. Toxins known as AGEs tend to build up in the skin over time. They have the potential to make collagen more rigid and deactivate the proteins that are necessary for collagen repair.

According to both newer and older research, the meals that have the highest levels of advanced glycation end products (AGEs) are processed meat products like hot dogs and bacon, fried foods like french fries and fried chicken, and roasted and grilled meats.

In addition, eating a diet that is rich in high-quality protein as well as plant foods like fruits and vegetables, which include collagen-supportive and protective nutrients, may also assist in the preservation of collagen storage as well as the prevention of collagen damage and loss.

It is possible to reduce the risk of collagen depletion and damage by leading a healthy lifestyle, which includes refraining from unhealthy behaviours such as smoking cigarettes and drinking an excessive amount of alcohol and eating a diet that is abundant in fruits, vegetables, and other nutrient-dense foods.


The connective tissue, skin, tendons, bones, and cartilage all contain collagen, which is a type of protein.

It is engaged in critical body functions, such as the repair of tissues and the transmission of signals between cells, in addition to its role as structural support for tissues.

Collagen is a protein that is produced naturally by your body, but it can also be obtained through the consumption of foods rich in collagen and collagen supplements. Consuming collagen may improve the health of your skin, bones, and other organs.

According to studies, taking collagen supplements may be especially beneficial for certain reasons and demographics. One of these populations is postmenopausal women who have low bone mineral density (BMD), which can be increased by taking collagen supplements.

An alternative that is both healthier and more cost-effective than taking supplements is eating a diet that contains an adequate amount of protein, vitamin C, vitamin D, and zinc. You can slow down the breakdown of collagen and bone as you get older if you do this in conjunction with regular exercise.

Even while the loss of collagen that comes with ageing is unavoidable, adopting a healthy lifestyle can help guard against the loss of collagen, delay the appearance of indications of ageing, and enhance overall health.
